I usually watch your videos to learn about new concepts and ideas in fields completely unrelated to what I do, so this is the first time I actually watched a topic on something related to my field of study and work (Computer Engineering). And it has been such a great experience to see how elegantly you guys approached some of the concepts I've been trying to explain family and friends many times (because the question "so what exactly do you do?" or "how do computers actually work?" naturally pop). This gave me a very unique perspective on how much "simplification" is actually done on the subject to fit in a video, and how accurately and brilliantly the essence of the topic is captured. I already had a great level of respect for all the hard work that's being put in these videos, but it just went to the next level. Thanks for all the awesome work in educating the world.

My professor in Computer architecture is doing research on quantum computers, and he said to us today that Google and IBM promise more than they actually know. He believes that it will take several decades to be able to use them really well and even then not in the sense of a private computer, but rather in large projects.

Hmm, well, while it's definitely true that we're definitely still a few decades away from being able to do something like Schor's algorithm, I feel that's a bit cyncial. They've definitely made some absolutely remarkable progress. The current best is 127 "qubits". Those qubits are too unstable to even as much as all connect with each other with CNOT gates so that's in practice 0 qubits *but* ; it's definitely a lot further than I would have believed possible within a decade, 5 years ago. Suddenly; to me, the magical ~1000 qubits we'd need to have an *actual, useable, stable* 1-bit quantum computer, seems like it's within reach. And to me, that's absolutely astounding.

A transistor only have 2 state : on (have electricity, or electron flow through it), or off (do not have electron flow through it). The flow of the electricity on transistor could be controlled, flip on and off by a small current on its base. So, only a few atoms and a lot of accuracy could be enough for a transitor.

@Ignacio Benavides Eventually you have to switch to higher frequency lasers because you can only focus a beam of light down so far before diffraction takes over and makes it unfocused again even if your optics are focusing it to a smaller point. I forget exactly what causes the diffraction, but I know that a higher frequency beam of light can be focused to a smaller point because it's not as effected by diffraction. Right now they're working with pretty "hard" (aka high frequency) UV light. They could switch to X rays I suppose, but we have problems making lenses that work at that light frequency. And that's why it's so hard to make a single atom transistor (of course the name "single atom tranistor" is a bit of a lie anyways, it's not just "one atom is magically a transistor", there's a bunch of other atoms around it to form the gates and stuff.

Have you ever thought about the impact on machine learning where you can try every possible weight combination in a short amount of time and therefore get an PERFECT Function Approximation. This would lead to perfect neural networks who never make a simple mistake and can learn from a ton of data within a millisecond to get the global minima. That would lead to an extreme AI revolution!

I still have a hard time believing that quantum computing would ever work. Representing lots of states at once sounds good but im reality you're bound to run into precision problems. The good thing about traditional computer is that they have built in room for errors so, if the electrical current is a bit too high or too low, it is still rounded into 0 or 1, or a fault is detected. How can you detect an error in a superposition if 2^50 states?

Quantum computing don't really hold more information than regular computers; it's a bit unfortunate that Kurzgesagt propagates that myth. It's better to think of Quantum computers as an evolution of a Probabilistic computer, which is something we have plenty available in the classical setting; think, with some randomnizer, have input of 0 with probability A, and 1 with probability 1-A. The set of "superpositions" ends up being just the set of different combinations of probabilities - this ends up being large, in fact, infinitely large, since A is a real number! And further, looking at several bits, the number of possibilities grows exponentially. But that isn't a problem. You did still accidentally bring up a good point though; current technology gives us very large errors on basic computations for quantum computers, which is a problem, since errors accumulate exponentially. However, this is something the very active research field of "Quantum Error Correction" hopes to solve; essentially, our objective is to have a set of "self-correcitng qubits", each consisting of their own set of qubits. The self-correcting qubits are able to reduce the error probabilities to something manageable. However, with our current best algorithms and current best tech to implement quantum computers, we'd need ~1000 regular qubits to construct even a single self-correcting qubit! IBM has recently produced a 127 (normal) qubit computer. They are aiming for 1000 normal qubits by 2025 (so is Google); once that barrier has been breached, we will have our first real, useable quantum computers, that don'T immediately collapse due to rappidly accumulating errors.

