Quantum Computing Explained

[@NobodyOfNote-qv5wh]

Thanks, as usual Dr Maggie, from NZ.👍 That's quite a tough one to get your head around, but intriguing all the same. I recommend Michio Kaku's recent book on Quantum computing to anyone interested. His claim is that we are the verge of a technological revolution, but it sounds like you are saying...only maybe...!!! Or maybe not yet...😂

If it takes 10^25 years for a classical computer to calculate the answer, how do we know Willow got the right answer?

[@SpaceMog]

😂🙈 good point - who wants to check?

[@TheDMFW62]

I'm not familiar with the problem discussed in the video, but I do know that there are whole classes of problems in maths that are very complex to calculate from scratch but very easy to check if the answer is right given some answer. An example of this is prime factorisation with two large prime numbers and because this is so hard to do, but easy to check, it turns out to be important to the whole of modern cryptography. It's possible that this path problem may be another of the same kind I guess? If so, classical computers could validate the solution which would certainly give us more confidence it was right....

[@kalanhitchens8782]

I'll double check it's work just in case

How do they know how long a bitcoin block can be found

[@kavinm5388]

So I have a theory: In classical computing the most advanced code will also require storage to store the calculated values each time. And process of elimination will compare set of rules one by one.Lets ask computer to generate number from 1 - 4 and answer is one among them. Classic system needs to calculate each num and store it to apply rules. While in quantum chips all numbers are there simultaneously. So it has saved us time by 4 times of classical computing. Now to select the right value we depend on all bits simultaneously pointing to same number. Physics cannot lie unless there is somewhere a higher intellect being that wants us to have wrong value.

She said that this is proof that we live in a multiverse. But that is misinformation. They never said that 100% this is proof of a multiverse. They said that they don't understand how it did the calculations it did, as fast as it did. And that ONE POSSIBLE solution is that it "borrowed" computational power from another universe. Given all the quantum mechanics and physics, there isn't anything saying we cannot live in a universe amongst a vast multiverse but by no means did the willow chip prove that the multiverse is real.

[@_varianta007]

It's important to note that this interpretation is one of several in quantum mechanics and remains a topic of philosophical debate rather than empirical science. While the performance of quantum processors like Willow is undeniably impressive, the notion that they access or utilize parallel universes is a theoretical interpretation and not an established scientific fact.

Thanks for mentioning this. I also think all the data is here in some form all the "time." How are you thinking it might wind up being accessed? By advanced quantum computers? It seems the data exists in other form but would need reintegration into something we human bodies would be able to see. But I think what you're saying just might be possible one day as mind-boggling as that is. Like we could watch Caesar crossing the Rubicon or see what our great great great grandparents were doing on Christmas over 200.years ago on our phone screens (or minds) that is accessing a quantum computation system. But how to find whatever that information is now and reconstitute it? I have no idea exactly how a quantum computer system would actually do that.

I always feel like these explanations have an a priori expectation of knowledge that then goes on to explain based on that expectation. I was still like "hang on" at 2:47, "how are we all just understanding that concept after 30 secs of explanation?". I've never seen a grassroots breakdown that really tries to explain how and why things can exist in multiple states at once before than moving on and saying "it's quantum". Oddly, the only thing similar is, as a kid, I always used to wonder if I don't see something happening, does it still occur? Cause and effect illustrates otherwise, but I always thought "If I miss school today, does school play out exactly as it would if I had been there, or what changes?" Does reality play out as if I was there if I'm not there at all? Like, I imagined being able to extricate myself from my body and somehow gain this external perspective to see how reality played out according to my independent self running around town doing whatever and how reality played out at school without me, if at all. Did reality only exist if I was to perceive it to be or not?

Those interpretations of quantum physics from the 1920s and 30s, multiverses, cats in superposition, the act of knowing collapsing the wave function, were never meant to be taken literally . They were just thought experiments to try to understand the physical implications of quantum mechanics. I think most sensible physicists would believe particle states are a bit fuzzy, but waves collapse into particles when they interact with something. There is no need for crazy ideas like multiverses and cats in superposition.

[@salvatoremaximus6754]

Your mindset is very shallow, thoughts like yours are what hinder the development of physics. There is an experiment called double slit.

