[@NicholasKoeppel]

Quantum computing is just the observed movement of an electron through a quantum stated material… depending on the dimensionality of the quantum state used: you can reduce the time it takes to complete an action in the transistor well(as with each dimension reduction, you halve the time of wave response; all the way to dimensional 0, which gives you an instance well response)… The idea that’s introduced at dimensional state 0(or D0), is that a computational state of each well, would natively occur when introduced to a specific request… Now if the engineers were being honest about how it actually worked: they’d they’d tell you there is no “instant response”, as you just get closer and closer to an infinite; your always limited by entry and re-entry of the election…. {if your unfamiliar with how modern chips work, you basically have numerous waves that can be added to a well, and as those waves are combined in the well, they create an amplified or non-amplified well response; if you can widen the accepted wave ranges you can level out responses and have numerous responses at different wave level interactions in a single well. The big advantage of what quantum computing will do is clean those wave length responses and allow many many more responses to occur within the same well, all with minimal distance required between the wave interactions}. It’s one of those things that could be possible, but is much less useful then you think it would be, even when it is… In the end the best use of a tech like this would be for running efficiency models… While Quantum Computing does offer an advantage over modern high-low transistor well technology: the cost to operate, and lack of efficient manufacturing processes; it just doesn’t make sense for the amount of advantage, that could be achieved for much less in other ways… Once those avenues are perused, and this is the only advantage left; it’s possible this might be a future tech that’s used… D0 systems are still a ways off though anyways…

So in that scope, all simple outcomes are "known" and observation is the outcome of where the coin falls, and since all outcomes are "known" they're are immediately accessible and do not have to be calculated.

There is no evidence proving that quantum computers require parallel worlds. This video is a promotion of the 'Many Worlds' interpretation, which is just one of several interpretations of quantum mechanics.

[@abdullahunal1108]

I think concluding that superposition and quantum properties are signs of a multiverse is far-fetched. It's just that the rules governing things at that scale are different from what we experience. This doesn't necessarily imply that what we observe in the quantum world necessitates the existence of parallel universes.

[@SuitedPup]

That’s a fair assessment, but the many-worlds interpretation is a plausible explanation. It indeed may be the case that quantum computers are performing parallel computing in parallel universes. More likely, it’s just an apt way of describing / modeling whatever is really happening.

[@sethlamancusa]

Seconding what the other commenter said. Personally I think many worlds sounds far fetched but makes way more sense than your traditional copenhagen interpretation. It's actually the simplest explanation of what we observe, since it doesn't impose wave function collapse. Sean Carrol advocates this argument really well

[@Michael-ul7kv]

Very far-fetched

[@sethlamancusa]

@@Michael-ul7kv I agree actually that its unlikely that "many worlds" is the right way of thinking about the entire wave function and its splitting, but I do think it's the closest thing to a philosophically sensible interpretation and the best starting point for continuing to think about foundations of qm, which has been woefully neglected for the past century

Hartmut Neven is who I’d want in charge of quantum computing development if I were CEO of a megatech company. He’s brilliant! He also considers the only analytically plausible explanation for the phenomena of quantum physics is the existence of the multiverse of multi parallel universes. As mind-boggling as it may seem to us humans, and as hard as we’ve tried to disprove its quantum physical ramifications, the multiverse theory is becoming more and more accepted. I guess Nature really doesn’t care what humans think of it.

[@m-multiverse9918]

If and when the Multiverse Theory is proven and accepted, then begins the “nuts and bolts” detailed sciences of why and how nature allows this existence of multiple parallel universes. It’ll be a whole new “can of worms”, as the saying goes. Could it be that, as we probe deeper and deeper into nature, the more and more complex it gets in a quest without end? Nature may be infinitesimal and infinite. Thus, it is probably impossible for us humans to ever establish, as Einstein hoped, the ultimate fundamental laws of nature, or the ultimate “equation of everything”.

[@ralfbaechle]

While the existence of the multiverse is unproven and probably unprovable I learned it to be a great way of explaining things at a popular science level. Computer architecture has always been my thing. And so has physics been, so quantum computers are just the next crazy thing I'd love to work on.

We may not be able to prove the multiverse theory, but when he mentions a "parallel" universe i believe he's referring to the duality of this universe that we're experiencing today. Our universe is technically two realities, and could potentially be conjoined in a state of superposition with equipment like this. We harvest anti-matter, and the existence of anti-matter is sufficient evidence of a parallel universe that's made up entirely of anti-matter.

[@h.h.c466]

For me the Grover Algorithm is like a parallel suspect line: parallel witness checking all suspects simultaneously, where each suspect reacts to the witness's criteria without direct marking. With each iteration, the suspect matching the criteria becomes more prominent, while others feel increasingly overlooked. This repeated process makes the correct suspect stand out more, ensuring they are identified with high probability in the final check .... probably more complicated in the setup with the Repetition of Oracle and Diffusion but for me it helped getting the rough idea understood.

