Dr. Michio Kaku, the renowned theoretical physicist, walks through the evolutionary journey of quantum computing, from analog to digital to the quantum era. Quantum computers hold immense promise because of their ability to tap into parallel universes, which boosts their computational power exponentially. They could revolutionize agriculture, energy, and medicine, solving complex problems like creating efficient fertilizers, achieving fusion energy, and modeling diseases at the molecular level.
The race between major tech companies and intelligence agencies to actualize this power is intense, as they could redefine industries and even global power structures if they succeed.
The endeavor isn’t without challenges; we’ve yet to create a fully functional quantum computer. But Kaku envisions a future where quantum computers unravel complex equations, potentially shedding light on profound cosmic mysteries.

@@sassa82 I agree, his best days of research are likely behind him. But he is an educator and communicator, he has a great ability to explain complex concepts in a entertaining and easy to grasp way. He still has a wealth of knowledge, even if he isn't working on the bleeding edge anymore. There has been a lot of overlap in his books, but his specialty (i.e string theory) has more or less been stuck at a road block for quite some time now. At least in his later work he has expanded to write about other concepts. So yes, maybe not such an active physicist, but his role and career now is in getting more people interested in physics, and providing us "normals" with easy to digest content. He also still teaches at NYU and does some work on string theory, keep in mind this flavour of physics is not experimental, it's mathematical.

It is a bit strange, most experts in actual quantum physics are far less optimistic and don't believe in quantum supremacy. There seem to be very few applications where QC actually manages to reduce complexity (it's just a bit unfortunate that prime factorization happens to actually be one). The only really big application is the simulation of quantum systems themselves. I think a lot of what he is selling here is more his personal beliefs rather than a scientific take on the matter.

[@theplouf5533]

He doesn't explain anything and worse, he says a lot of false things to make it "easier to understand". (Like the "big bang" is just a rapid expansion) Having several universes is nonsense, electrons are not influenced by something that is still only theoretical. The Qbits do not have an indefinite number of states, since it itself says that its reading fixes the result at 0 or 1. The principle is rather that the calculation is done in all the states at the same time. The computer therefore does not calculate the result, but gives the only or one of the valid results. (as if your calculator gave the correct number, without ever having explained how to obtain it). But it remains a calculator. It's like dropping an object will always have the same result, a Qbit "falls the probabilities" to give the result.

[@connorjones3081]

Quantum Computing is a different paradigm, and therefore should not be compared to our everyday classical computers. It will notreplace them. When a qubit is observed the superposition collapses, to either a '1' or '0'. Where this information is passed back to a classical computer. The same logic is applied for very hard problems, so classical computers won't see the processing, simply the result. There is quantum memory, which operates differently to RAM or non volatile memory such as hard drives. Quantum memories often hold the state of a qubit (usually a photon), for a very small period of time. This mostly allows for quantum repeaters and thus the transport of quantum information over large distances. Hope that answers the questions

[@Grawbad]

That is an inherent problem with quantum computers. Or at least that is what I understand from another one of these videos with a different narrator. Basically, it doesn't pass zeroes and ones like a traditional computer, it needs to pass positional data from one particle to another. The problem is qubits are prone to decoherence, which in this case means they can lose their state. Sorta like a modern computer losing a portion of data and becoming corrupted but in this case incorrectly reporting data which in turn corrupts the data.

[@alperwal200443]

Quantum will replace conventional lmao. Would be great if humanity will build 1000000 qubit computer in 100 years which would be capable of 5 digit number factorization. May be this will help nuclear fusion enthusiasts to finally build a reactor that produces more energy than consumed.

[@connorjones3081]

@@alperwal200443 They will not replace them. Many tasks which run on classical computers use information that has been stored, digitally copied and recieved. This is not possible on a quantum device due to the no clone theorem. 1 million qubits, could also be possible much sooner than in a hundred years time. With suffecient error correction and addressing losses, some quantum computing paradigms could be scaled very quickly. We may see this number before 2040.

After failure like that dude should just retire and enjoy his well earned pension for his hard work - in science we appreciate even the work that didn't produced results that we hoped something would produce as this still gives insight as to what ideas we can discard thus in future we can search for better ones. Nothing is wrong about the fact that string theory was being researched. It's just wrong that it received more public attention than it deserved considering that it's a theory about nothing. But he definitely should stop with this public appearances spouting even more nonsense especially when he's not even working in quantum computing. He's just misleading public for no good reason.

I love the explanation. And the illustration of a qubits make it so much easier for me to understand it and remember it. However, when we see the current issues with AI, I’m not sure having something so powerful in our hands, as human, is such a good idea. I mean, with the good comes the bad.

[@_skiesblue_1256]

Exactly. With great power comes great responsibility, and this responsibility will not be delegated to the proper people, efforts, and law/the justice system will fall even farther behind. It's just inevitable. AI is certainly a big current issue, and I can only forsee it worsening. No restrictions, no limitations. Law cannot catch up with it. There is no one to police it, the Internet is literally the Wild West lol. (*insert* blurb about cyber security tied to quantum computing since im an analyst) Quantum computing will heavily impact cyber security, and when that is affected, so are the systems and countries of the world. New and varied strands of malicious processes are deployed everyday, disrupting people's lives like: hacking into critical infrastructure like water and electrical systems since everything is connected to the Internet, the ability to more easily encrypt patient data in ransomware deployment on hospital systems and sooooo much more. I am in the US, I wonder in what phase of quantum computing other countries are at. It seems like a quiet armsrace.

[@markn6941]

AI will help us solves QC, then AI will merged with QC and rule the universe. We will becomes their batteries.

