New quantum computers - Potential and pitfalls | DW Documentary 

we need maaaaany many many qubits for that, and for all of them to be of good quality... its like the difference between 70s computers and todays computers, but on quantum we're still on the 70s

If we get to the mid 90s we good

​@@alvaroluffy1except now we have an assistance that wants us to create the biggest new house for them, and said assistance is already smarter than us (individually) in terms of knowledge since it can tap into all the digital documents

@@kyo250996 yeah of course it will be faster than 50 years, but still, maybe 10 from now, i think quantum computers are actually not the next step, but the next to the next, we're gonna have some major breakthrough this year or in a few years and that will keep us going for a few years more until when we crack quantum computers and probably nuclear fusion right around the same time, like, one or two years apart from each other or something like that and then will come another revolution

Hey that's how your brain works!

Must be refreshing working on such initiatives. Meanwhile most of us will continue living our sheep lives

​@@ForeheadPushUps i wish we could understand what exactly being sheep means, its somebody that "evaluate the opinions of ppl based on their authority" for example a person with a 1000 page book in his resume is considered more correct. We dont think logically to evaluate their opinions, in reality, from the appearance/authority/social position of them , we conclude the correctness and falesness of the statements. Sheep and sheperd ,they follow the sheperd even to the slaughter house. Knowing This one simple fact about sheepness can tchange whole lives and it doesnt need high IQ at all, all it needs is effort in going thru everything u know and start re evaluate them based on ur simple logic , common sense, it takes alittle time but it turns u into a beast of real thinker , this is why they say all humans have the same brain capability but 99% dont use it.

What about chine ? Ive heard the google , ibm can only run for seconds with 50% error rate but china more stable with less than 10% error rate? Have u heard about this ? Can u explain more about it ?

You too can work on something like that but you have to study hard.@@ForeheadPushUps

@@climate-moneymakingcampaig305 Idiocracy

What?

yep, technically, we humans invented portals technology

i guess...as they dont give detailed technical information... what they mean by standard computers cant do is floating point precission . ie defining and storing floating points numbers on pc takes lots of memory and lots of time to do computations on them. while i guess they use electron states as ram modules. therefore on traditional computer one precise floating number that requires lots of bytes while on quantum bit depending on precission it probably can store lots of mbytes of data only on one bit... im not sure just a guess .. if they can set and get value of qbit/electon state :D im not sure how they set electron state anyway if they can :D

@@ticiusarakan correct. It's literally a way to open so you can compute in an almost infinite number of branches of reality simultaneously that emerge into reality when the computation starts and collapse again when it ends - all in a split second. Mind blowing shit!

I'm going to use it to run SNES emulators.

Do you know DW stands for don't worry

Current trajectory is AI > Silicon Photonics > something else > Maybe Quantum computers. Not in our lifetimes for sure

​@@ChinchillaBONK in mine for sure

It never will. But I see some offload to photonic computing for some processing but never the complete replacement.

@@catchnkill photonic has a lot of potential

@@andrewreynolds912 Of course, but never complete replacement.

Thanks for watching and for your constructive feedback! :-)

🤥

No, it's about absolute control and the enslavement of the entire human race. Wake up!

Hi, thanks for asking! Some of our documentaries have been bought from other production companies and distributors and therefore have limited online rights. We hope that clarifies things. :)

Yes, but it's a failed thought experiment. It is a document of Schroedinger's confusion about quantum mechanics, though.

It was more an analogy, to explain the quantum effect by trying to compare it with something macro like that thought experiment. But it could never actually work like that

Yes, but cats love boxes anyway. They are simply letting us know that they've already licked quantum mechanics and are waiting for us to catch up to them.

For the record, the OP is talking about the segment at 6:16. After having seen it, I agree that DW's attempts at tongue-in-cheek humor there, "primarily known because of a cat", "an experiment that he fortunately never carried out in real life", rather falls flat on its face. 1) No, he is primarily known as one of the founders of quantum mechanics and for the Schrödinger equation. That's like saying that Einstein is primarily known for E = mc2 and for crazy hair, rather than for developing the theory of relativity. Granted, popular science vs. science, I guess. 2) Yes, I am afraid you are probably confusing your general audience by mixing up thought experiments with real experiments for the sake of a cheap joke there, DW. Still, thanks for the great documentary!

@@Irrazzo One can easily carry out Schroedinger's cat as a real experiment. Even at home. It will be just as pointless as it is as a Gedankenexperiment. The problem isn't Schroedinger. The real problem is that it's basically 100 years later and we are still not teaching modern physics in a rational way to the public. Everybody is focused on intellectual debris from the 1930s instead on handing out the correct explanations.