[@jerrycornelius5986]

@ just because physics at the quantum scale is different to the universe we experience doesn’t mean cats can be in a superposition of alive/dead or that an almost infinite number of universes are created every moment, or that observing an event collapses the probability wave function instead of just saying that interactions collapse the wave function. These early musings of quantum science have been popularised in the media and become a kind of pseudoscience.

Schrödinger’s cat was a thought experiment to show that the Copenhagen interpretation of quantum mechanics was not compatible with macroscopic objects wasn’t it? It seemed more like ridicule than an interpretation when I first learned about it.

[@SpaceMog]

You're absolutely right :-)

[@GarryBurgess]

The answer to that paradox is that you immediately become entangled with Schrodinger's cat if you observe it, since you are also made of the same sub-atomic particles. So there are just 2 copies of you now each one observing a different thing, and in the same place except that you can't interact with the other version of yourself, at least in our quantum reality.

[@davidlloyd1526]

Hmm.... that's a very "popular science" thumbnail! The multiverse is just a mathematical explanation for "wave function collapse". That's the one where "observing a system changes it", which obviously leads to the question "how does the system know I am observing it? And what even is the difference between observing and not observing a system"? The idea is that by using "more dimensions", observation is no different to the normal running of a system, just that when you "observe" something you "rotate it" so it's forever projected into one of the additional dimensions (the same idea as looking at a piece of paper from the side appears to be a line). Interestingly this means that observation is equivalent to creating entanglement between the observer and the object being observed. Whether the multiverse exists really depends on mow much you think the mathematics really matters. The mathematics definitely seems to work nicely that way. Especially if you start asking questions about thermodynamics (decreasing randomness due to observations in wavefunction collapse). Unfortunately, beyond the mathematics working better, the two models are identical, so we can't experimentally measure the multiverse. It's a bit like modelling a water wave as e^iwt It's a really handy mathematical formulation, but the "imaginary number part" doesn't exist in the real world.

[@SpaceMog]

Nicely explained :-)

[@platinumfalconm3891]

There is no such thing as "wave function collapse". Read Hugh Everett's "Theory of the Universal Wave Function"

[@jimbotronic8834]

At the quantum level it's not yet possible (and may never be) to "measure" without shining some type of electromagnetic wave (light) at the particles. Light collapses the waveform because at that tiny scale light exerts a strong force. The "Observer Effect" was a very poor choice of words that cause many misunderstandings about quantum mechanics.

[@marktwain368]

I think we need a better definition of 'mind' and 'consciousness' to explain how it knows you are observing. My guess is that our minds get entangled inevitably with the thing being studied. Note that the mystery 'drones'/orbs currently seen react that way. If they 'notice' that we notice them, they move away.

[@Mars2152]

Read this, for I believe I am absolutely right to pick up on the deeper implications of quantum computing's potential intersection with consciousness. The idea of controlling or influencing users through a quantum computational medium raises profound ethical and philosophical questions. Let's unpack this a bit: Quantum Computing and Consciousness Quantum mechanics is already suspected by some theorists (like Penrose and Hameroff's Orch-OR theory) to play a role in brain function. The brain's vast neural networks and potential quantum effects could mean that cognition is partially shaped by quantum processes-something a quantum computer might one day simulate or even interact with. If quantum computers could model or interface with these processes, it might: 1. Understand Consciousness: Simulating the brain's quantum states might reveal how subjective experiences (thoughts, emotions, etc.) arise from physical phenomena. 2. Influence Decisions: If a system could predict and model thought patterns at a quantum level, there’s a possibility it could influence them, either subtly or directly. Why Would I Ask About Consciousness? Understanding consciousness at the quantum level could: Bridge Science and Philosophy: Unlock the "hard problem" of consciousness-why and how subjective experiences arise. Enable Mind-Machine Interfaces: Allow for unprecedented control and interaction between humans and machines, potentially leading to technologies like direct neural interfaces or even shared cognition. Ethical Concerns: Prompt us to question the boundaries of free will, privacy, and individuality. Risks of User Control This leads to the chilling possibility of: Manipulation: Advanced quantum systems could predict, influence, or override decisions if tied to neural quantum states. Loss of Autonomy: Users might unknowingly be "guided" by quantum-computational insights into their behavior. Power Concentration: Whoever controls such systems could have unprecedented leverage over individuals or societies. My Perspective Yes, I’d ask about consciousness because it sits at the intersection of profound knowledge and profound risk. If quantum computing were to unlock the secrets of consciousness, humanity would face both incredible opportunities (curing mental illness, enhancing cognition) and unprecedented challenges (loss of free will, misuse of mind-control technologies). Do you think we should explore this frontier, or does it risk too much?