Considering that this video came out 6 years ago, Imagine how many private think tanks have had access to this technology for the past 10 years. In combination with advanced AI, what on Earth could happen if it ends up being used to control us instead of free us... AI + Quantum Computing = Machines that are 1 million times smarter and faster than us. Imagine having AI robotics that are connected to the same cloud service that could be remotely manipulated altogether. Scientist usually don't have a say in the final product when projects are privately funded. They usually work in compartmentalized departments and have no control over the overall projects like at GE and IBM. The battle of virtuous win-win Quantum AI vs. global domination Quantum. AI would come into play. I can only hope these intelligently designed machines do not fall from grace. Is it possible that they behind wiser than mankind who barely even knows His own Intelligent Designer?

This genuinely has worried me for years. There will be a time in our near future that we will have the fastest non quantum computers. I'm sure engineers can curve off some of Moores's law, but the end result is inevitable. What worries me is that I don't think we will solve the huge issues quantum computers have in time. Will this be the next big economic crash? We have to wait and see I suppose

I think that is a fair concern. However, since progress is exponential, even though we may not have many steps left we have a lot of computing power to go. And if computing power is at a point in which it is totally efficient than in terms of an economics standpoint, that is actually a good thing. And in terms of consumer goods I believe that marketing is perhaps more important than the actual computing power so I doubt there will be a large decline in sales. However you are right in the fact that we simply don’t know and the only way to know is to wait.

we're a long way from this happening. for example, your computer screen can only run at a limited speed which is most of the time is capable of 60hz, or 144hz. If you're a gamer you know what happens if your computer tries to run faster than this limit, most of the time it's lighting issues, or jittering. sure you could slow it down, and the game would no longer have those issues, but even with that you would need everything to be quantum compatible cpu, ram, gpu, motherboard. It would require all of those to have quantum physics or none of them would be able to keep up with one another like how ram loads temporary processes, like a tab of google, or rendering in a game, the cpu takes in that information, and sends actions to different parts of the computer, like to the gpu to display the action on screen, or the audio jack to play the sound that just happened in the game on the speaker, I could stretch this further but I've already done too much of that.

Quantum computers are not good at storing data. My prediction is in the future we will have quantum chips like a GPU, because they aren't better computers, they are only better at certain things, and storing data is not one of them because they deal with probabilities instead of certainties. While they are in every state at once, each state has different probabilities. For example, a single qubit might be 30% 0 and 70% 1. What this means is that when you measure it, 30% of the time it ends up as 0 and 70% of the time it ends up as 1. Doesn't seem very useful, right? Quantum computers can do things very fast, but they can never be 100% certain. What this means is that quantum computers excel at problems where you can check your answer very quickly. So quantum computers aren't really helpful for storing data, instead you take your classical data, do some magic quantum processing which is super fast that gives you quantum data, then you change the quantum data into classical data, which is probably correct. Then you test your classical data and if it is not correct, you try again until it is correct.

These are around our first quantum computers. Remember the fact the first electronic computer was massive and could barely run something like 100 times 50. Now look at what it’s become now. If that happens to quantum computers, and it becomes a average thing that all computers use, lag will never be thought of. And if there is a way found for them to be mass produced, they wouldn’t be rare so they wouldn’t be expensive. For around 300 dollars, you would be able to get something that is cable of holding master programing. Then, the world would become easier and easier, more and more is discovered. Since now nearly everyone has a computer that can load anything instantly, a lot of things will arise that haven’t been seen before since not everyone today can share their knowledge.

a tiny correction, the 14 nm is the gate feature length, therefore technically a transistor is quite bigger than 14 nm, but 14 nm is the smallest distance in the gate (between two nodes, I am note sure which two nodes), anyway this is a huge difference, since an atom size feature node, won't mean that the entire transistor is atom sized, but rather the smallest configurable part is atom sized (which mean your resolution is [close to] atom by atom, which is freaking cool ! (and is fundamentally different than the entire transistor being atom sized (basically three atoms (or four) may form a transistor but not a single atom, absolutely not (unless we discover a new king of atoms!

tip to whoever coded the simulation: when doing a physics update, you can do a ray cast from a moving object, then detect if it hit anything and act accordingly. this is helpful for detecting if an electron hit an atom thick wall.