My basic understanding has been that surfing the multiverse gives the illusion of free will and is the basis of consciousness. Glad to hear that Hartmut Neven had a similar thought. Would love to learn more. I marvel at what leap someone had to have to harness the multiverse in computing. Does it mean that there are a huge number of quantum computers in "many worlds" running the program in parallel? Once a reality splits off from this parallel path do we loose connection to that machine, or is that how the probability is calculated?

[@lucasinatur]

This many worlds or multiverse interpretation of quantum mechanics is not even testable or provable in any way. I really don't like how he wasn't more clear about his use of metaphors, especially with such a large audience. Additionally quantum computers are not normal computers which can run a lot of things in parallel, these things exist already. Quantum computers work fundamentally different and the "parallelization" happening in them is completely different from traditional parallelization.

​@@lucasinatur Lucas, I am an artist, one who wanders the labyrinth of scientific discovery, embracing my peculiar nature. As an artist, I strive to decipher the intricate patterns woven into the fabric of what I read. For a scientist, the multiverse theory may hold little utility, for it stretches beyond the confines of our testable reality. This boundary marks the edge of hypotheses, a threshold many are content to honor. I understand and respect this devotion to empirical rigor. Yet, as an artist, I am liberated from the shackles of the provable. My imagination embarks on daring voyages through realms of "what if," enthralled by the boundless expanse of possibilities. Scientists unveil their finest theories, and my mind dances with these concepts until they spark a revelation. Much of it is fantasy but that's ok for me.

So the key is to have an insane ammount of storage space, full of data, that was translated from text to algorithm... and then to code. Then, run that through a processor, which has inputs from the user, to achieve different tasks. And all that funnels into a display, which can show images of data that has been quantized. That's the most basic setup. Then the next logical step, is to add machine learning to the storage unit, to further integrate whats been stored. Then, youd start feeding more information into the storage unit, for more abilities on the processing and display side. And forget computer code. The best way is to create algorithms that can translate speech and text, into the computers own language.

[@Toughbeard]

I would like to see the brute forcing capability of the QC against the current 256Bit encryption. Now he said the processing power is 1 Billion times more at the currect phase and here is a quote "AES-256 encryption is virtually uncrackable using any brute-force method. It would take millions of years to break it using the current computing technology and capabilities." My math may not be on par with this guy but I think he said he can brute force the AES-256 in 0.365 days... thats 8.76 hours... so a lack of how many millions of years is the unknown in this equation.

[@brianegendorf2023]

On one hand, he is going for the technical aspects of what Quantum Computing looks like. But I just want to point out...that the best analogy I can give to simplify the advantage of such a computer..think of it this way..Everything our current computers do requires some kind of bandwith of data that is usually distributed across a bus..(a bank of circuit lines set aside for a specific purpose. Like a RAM bus, or I/O bus). Buses get bigger every few generations of computers to handle more data going back and forth in the computer. A single bus can have 64, 128, 256 lanes or more to accomodate all of the digital 1's and 0's passing through them. Like lanes of a highway. Imagine if your local highway had 128 lanes to accommodate all of the traffic driving on it. Now, with q-bits in quantum mechanics, the "1"'s and "0"s are replaced with 0-10*x^27 or something like that as a single digit. Suddenly, all of the traffic in the 128 lane highway fits into a single lane, and there is still a LOT more room for cars before you'd need to create a second lane. Like every car on the planet and THEN a lot more could fit in that lane. And the thing is. because its actually a single "digit" on that quantum board, it doesn't take any longer for a digit of any value of that q-bit to reach the end of its trip. If you put a large number in a standard computer, it takes several clock cycles to fully move that information to the next part of the circuit. In a quantum computer, moving a number that fits in that q-bit range only takes....one clock cycle. Can you imagine how fast those computers will be when they finally start doing practical things? We might actually have to purposely slow the user interface portions of the computer down to make it even usable by humans.

The fact that gold, when it is in a monatomic state, can achieve superconductivity at room temperature makes me wonder why nobody has attempted to design a quantum computer that utilizes that instead of using the supercooling method which I would think actually ends up costing more in the long run. Of course I imagine it would be difficult to figure out how much monatomic gold it would require. It might end up being cost prohibitive. However there are more ways of obtaining monatomic gold aside from just using gold leaf and transforming it into monatomic powder through a chemical reaction. It can actually be harvested in nature via several methods. Though it could create a possible purity issue.

He's like the Kanye of the Quantum computing world.

[@Raydensheraj]

And Kanye West is just a Xanax version of Farrakhan.

What stocks to buy besides QUBT?