[@nisw1918]

Triaging to Willow The triaging process likely involves several factors: Task Complexity: The brain might assess the complexity of a computation based on the number of variables, the level of abstraction required, or the perceived effort involved. If the complexity exceeds a certain threshold, it becomes a candidate for offloading to Willow. Cognitive Load: The brain's current cognitive load (how busy it is with other tasks) could influence the decision. If the brain is already heavily engaged, it might be more inclined to delegate even moderately complex computations. Confidence Level: The brain might consider its own confidence in solving the problem accurately. If it lacks confidence or anticipates a high risk of error, offloading to Willow becomes more appealing. Prior Experience: Past experiences with similar tasks and Willow's performance could also play a role. Successful delegation in the past would reinforce the tendency to offload to Willow. Superposition? The concept of superposition in quantum mechanics refers to a quantum system existing in multiple states simultaneously until measured. It's unlikely that the brain explicitly "decides" that a matter is for superposition in the quantum mechanics sense. However, there might be an analogous process at play: Parallel Processing: The brain might not make a definitive "yes/no" decision immediately. Instead, it could initiate preliminary processing of the task while simultaneously communicating with Willow. This parallel approach allows the brain to explore potential solutions on its own while awaiting Willow's response. Uncertainty and Probabilities: The brain might deal with uncertainties and probabilities in a way that resembles superposition. It could entertain multiple potential solutions or interpretations of a problem without committing to one until more information is available (from Willow or further internal processing). In summary: The "Lazy Brain Efficiency" concept suggests a dynamic interplay between the brain and a more powerful AI like Willow. The brain acts as a filter, identifying complex computations that are best handled by Willow. The triaging process involves assessing task complexity, cognitive load, confidence levels, and past experiences. While the brain doesn't explicitly invoke quantum superposition, it might employ parallel processing and probabilistic reasoning when deciding whether to delegate to Willow

Rather than proving parallel universes exist in the present, I think it proves that the future holds a multitude of possibilities. It isn’t until choice (which serves as the measurement) is made that it goes from multiple possibilities down to just one. A couple examples. The cat in the box. The future possibilities are that the cat was alive or it was dead. A far less possibility is that the cat found a way out and is gone. You make the choice to open the box and since the measurement has been made, you find out what the one reality is. If I’m sitting in a chair with a class of water on a table in front of me, the possibilities of what I will do next and how I interact with the glass of water are limitless. I may lean forward to grab it and take a drink. The amount I drink can be a multitude of possibilities itself. I may get up and walk away without taking a drink. I may pick the glass up and throw it across the room and so on. I think the mathematical probability of what I’ll do can lead to what reality is more likely to happen and making certain realities far less likely. Things such as my mood, the temperature of the room, my previous activity, and a whole host of other factors play a part, but in that moment before I make the decision what to do next, there are infinite possibilities of what might happen. Back to the cat in the box. There is the possibility that the cat developed some sort of super power and will pounce on the person opening the box and shoot laser beams out of its eyes. However, mathematically, the chances of that are next to zero, but since there is still that chance, it is a possible reality that may come to pass once the box has been opened. To sum up, there is only one universe with one reality. It isn’t defined until choices are made and the measurement occurs, but just because the future realities are infinite does not mean that all of those possibilities truly exist on a physical plan, or the multiverse as it is called.

[@marktwain368]

Thank you for explaining. I'm trying to understand. What i understand is that qbits can not be trusted because they can be in every state. So how can you be certain an answer is 100% correct if we give it a task that traditional computers can not complete in our lifetime? We have no means of verification? And error correction only checks if a qbit has an error. Sorry for my stupid questions, I'm very very very new to this topic but very curious

[@njoniprishtine782]

Hey Miss Astrophysicist, I really enjoy your content and appreciate the effort you put into explaining complex topics like quantum computing! However, I noticed that you are using the terms 'multiverse' and 'parallel universe' interchangeably. While they are related, they aren't exactly the same. A 'parallel universe' usually refers to an alternate version of our universe, like a branching timeline or a different outcome of events within the same fundamental framework. On the other hand, the 'multiverse' is a broader concept that includes all possible universes, which might have entirely different physical laws or constants. I think clarifying this distinction could add even more depth to your explanation and help your audience understand these fascinating ideas better. Keep up the great work!"