[@iamhawkeye3162]

This is probably the best explanation for quantum computers I’ve ever watched.

[@bruce6944]

Fantastic explanation!

[@Bandro09]

This is the best explanation of Quantum Computing I've seen. I finally get it.

[@vitr1916]

It is really hard for a computer in coherent state, when it doesn’t know when it is day and night, hot or cold….

[@deterministicatheos5540]

Exciting times!

[@jollymess1]

Nice explanation.

[@christiansmith-of7dt]

Can you believe that one day they are going to develop a computer that knows how to make people feel better

[@austinclay427]

Heh, keep praying buddy

[@OriginalPuro]

Can you believe that one day they are going to develop a computer that knows how to make people feel better?* First you'll have to make me believe that you can type a sentence properly.

[@programthis3805]

its called an anti depressant lol

[@demetriosbooras8538]

It exists now!!

[@csanton3946]

or how about a computer that can suggest a ruling ideology that works for everybody to live in this world conveniently and crushing all these economic theories that is just a one big experiment that unfortunately cannot be concluded easily because the experiment runs through multiple lifespan and generation (beyond capitalism, socialism) what is the best way to live in peace where all of us are benefitting on the resources here on earth

[@dsolis7532]

I’m a physicist and I know he is trying to communicate complex concepts in a simple way, but this is grotesque haha

[@ScottHoltshousen]

Oh God, was just coming here to comment this. Prominent physicists seriously need to come up with more accurate ways of conveying the reality of quantum mechanics.

[@2CSST2]

@@ScottHoltshousen Prominent physicists in general are actually pretty good at doing it. For instance there's Sean Caroll, Brian Greene, etc. It's just Michio Kaku who's particularly always done this thing where he interprets physics as if he was an amateur who doesn't really know how it works even though he must given what he does.

[@jimjamjerry]

What’s a better way to put it then? I’m curious how a particle can be in two places at once

[@kasondaleigh]

Key word: Theory. An idea is not a fact.

[@lloydbyrne3440]

I feel very dumb reading theese physicist comments 🤔

[@Yodakaycool]

Glad to see him back

[@BetterSachet]

Whatttt an explanation ❤❤❤❤🤯🤯

[@EduGroove2024]

I like this guy, he makes me love physics more. stay healthy always, Mr Kaku.

[@sassa82]

He is not a serious physicist as Sabibe H alludes to.

[@ernestoduenas2466]

​@@sassa82yeah that's what a ignorant woul say ...we got you .

[@4shadow2]

You love the science fictional side of physics more. Things like multiverse, string theory and theory of everything are fantasies which you have faith in which arent even real

[@MuonRay]

Quantum computing is kind of already a thing, with a ton of learning materials online already from companies like IBM and Xanadu with even their own coding libraries, in python mostly but some other languages too. Many operational procedures exist in the adiabatic and gate-based quantum computing domain but, and this is critical, very few existing in what I like to call the quantum problem-solving domain. So until this leap happens quantum computers may remain just resources for research, which is fine, but still restricted. Some games, like the CHSH game and others, have been bridged to classical optimization problems and some things like quantum Fourier transforms may be the first to really become mainstream in the problem solving domain however I think the thing to really pay attention to is networks and communication systems of which the concept of an entangled, many-body, internet of sorts is the real thing to look out for not quantum computers by themselves per se. After all, we had classical computers long before the internet but once they became part of the internet they became far more than the sum of the parts and emerged into a completely different beast. A quantum internet may really be the next revolution.

[@Woodwender455]

good thing we have the military budget to develop a quantum internet 😂

[@Woodwender455]

I mean, imagine what the military could do with quantum computing…modeling hydrogen bombs? They would be the first to develop a quantum internet imo.

[@muhammadusmanbutt3341]

why this so satisfying? amazing stuff

[@lokeshkumarsingh6120]

Perhaps the best explaination of quantum computers

[@JKDubski]

This video provides a basic understanding of Quantum Computing fundamentals, but doesn't answer the complex questions surrounding it. Explain it to me like I'm smart! How do we interact with quantum computers? I.e., how do you input? What are the hurdles that are currently preventing quantum advancement? Does Quantum Computing solve the encryption issue it creates? What alternatives to encryption based on large primes are there? What types of problems are quantum computers not good at? Too many questions for an 11-minute video to answer, I'm sure.

[@sage_x2002]

Veritasium does answer this well

[@JKDubski]

@@sage_x2002 Oh much better! Thank you! His video certainly answers my questions regarding encryption and what kind of problems Quantum Computers are not good at solving. I still don't get 1) how we input into a Quantum Computer and 2) when Michio Kaku explains that Quantum Computer modeling is going to overhaul prediction modeling and medical development, how exactly do we get the model? Perhaps an input question again, but as to why Quantum Computing will overhaul anything other than RSA encryption, I'm still at a loss.

[@edwin.jansen]

As always the stuff that Michio talks about was in the making in the black projects for at least 20 years. It is not hard to predict the future if you are in and know when what is planned to be released.

[@shahinaghamali7797]

it was incredible thank you kaku

[@peterwelch114]

Thank you professor, you take an enormously difficult field and break it down so that the general population can understand and embrace it.

[@SZY_]

Michio Kaku is valid in my hood

[@phoenixvette]

I really don't get the trend of putting up a background and then filming outside of the background, he's in a beautiful room and there's a C stand and white backdrop looking dumb.

[@CodingAqyanoos]

Computer programmers have changed the world. Proud to be part of it.

[@nazriahmad3158]

thank you .. easy to understand .