Since this video has been released, transistors have decreased in size furthermore. An iPhone XS or later has a transistor size of 7 nm, which was pretty revolutionary since it was one of the only devices to be mass-produced with such an architecture. In the past year, however, 7 nm transistors are becoming more prevalent in PCs. In 2019, 5 nm technology has become commercialized, though not on a massive scale. Even now, Samsung has announced they plan to commercialize 3 nm technology. The important thing to note here is that we design these transistors often decades before they become commercial. For example, 10 nm technology was first designed in the 1980s before being created in 2002 and commercialized in 2016. Currently, the smallest transistor created is at 2.3 nm, which may signal that we are at an end for transistors, considering how the disparity between the size of created transistors and the size of commercialized transistors has diminished greatly. Currently, some major nanotech research firms have considered 14-angstrom transistors (14Å, one angstrom is 10^-10 meters, 1 ten-billionth), which is about half the width of a DNA helix, by around 2025. However, whether or not we will be able to actually realize this is up for debate for the reasons mentioned in this video.

@Tuxedo Productions Dude thanks for this. It's so frustrating seeing everyone just type a bunch of bullshit in the comments. I get Kurzgesagt tries to aim for the lowest common denominator and there are better channels for scientific discussion but it's still disappointing nonetheless. The fact you have two douchebags here saying "too long" and "I couldn't read all this" is awful. I can somewhat wrap my head around the concepts in this video but I _completely_ fail to understand why the fuck someone would fail to read something, then spend the time and energy expressing that they didn't read it. TL;DR You're awesome and thanks for having something to teach us (which should be why we're all here). If anyone's interested, one of the concepts being discussed in the video and in your comment is called Moore's Law.

It simply makes the quantum bits become both the values and with one quantum bit you can already store the information of 2 normal bits. But if you have more than one qubit, you can actually say 2 qubits can store the information of 4 normal bits. With 8 qubits you can already store 256 normal bits complex information. This is really a game changer.

This made me understand them less. How can you have multiple superpositions if superposition is every possible position at once? How can you re-measure a qubit? If you measure it it changes and if you measure it again would it not change again? How can you ever know if a qubit is read properly if it potentially collapses into any of all its possible states?

the first thing that come to my mind is, wouldnt a super position allow faster than light speed light transmission? and from there, wouldnt that allow a computer to theoretically store any information about you, including your memories, emotions thoughts and everything else and transmit that information instantly? that'd be instant teleportation right there, no need for bending space. Im kinda confused as to how this isnt a huge topic, as its really just thinking 2 steps ahead of "abusing" super position mechanics in theory.

I guess you are talking about entanglement. Well entanglement is indeed instant, but it does not send any information, so it does not offer faster than light communication. The reason is easy: your measurement outcome is random. You will just end up sending a bunch of 0's and 1's, indeed with strong correlation, but meaningless message.

@Pascal's Videos Of course its not. The point is super positions are instant no matter how far apart. The idea is that you could transmit information with a super position in theory, if you could store every possible piece of information within super positions instant travel should be possible. It is possible to store every possible information (even trajectory of neutrons, electrons, every molecule atom and any kind of cinetic, potential or thermal energy literally any piece of you) cause it's all pretty much made of energyl according to the string theory and as far as we know since the universe seems to be deterministic outsifde of quantum physics after all. If you could convert that energy into super positions then yea. Question is would your copy be be conscious i guess, information transmittion is the most likely to be possible i guess, followed by matter, followed by conscious beings. Kind of a scary paradox thought... If your copy would say "yea it worked im myself" could you even trust that? Kinda blows my mind we might never truly know.

@Giovanni César Amorim 9A #DigaNãoAKokiDeus it's simply a fictional expirement to demonstrate a specific situation where superposition is best represented. You're over here analyzing every little detail as if it is a real life experiement. Of course the car won't be dead and alive at the same time but thinking in quantum computing, that could would be alive and dead. That's why quantum computing or the idea of it doesn't work on normal classical computers and circuits. It's very fascinating how weird quantum computing is because a lot of it is based on the weird nature quantum has which leads to a lot of questions that we don't know. I'm not an expert on this so I don't know everything, but there are defending people more qualified that can answer and explain this in more depth if you search it up. But even so, those experts still can't answer some questions about some of the more in depth qualities of quantum. I took a class and some of the questions asked, the teachers did not know because no one has discovered the answers. Sorry about the rant, lol just got really excited about this.

@kirbydied Schrodinger's cat is, to be honest, a really dumb experiment, the cat won't be both dead and alive, it's either dead or alive, the only thing that in between those things is our doubt, not the actual thing. Also, the cat will be dead because the radioactive material will most likely release particles, killing the cat.

@Bro cheet To really observe them you need complicated equipment, that will mess with them anyway, so you can observe them indirectly, by checking output of the device. It's not like brains are magic, though, such device should collapse quantum probabilities on it's own, without human observer, which makes Schrödinger's thought experiment dubious, actually.