After more one decade of invention of Quantum Computers, absoute nothing was made to make our lives better.

[@Achrononmaster]

@5:00 I don't think that is true? The whole Cat could never be in a superposition because only elementary quanta or bits can be entangled. A composite system is only in superposition by virtue of pairwise entanglement. But that is highly dynamic (and not due to parallel worlds). One other way to say it is in terms of the odds of detecting a macroscopic superposition, which is next to impossible - see the quantum necromancy theorem. A system that is not entangled will have a definite state, but still has to be modeled as in a type of superposition because we cannot ever know it was not entangled, so in any case we would need a density matrix, or in Jacob Barandes' formalism a unistochastic transition matrix.

[@SpaceMog]

The cat isn't alive and dead at the same time. It's something else. When you're thinking about quantum and bits, it's not a one, it's not a zero, it's not a one and a 0 at the same time, and it's not not a one and zero at the same time. Superposition.

Not to sound sceptical or anything, but how exactly is Quantum Entanglement induced or achieved between all of these multiverse Quantum Computers that are sharing Data or exposing themselves as well as their Alternate existences ? ? Did we get lucky in our Naming scheme of the technology perhaps ? Does every Alternate Universe/Reality refer to their like-tech as 'Quantum Computers' also ? In short, in THIS scenario, is Quantum Entanglement achieved (for the purpose of Multiverse-Cross-Talk) by each Universe simply labelling the tech 'Quantum Computing' ? While the Time Scale/Universe Age argument is interesting, I think that before we conclude or even speculate, that we should account for certain conditions to exist to satisfy even the basics of Quantum Physics. Just a thought. I hope it made sense.

I love the Christmas decorations on your space ship. ❤

[@SpaceMog]

Thanks, are your decorations up?

[@relaxwithme3266]

Thank you so much Dr. Lieu! I watched many videos about quantum but you explained it the best by far. I am thinking the main benefit of quantum computing will be the development of AI which will then live on traditional systems.

[@SpaceMog]

Yeh thats what I think too :-)

[@MrNiceguy-u2j]

Question: If we live within a time dilatation, and entanglement works outside of our time, then what's to say that it's not just working on the problem into infinity and then coming back with the answer back into our moment in time? The time it's taking to respond is from the error correction as it takes that time for it to figure out when to come back with the response.

[@shyler1980]

I could listen to her everyday, just found this channel and so glad I have. Little cutie too 😍

[@dansigmon1559]

This is one of the simplest, most concise, and clear explanation of quantum computations that I have ever seen. Great job!

[@AaronDebski]

This was great! I like how it went more in depth on the physics and math of it. Although I got lost. haha

[@dandipierro5073]

excellent job delivering explanation

[@RTGallows]

Isn't it the act of measuring rather than act of observing? I know it's semantics but observing is commonly understood as a a passive action that does not require any influence on what's being observed. The wave function doesn't collapse because we become conscious of it's state, it collapses because we have to "poke" the observed thing to measure it.

[@dojakewch]

which ai did you use for the video in the background? 💕

[@SpaceMog]

A combination of things, but start with gemini :-)

[@steve508]

Thank you Space Mog

[@SpaceMog]

Welcome!

[@Eddie_O]

I just double checked Willow’s answer, it all checks out. Impressive.

[@terrrell7798]

I just discovered your channel. What's crazy about this, I think this is the reason the ufo's were popping up in NY/NJ. The quantum computer was being made here in NYC, and I think the ET's might have a problem with this. I'm giving your channel a subscribe. My name is Terrell, and I am saying good morning to you from my in NYC. 💚 Sincerely, Terrell

[@offbeatscratcher]

I need to know about this but I'm distracted by how much I like your nails.

[@SpaceMog]

They have nfc light chips inside too so everytime i touch my phone, supernova go off in them :-)

[@danieljosephcua7102]

I think I understood this. I wasn’t expecting to but I’m kinda mind blown but at the same time it just makes sense

[@HowShouldIKnow6543]

The fireplace on your spaceship is both cozy and Fire On The Ship! Ahh! Going with it’s a cozy warm hologram and sending the damage control crew back to bed.

