Dope Tech Episode 2

<<@osxoep8847 says : A few things on quantum computing works for anyone looking to go a bit more in depth: - Qubits aren't exactly 1, 0, or both. It's more accurate to say they're 1, 0, or a linear combination of 0 and 1. For example a qubit can be in the state |x> = a|0> + b |1> where |a|^2 + |b|^2 = 1. We write quantum states with this |> notation. - When qubits are measured, all we see is a 0 or 1 for each qubit. The quantum information stays inside the quantum computer. - Other models of quantum computers include Ion Traps, Neutral Atoms, and Nitrogen Vacancy Centers. - We understand some algorithms that give us exponential speedup vs classical algorithms. The problem is our current devices are noisy - they have errors. - We are trying to make qubits with fewer errors and also make more qubits. Once we reach a certain level of qubit error, we are able to combine many qubits together to perform error correction. (this is called the quantum threshold theorem) - In the meantime, some research groups are looking at algorithms that don't require a lot of error correction and can run on near term quantum computers. If anyone has questions, I can try answer in the comments. Source: I work for a quantum computing company. Bonus: superposition and entanglement isn't enough for "quantum supremacy", you need additional types of operations to get the speedup (Gottesman–Knill theorem). I think most of the hardware companies mentioned have implemented or are working at implementing the additional operation so no need to worry :)>> <<@mihailvormittag6211 says : 👍>> <<@briankleinschmidt3664 says : All of those companies have insane stock prices - the ones that are public companies. I was going to invest in QC, but there was no access.>> <<@theuniverse9338 says : 8 26>> <<@theuniverse9338 says : *Please for god's sake tell me is quantum physics is high temperature or low temperature theory??*>> <<@protonneutron9046 says : there won't be a commercial "quantum computer" for at LEAST 15-20 more years if even then. I'll bet you 100 quid. (save this post 'till '37 )>> <<@ZFlyingVLover says : If a qbit can be 1 or 0 or both then HOW is that information useful for calculations? Thats fine if you calculate based on 1 , then recalculate based on 0 but you cannot calculate based on both. wtf>> <<@TentaclePentacle says : What you call quantum computer it's nothing more than a ternary computer system.>> <<@anmolanand1213 says : I wonder how many times did he say the word "quantum">> <<@waynestewart1919 says : It would seem that photonic quantum computers would be the most practical architecture to develop. As, or so it seems, to be significantly more power efficient than cryogenic cooling solutions. These systems tend to consume 1 or more megawatts of power. And if they have any similarities with modern LEDs, they might consume as little as a mid-ranged graphics card or CPU.>> <<@snowglider400 says : I disliked>> <<@Alex1891 says : Did you rip your original explanation of quantum computers from YouTube for this video?>> <<@n1xx_gg says : Today's pioneers are companies not a single person anymore>> <<@link6563 says : Trusting China..>> <<@999calirage says : Remember once i did acid and i seen 0's and 1's all over my skin then years later i find out about Bits and quantum stuff blows my mind everytime i see 0's and 1's now lmao Idk wtf that means but yeaa life is def deeper then what we see 😂>> <<@GednilsonFreitas says : tank's for job.>> <<@songting6932 says : Oh later US will again claim China stole their technology and use all means to try to delay this technology for mankind using their national security as a fake front... just like the 5G tech and how they banned Huawei.>> <<@rgaleny says : CREATE A Q DESIGN COMPUTER, THEN ASK IT TO SOLVE IT'S OWN DESIGN PROBLEMS>> <<@beppeadr says : October 2021 Jiuzhang 2.0 - 113 Qbit>> <<@chubaka_4400 says : Sounds like cubits is the new transistor, at first they invented one transistor the size of a cherry, by now they can fit 100 billion transistors into one penny!>> <<@ukpoetry says : Now talk to all the algorithms that are not possible with such an architecture. *D-d-don't believe the hype*>> <<@paulc1614 says : I spend a lot of time studying fields that I've never been involved in. I enjoy cosmology, electricity, physics, mathematics, and by trade am an aerospace engineer. This is the first video to actually blow my brain to pieces lol. Thank you for giving me a new subject to dive into as I am woefully ignorant to this one.>> <<@cokeforever says : you should do a "fall of websites" vid, pointing out how quality (social interaction) came above quantity>> <<@jedclampett6466 says : It's an electronic Ouija board.>> <<@johnnywilliams2641 says : https://www.youtube.com/watch?v=2UwEjxduHM0>> <<@h3rrpanzer88 says : What is the implication for gaming? Can't wait to see how it will be implemented in that field. Would this do away with separate needed graphics cards all together with just more system RAM needed?