What, nokia sponsored this video

[@hondo190]

The most surprising, overwhelming and uneblievable thing in this video is "presented by Nokia".

[@whf_frosty]

Do you collaborate with Chinese companies?no… Go on🤨 That had me laughing 🤣 like yo😂

[@rendermanpro]

Sponsored by Nokia. I would like Nokia unbreakable quantum computer

[@homewall744]

They already have quantum-defeating encryption algorithms that run on regular computers and networks. NIST just made some announcement on standards for them.

[@soliveirajr]

Not sure what is more overhyped: quantum computers, fusion reactors or Tesla FSD...

[@Charles-Darwin]

Depends on the echo chamber you fall victim to

[@paulb9156]

Don’t forget neuromorphic computing.

[@robertlee8805]

Tesla FSD or should we call it FAD.

[@casey2230]

bro forgot about graphene

[@guiltazaour2871]

Quantum mechanics is like nuclear fusion, always a few years away

[@Z6D4C4]

Hannah Fry is such an excellent host.

[@bakerkawesa]

Among the tech fads, including blockchain and artificial intelligence, quantum computing holds the most promise. I'd bet everything on it.

[@jonathanhill9504]

None are fads, but AI and Blockchain are a lot more mature and have already proven a lot. AI in particular, over the last 30 years, has already improved so many lives and products. Only the latest AI developments have caught on (chatgpt) because they're more user-friendly but AI has been used in products long before The Terminator was released

[@davidspagnolo4870]

Tech "fads" are only "fads" until the laymen who think they're "fads" lose interest and the serious people actually get back to work.

[@kevinjeon2250]

[@AdmiralBeethoven]

Nice one

[@thegiggler2]

At first I thought they were walking up to a really cool, imposing elevator. Should have named it Otis

[@homewall744]

Lots of "could" in this faith-based wish for quantum computing power being especially useful with all this massive parallelism. When will it become "can" and "does"?

[@Nabrolo]

It's similar to Fusion generators. It's part of the bleeding edge research that we know how it works for the most part, now we just need to scale it up.

[@PhyrexianHex]

Less than a hundred years ago we discovered and harnessed the power of the atom. It took thousands of years of science to get us to that point, and we're moving at an INSANE pace since then. Technology has progressed so fast in the last century comparitively that it's hard to remember that practical electrical light has only existed for less than 200 of the last 6,000 years of human civilization. We are moving at light speed technologically. We should be worried, honestly, that we're moving TOO quickly.

[@FranzBiscuit]

It's the same old story: "quantum computing is just 30 years away"™.

[@Nainara32]

IIRC I don't believe that there have been any published cases that have held up to peer review where quantum computers have outperformed traditional computing. It makes one wonder if hype over quantum computing is a modern form of a SDI/"star wars" program intended to divert Chinese state-directed resources toward wasteful projects.

[@richardconway6425]

Yes, I think that's true. I would go as far to say that some of these 'commercial' quantum computer companies are complete scammers. D-Wave comes to mind, but I think there are others too. The 'hype' is about the imagined potential, rather than any current reality. It's very hard to imagine this happening anytime soon, especially not within a decade. This and agi are the hardest of problems, and I don't expect to see either any time soon. As for your 'misdirection of resources' suggestion, that's an interesting, and plausible idea. For as long as there is the possibility that it might result in a useful computing machine, then we will feel obliged to do it, but there may indeed come a time, when we have satisfied ourselves, that neither we, nor anyone else, is going to be able to do this. At that point, the ruse may continue, for the reason you state. It may even have happened already.

[@weepingcamel1]

wait, the way she explained quantum computing made it sound like just parallel processing, there's gotta be a fundamental difference right? My laptop has some 20 cores, and can do 20 threads at the same time, that doesn't make it a quantum computer.

[@johnessien3578]

It is parallel processing but on a much much greater scale. For example a 20 qubit quantum computer could perform 2^20 calculations at the same time. Currently it is impossible to build ones that can reliably perform with more than about a 100 qubits but imagine we get to unlock the ability to build more advanced quantum computers.

[@icecream6256]

​@@johnessien3578how big is the differenfe between 2^20 to current consumer grade GPU parallelisation ?

[@sfllaw]

2²⁰ = 1048576. In 2024, the biggest processors have 96 cores. It’s not a 1:1 comparison, but every additional qbit doubles the parallelism so the numbers get very big very fast.

[@johnessien3578]

​​@@icecream6256currently there isn't a quantum computer that can perform calculations that can't be done with classical supercomputers. That said, current quantum computers will outperform your high end commercial GPUs by 10s of magnitude. The technology is still in experimental and theoretical stage though, as there isn't a reliable way to deal with noise and interference caused by the quantum decoherence with the environment YET, amongst other issues. The vision though is that quantum computers could one day provide more powerful computing than anything our computers today can be capable of in a way that is more cost effective and scalable in the future.