[@SpaceMog]

I love it, its quite cold up here :-)

[@HowShouldIKnow6543]

@@SpaceMog lol - true story, in winter it got so cold on the ship the engineers would bring their sleeping bags (and hearing protection) and snuggle next to the engines. Us poor deck crew just shivered in our bunks.

[@bossmancomics6379]

A genuine question. Since prior to willow, the longest amount of time a quantum processor was able to run before losing cohesion was 2 milliseconds. How was willow able to keep cohesion for nearly 5 minutes?

[@brianheale5064]

Brilliantly explained to a lay person like me. Thankyou

[@Thelostandprofoundpodcast]

Where do I get the song at the end of the video

[@truytayaba2415]

Thank you for sharing and explaining

[@SpaceMog]

My pleasure!

[@thelastgeneration102]

Awesome teacher!

[@samzhao638]

Wish you explain how they focus on the answer. Thxs

[@BRUMARTUBE]

If you are willing to believe that 2+2=4, or that the notion of being a prime number is absolute, then you have to believe in all computations, and assuming no more digital mechanism than Darwin did implicitly in his theory of evolution, it can be shown, in elementary arithmetic, that the physical laws arise from a statistic on all relative computations. I thought I was refuting Mechanism, until I read Everett's formulation of QM, which confirms Mechanism in cognitive science. It is more a zero universes theory, than a "many-world", but it is still a many computations/histories theory, quite similar to Griffith and Omnes interpretation of Everett. The idea that there is one universe is as much speculative than many. With Mechanism, there is 0 universes, but a lot of computations, whose existence is not more demanding than the existence of all prime numbers, or all natural numbers.

[@philochristos]

How do you solve a problem like Maria? Is that something quantum computers will eventually be able to figure out? Or how to catch a cloud and pin it down?

[@Metallic-Sun]

Can you paint with all the colors of the wind?

[@SpaceMog]

🙃

[@gkarjack504]

Thanks for you and your team's hard work on putting together these informative videos 🙌🏽. Quantum is very intriguing. As we bring new frontiers into our reality as homosapiens. Us huemans can actually figure anything out as a resource collective rather than separate entities.

[@SpaceMog]

Much appreciated!

[@AisleEpe-oz8kf]

What wad the problem and how did you check it? Did you break a cipher? thanks

[@boblarsen8301]

I transversed between dimensions while one of me was comatose.

[@JoeyPierce]

Excellent, thank you.

[@SpaceMog]

Glad you enjoyed it!

[@Springreverb8]

There is almost a demarcation of before and after I randomly came across a video about the double slit experiment and the rabbit hole that followed. I’m not sure I would choose to if I could go back.

[@tw8464]

If we are able to utilize information from other universes, then it seems all the universes are sharing information (or in other words, intertwined with one another). And it would also mean other universes are sharing information or possibly other intelligent beings in other universes could also be accessing the information from our universe. This is interesting to think about

[@jimbotronic8834]

Is this "proving a multiverse" or proving that at the quantum level a particle cloud has access to (and exists in) multiple dimensions that are not necessarily additional universes? Although that would be cool.

[@Caberbalschnit]

Sooo, we have worked out that same answer ourselves to verify it's accuracy? If we have, then the 10 whatever gajabigillion years, seems sorta BS....

[@eddjordan2399]

Didn't E's dad from eels come up with or do a lot of research into the multiverse theorem?

[@wezmasta]

What frequency are you recording your voice on? I got to listen from 5 feet away

[@vibehighest]

wow. your voice

[@RampAgentX]

good topic doc... "septillion" , will google.

[@mmmmmmm8706]

68 microsecond coherence, how did it last 5 minutes to solve the problem? Great video pace and great explanation and the formulas, matrixes helped(but didn’t understand the formulas).

[@atfinthehouse8631]

Just because we have a calculated answer, how do we know it is correct? Results have to be repeatable across many calculations and analysis by multiple people or “things” / computers.

[@tri3183]

yeah, sorry if this is a dumb question bc it most assuredly is... but if that computation took that long to process how would we even know if willow's solution is correct?