>> <<@loveluclins says : So IBM still wants to take over the world!>> <<@Adoblem says : love this channel, but wow that intro music is atrocious>> <<@ryanhocstetler says : Big love>> <<@yash1152 says : 5:17 interactions between classical and quantum systems>> <<@decentralizedtechnologygoa9426 says : I have thought of a laser CPU a long time ago I even told computer scientist about this and they thought I was crazy and I have thought of a quantum entanglement internet using quantum entanglement as itself as a data transfer I have dyslexia I had hydrocephalus when I was born and I was abused and still in being abused to this day just think if I didn't have these problems what I could actually do>> <<@colinbutts252 says : Dave: "Open the pod bay doors, Hal!" Hal (IBM): "I'm sorry Dave. I'm afraid I can't do that." https://www.youtube.com/watch?v=Lcu_Bss_n4E>> <<@CharlesVanNoland says : We just need graphene semiconductor based integrated circuits - way less resistance means way less power means way less heat and way faster switching speeds. Instead of barely being able to hit 5ghz we'd be able to get 50ghz compute cycles and even with yesteryear's transistor sizes (i.e. 2010 transistor sizes) that'd still be a huge leap in compute speed. GRAPHENE!!!!!>> <<@arcadealchemist says : when we get photonic gate computer blades like in star trek ;)>> <<@theFLCLguy says : We still have not ran any software on it. We don't have any evidence it's even possible. It's all purely theoretical. And even if it's possible it can't scale up enough to compete with classical computing. This is because ALL quantum physics is theoretical.>> <<@sayingnigromakesyoutubecry2647 says : It's amazing. Imagine all the complicated physics problems that have many differential equations (like a hundred or so) being easily solved. Imagine designing a car or bike with such a high level of simulation. Even something like IA - evolutive solutions to something as simple as a wheel. We will see massive advancements in all fields of engineering... But since I'm a mechanical one, I can't stop thinking about this field. Even internal combustion engines with significatively better gas consumption.>> <<@lukiepoole9254 says : More pseudoscience. This world has really fallen deep in the BS hole.>> <<@rabokarabekian409 says : DARPA = Defense Advanced Research Projects Agency, "Ok it works, how can we use it to kill and destroy?">> <<@Mike-tv9rk says : Chris, promise me that you wont let Microsoft gain the monopoly on Quantum computing. I Already have to enter a Quantum state to locate any of my files nowadays . And my daughters Minecraft Bedrock and Java account passwords are regularly in a superposition !>> <<@isthatyougary says : Thanks!>> <<@AndersonEvans says : No trapped ion, U of Maryland, IONQ mention?>> <<@grantjohnston7148 says : I really is unbelievably unbelievable how Canada not only developed the Quantum computer in Toronto, Google brain, they also developed NORAD system and technologies, the five eyes systems and technologies, Leopard 2 tanks with Canadian technologies as the most PRECISE killing machine on earth, invisibility suit and blankets technologies, massive cyber technologies well beyond any other nation, Or even small group of Nations. While NORAD, And the five eyes systems and technologies are going on 50 years old now ! And still cutting edge technologies today !! Unbelievably unbelievable is an understatement !>> <<@christiand.3348 says : I am wondering, why IQM is not mentioned in the list of pioneers, as they are working at the forefront of Quantum Computing.>> <<@SurfinScientist says : I don't hold my breath.>> <<@Neffins says : I can't believe you didn't mention AMD here with their recent patent.>> <<@nightmisterio says : I think QC are a scam, a gimmick to pump stock prices. Super Position and Entanglement are miss conceptions errors of physics, so they must not mean the same in reality in QC, how can more actions to reach a value be ever more fast than a normal computer? They probably will use specific cups like they do using Cuda cores and use AI algorithms to speed up tasks. China? Imagine one day they use all the backdoors they been implanting in encryption and hardware and then they will claim it was cracked by QC, what prepared answer will they have for us then?>> <<@TunnelSnake-es7tu says : And there was no more traffic in 2030>> <<@philipmcdonagh1094 says : It will be Intel all over again. Drip feed us a faster quantum processor every year for 20 years when they already have the next few generation's on the shelf, just to make money. I don't know much about this sort of computer are we heading down the road of machines solving problems themselves. Something disturbing about a computer giving you an answer to a question you haven't asked it. Now I see why Einstein called it spooky action.>> <<@RichGoodDivineAdventures says : Still nothing new. Quantum computing is far easier than this.>> <<@JonathanARae says : Very boring presentation with little practical explanations>>