Ohhh the irony 😄

New word unlocked Techer: a person or institute who gives info about technology

What is wrong with that? This was told about Google and IBM - private companies, private investments and so - private risks and someone's profit. To make money you need to give people what they want, so companies doing their best to make progress.

Nothing wrong with that, right, except that these billions you will pay out of your pocket. This is not massive product, and heathcare is most unaffordable thing there, so tech from billioners for billioners. And if it will be successful *or not* you will pay these billions anyway "taxed" from other companies products...... your point is clear, but from these kind of videos, epic music, great intentions, they wanna say that's about saving planet, green energy transition, wonder of medicine, for humanity - but real point of this investment is take money out of your pocket. And simple example - some energy companies already charging "green energy *fee*"

"private companies, private investments and so - private risks and someone's profit." - and public payment from new subscriptions, fees, charges, bumping prices etc. No matter if tech will successful or not (while it could take decade(s)) and ton of money. Another points that they not collaborate but every company invest billions in their own project that we will pay off in any scenario

Long story short - many companies spending billions to create the same product, with questionable outcome and the main point astronomical tons experementing by money milked from the current end customers

@@rendermanpro This is called competition. According to your logic, we should only have Boeing, and developing Airbus was a mistake, we have iOS, so why have Windows, Linux, FreeBSD, SunOS, etc. The best will survive, we cannot foreseen which one is better. Money was made by companies that make those research, not milked, or invested by investors. If you don't like competition, look what happened with soviet economics, compared with the market one.

True

Just you wait for quantum developed ai... it will develop better quantum computers... which will develop better ai... which...

@@mrcookies409 LoL. Wake me up when these halcyon 'daze' arrive.

@@adroitspartan7907 By then it will be too late >.

quantum will be a tsunami compared to AI....when quantum and AI integrate it will be an entirely different world.

AI isn't advanced enough yet, tho it's rapidly evolving. What you think about AI now will be a whole different story in 12 months. Once we reach AGI level AI then you'll see what it's really capable of

How? 👀

It's not trained. Simplest quantum elements take inputs... each of which can be described as having a range of probabilities, and produce outputs of the same nature. A probability density function covers more possibilities than an equivalent digital 0 or 1. It makes no sense intuitively, but mathematically it's descriptive of the behaviour.

Well at some point you measure your system and results will be displayed somewhere. This is called qubit readout. It's quite mind bending to think that we can manipulate and sense objects on a quantum scale but we totally can!

To put the quantums in an certain state for computing.

Hi! I have a bit of background in both fields, so maybe I can give an answer. Ai and quantum computing are two exciting fields and often the two are used together without any good reason. Quantum computing is a novel way to tackle certian problems and it is not clear or obvious if it will be used to train better Ai, possibly in some distant future it might happen but it's too early to say. On the other hand, making qubits is quite complicated and it requires carefully tuning devices. In the future, where it would be impossible to manually tune thousand of qubits that might even "talk" to eachoter, Ai tech could be used to tackle this multi variable/parameter space that is very hard to envision for our brain but it's Ai (and machine learning) bread and butter. You could take a look at the Nature comm. open access paper published also by the professor of the video named "Machine learning enables completely automatic tuning of a quantum device faster than human experts"

AI is at infant stage while QCPU is an embryo. Wait 10yrs.

I copied and pasted your question into ChatGPT and here are the results: "Artificial Intelligence (AI) plays a significant role in the research and development of quantum computing. Here are several ways AI intersects with quantum computing: Algorithm Development: AI techniques, such as machine learning and optimization algorithms, are used to develop new quantum algorithms. These algorithms aim to solve specific problems efficiently on quantum computers, leveraging the unique properties of quantum mechanics. Quantum Machine Learning: Quantum computing can potentially enhance machine learning algorithms. Research is ongoing to explore how quantum computers can be used to speed up tasks such as training and inference in machine learning models. Quantum machine learning aims to develop algorithms that harness the power of quantum computers to solve machine learning problems more efficiently. Quantum-enhanced Optimization: Optimization is a fundamental task in AI, and quantum computing has the potential to provide speedups for certain optimization problems. AI techniques are applied to develop quantum algorithms that can optimize complex systems, improve resource allocation, and enhance decision-making processes. Simulation and Modeling: Quantum computers can be used to simulate quantum systems, which is valuable for understanding quantum phenomena and designing new materials with specific properties. AI techniques, such as neural networks, can be employed to analyze and interpret the results of quantum simulations, helping researchers gain insights into complex quantum systems. Error Correction and Noise Mitigation: Quantum computers are susceptible to errors caused by noise and decoherence. AI techniques are utilized to develop error correction codes and noise mitigation strategies that improve the reliability and performance of quantum computing systems. Overall, AI plays a crucial role in advancing the field of quantum computing by contributing to algorithm development, optimization, simulation, error correction, and other areas critical for realizing the potential of quantum computers. The synergy between AI and quantum computing is expected to drive innovation and accelerate progress in both fields."

boo

fair enough, the video kind of said more than that though.