[@ChowTY42]

IONQ

[@plateer42]

Show some results. Just another pretty presentation.

[@AI_Image_Master]

He's just hitting all the important buzzwords and explaining nothing. As he said he has been working on Goggles Quantum computer for 12 years and basically at this point has nothing really to show.

[@unknown_-ed2rs]

I'm no expert but i'm pretty sure it's "thing is in multiple states at once" not "the multiverse is real and there is another version of this room where we are sitting in a different order"

[@rickyale1618]

The first problem is that companies are spending billions trying to make quantum computing work, only to back off because it’s too expensive. Instead, we should invest that money in educating the 8 billion minds around the world. Minds are priceless, each with trillions of connections.

[@Laralinda]

So he must have some kind of theory how this "smartphone-NMR" should work. What is it? How it is supposed to work?

[@ramsenn2680]

So is QC just replacing current physical silicon/electricity computation with wave conversion of the same threads, thereby allowing almost limitless computation in a short time since you’re not bound by physical elements?

[@TheQuantumOwner]

Can someone help me understand what he meant by this? "Please note how I find one item in a database of four by only doing a single call to the database, this is something you could not do on an ordinary computer".

[@corwinzelazney5312]

Love the way he pronounces quantum: kw-ant-um.

[@Exen88]

Cool stuff. The qpc computes the equation in multiverses simultaneously to achieve the result faster. Sort like how Naruto clones himself 100 times to achieve a task very quickly.

[@christophessig5686]

Out of all possible multiverses, we live in the one, where he chose this outfit - or maybe he just asked his quantum-computer what 16yos would think looks cool.

[@mactubex]

I think they do not know time has passed, they have lived in the lab since 1997

[@RoySmith-lb9vh]

Where he is from, it is cool

[@tysonfinn1470]

After he explained it all perfectly i still didnt understand anything but i think his sunglasses are cool.

[@benhammond6717]

So this guy is the main super villain in the next Bond movie right?

[@hexdragon35]

Incredible is an understanding. Revolutionary may be the only word to describe this advancement. And at what a time, when humanity faces its greatest crises of extinction through global warming. Here’s to hope, growth, and human advancement ✊🏽💪🙏

[@michaelk.2210]

Any breakthroughs made by quantum computers so far? Anybody please.

[@VioletWander314]

So fun, I call these pocket dimensions! (All simultaneous possibilities positionally)

[@josh48776]

When will quantum computing move to space? What I’m referring to is the cooling issues we have on getting those computations. It’s costly to mimic deep space so why not put the computing devices in space where it’s almost below kelvin already and receive those computations on earth.

[@Kellastico]

So all in all, what I’m gaining from this is that Quantum Computing is almost essential for technology, like AI and Algorithms *because of Superpositions. In simple terms, “Quantum Computers will be able to overthink and provide solutions for each overthought” But as of 2024, Quantum Computing won’t be as practical or relevant yet until we have creatives and engineers making more practical, applicable products

[@TheDeacon-z9m]

One of the first killer apps will be cryptography. Because QC threatens to break all current encryption within next 5 years or so, quantum-safe cryptography should grow quite rapidly. Latter requires quantum computers.

[@shanghaiffgg]

It feels like we are building the basic tools (AGI, quantum computing power) which will ultimately allow us to understand the answer to these questions. Feels like the human brain alone can't explain them since the brain is just a consequence of the system.

[@Xx_BruhDog_xX]

Next time get some aviator goggles. With that fit and that dome, you could probably make it work.

[@RobertSutkowski-l7h]

Thank YOU 👍 BRAVO 👏👏👏👏👏

I saw this title and thought to myself, ''literally!"

[@mrsquiggles1379]

I couldnt imagine being the lead of a bleeding edge field as this. Mapping consciousness? this is wild

[@dinarwali386]

Fascinating: What are the biggest challenges to building a large-scale quantum computer?

[@BarryKort]

Decoherence is the chief issue to deal with. Entangled qubits tend to decohere for multiple reasons, limiting the number of computational steps that can be completed before decoherence ruins the calculation.

[@jmanakajosh9354]

​@@BarryKort Thank you! That's enlightening.

[@sikhathakur8349]

Ted's videos are the most informative and excellent ones

[@JayyyMilli]

Yeah but sometimes a video ends and I can’t remember what I learned Loll

[@dans.8198]

This is what I learned from this video: Quantum computers are not computers (because that's what I used to think). I also assume they are cooler because they need very low temperatures, although this is also *not* explained in this video. I guess I'll check back in 10 years, hopefully researchers will have actually understood what they are.

[@Trip_Hungry]

What if we were not supposed to advance this much? This can be one of the possibilities to future?

[@jvlyenlimon9319]

With quantum computers, I want to jump into an universe without having to pay my rent.