[@chrisbonney7563]

I love Hannah's videos and thoroughly appreciate how brilliant and knowledgeable she is; however after watching I still do not understand the mechanisms by which quantum computers are so different from normal computers. E.g. binary computers have two states, quantum has two states plus another state, so that infers based 3 instead of base 2, why is that so insanely different?

[@ekananda9591]

Because of superposition, a quantum computer can explore many solutions at once. This is fundamentally different from classical computers, which must check each possibility one at a time

[@noone-ld7pt]

You are making the common mistake of thinking of the superposition as just another state like 1 or 0. That would, like you said, just be a base 3 computer, of which many have been built btw, they're just not a meaningful improvement on base 2 systems and require much more complex transistors so they are actually worse. Superposition on the other hand is a fluid range of infinite states between 0 and 1. It's not just the entire range of numbers between 0 and 1 though and the entire explanation is a bit complicated, but if you're interested in the technical definition then a a qubit is typically mathematically written as ∣ψ⟩=α∣0⟩+β∣1⟩ and must satisfy the the normalization condition of |α|^2+|β|^2 = 1 where α and β are complex numbers.

[@paulpopaul]

Amazing content ! Thanks for sharing this video

[@Openskylook]

Quantum computing is next nuclear fusion reactors and next room temperature superconductors. You know what I mean.

[@human_shaped]

This is very misleading, post-quantum cryptography (ie quantum-safe) has been around for a while and even has new standards based around it. To say quantum computing breaks all encryption is just incredibly ignorant or misleading.

[@mandydone3061]

Wow, really amazing documentary

[@pjacobsen1000]

9:55 "China has invested $15 billion, more than any other country". But the IBM guy just said that they alone have invested $7 billion, so perhaps this only counts state funds?

[@jakethomas6123]

Thank you for the video. However, a key detail was omitted: even though a quantum computer can consider all combinations at once (maybe), the combination you actually observe is randomly chosen. No one has yet proven a quantum computer to be equivalent to a Non-Deterministic Turing Machine.

[@Vikas-tp3wl]

6:10 this is the internet Jen.

[@paulct91]

What 'Race'? They are still quite a few years away, and very hard to build if some high volume and reasonably priced actual useful day-to-day consumer use case is found that can't be done with 'regular' non-Quantum computers. Basically that's one of the two key issues (among many others), difficulty in manufacturing and use cases (that can't ALREADY be done today without them).

Come talk to me when quantum computers are actually cheap enough and powerful enough to do things that regular computers can do. We aren't there yet. This is hype backed up with no evidence.

[@rohan.fernando]

Quantum cryptographic comms for interbank data security has been around for 20+ years. As for quantum computing, there is absolutely no question that this tech will develop to radically advance the capabilities of intelligence, however that intelligence will probably not be operating on biological technology.

[@beginnereasy]

[@lloyd3404]

Quantum security: I'm nowhere near as qualified as Hannah Fry ... maybe my limit would be making her a coffee. However I understand that some time ago scientists were considering the value of quantum bits in superposition as part of a security measure (for certain purposes) ... basically a particle in superposition will, when read, leave that state to a fixed alternative (spin value). So if the recipient of a secure transmission that includes a particle that is in superposition but is no longer in that state, then it may be evident that the transmission has been compromised. So Hannah: would you like your coffee black or white? There's an example: if it was made for delivery as black but arrives as white, then it's been compromised.

[@bojoneuwong-z8g]

Hannah is such a beautiful red head. I love her

Besides hardware you need a software. And without software it's like a rock. Looking on evolution of PC software over decades, even if someone makes working useful qu-mputer it will take a lot to develop new algorhitms and software side.....

01001 in superposition must be 10110 then given this whenever measurement occurred at 01001 then there always be 10110 so how this will solve our slow software problem?

[@alexandersalois7948]

This is not how quantum computing works. There are no 1 or 0 every bit is both

[@NLPprompter]

@@alexandersalois7948 that is my question... tp show some letter it has to... here an example : The binary number 01000001 represents the decimal number 65. When interpreted using the ASCII encoding, this corresponds to the character 'A'. So, if a computer is given 01000001 and it's interpreting it as ASCII, it will represent the letter A. and the opposite of that The binary number 10111110 represents the decimal number 190. In the extended ASCII table, this corresponds to the character ¾ (three-quarters). So, if a computer is given 10111110 and interprets it as an extended ASCII value, it will represent the ¾ symbol.

[@NLPprompter]

@@alexandersalois7948that is my question, so how does it even can work? here is example, she told us a qubit is 1 and 0 at the same time so... today software are something like this : The binary number 10111110 represents the decimal number 190. In the extended ASCII table, this corresponds to the character ¾ (three-quarters).