Solving problems that today's computers can't fast enough.

yeah its fairly complicated, university courses are dedicated to that exact topic. so don't feel bad about it

It is the only way to truly resolve those crises. Far from being a distraction. It's the only real solution

Quantum computing has been "a thing" since the beginning of the universe. Every single proton, for instance, computes the proton mass, something we can't do with classical computing very well. Every hydrogen atom computes the entire spectrum of hydrogen to infinite precision. That's very cool. It's also very useless. The problem is to make useful quantum computers and that is still lacking. There are fundamental reasons why it may not amount to as much as the current hype predicts.

This is purely a scam.

@@lepidoptera9337 Well a proton just has a mass. It doesn't "compute" it. The very concept of computation refers to a being using a tool to calculate something. Quantum computing is just using qubits (like electrons or photons) to store information like a normal computer would with bits. I also don't think you really gave a reason that it won't live up to the hype you just said the technology is still in infancy.

I agree we don't know what may happen in the future. However, there are certain physical limits you run into when making computers as small as we're making them right now. This is in fact one of the reasons quantum computing has some buzz - because theoretically it could break through barriers that the typical modern transistor is running into. But the physical limitations quantum computers have is also many - finding methods to actually physically control electrons and contain them is one such limit, as well as operating these methods at room temperature.

@@adampullen3786 A proton is a quantum system and it does produce a measurable physical property called "mass" that is very hard to calculate classically from first principles. To somebody in the field of computing that's a calculation and it's a valid "benchmark" between classical and quantum systems, whether you like it or not. So is classical chaos, of course, which not even a quantum computer can calculate. That we both agree that nature doesn't actually calculate doesn't matter. That's just idle philosophy at the practical level.

Somebody didn't want to work

Hi! Laws of nature work in a counter intuitive way but we have a very good mathematical description for them and we can test the equations on these quantum systems and they totally work! In particular, the way you interact with quantum systems can be devided in two fields, quantum optics, where you use lasers to "talk" to your quantum objects and quantum transport, where you use currents to "talk" with them

@@SquashyPan Thank you for sharing your knowledge.

"Quanta" is just a semantic thing. It just is the root word in quantum mechanics - where quantum is actually the singular version. So not quite sure what you mean by "it hasn't been used since Planck." Though I agree the use of the word the way the reporter was using it sounds a bit odd, as most people would assign something to the word - as it just means smallest piece of something. So most people would say electrons, ions, photons, etc. instead of just saying quanta, however I think given the reporter is doing his best and isn't a scientist this is nit-picking. Like the whole "smaller than an atom" quote is just for effect. Obviously you don't "need" to go smaller than an atom - but we absolutely do. The most popular form of qubit at the moment is an electron, which is very much smaller than an atom.

No you won't be running GTA or crysis on a quantum computer anytime soon Quantum computing is what regular computer was in the 1930s and 40s Need a whole warehouse floor to run one

A few registers and a quantum alu is pretty much wat u got Difference is Quantum alu can operate on all registers (qbit) at the same time with different instructions

@@Clancydaenlightened It isn't really intended to replace small device-based computers, and also there is actually cloud access to quantum computers right now! Xanadu made one a couple years ago and you can program it online remotely. also.... did you just reply to yourself? Twice???

I think there were recent material breakthroughs to allow quantum effects to occur at room temperature

@@delatroy hope you're not referring to any of Ranga Dias' withdrawn (fraudulent) Nature papers?

Cloud access will solve it.

They said same thing about classical computers in the early days when they were bigger than whole rooms

Not all architectures need cryogenics. NV centers in diamond work at room temperature. So does photonics. Ironically, even "ultracold atoms" don't need cooling (at least in the classical sense). They use laser cooling, which is much easier, technically speaking

Thank scientists for science.*

qubits? well typically if you use electrons its only 3. Where the 3rd is just a superposition of either spin up or down. I will say there are other options such as photons, which can increase the spectrum of states they can exist in by taking into account phase, frequency, and intensity. But wouldn't say it's infinite as far as I'm aware.

If we want to, yes. But we have to want it.

not pharmaceutical drugs you won't... lol

Let's see!

Radioactive diamond batteries.

Indeed. I’d say 7 years before we start seeing multiple blockchains being cracked like an egg.
