    Judging from the thumbnail they are now using brass covered spiders.

    I’ve seen nothing that explains how QBits "compute". What is so magical about having these bits?

  5. Xi Le on March 4, 2019 at 1:14 am

    When Silicon chip reaches to the end, Quantum chip will be next. Will Quantum chip work in consumers’ computers or only work in the industrial computers like IBM? *Will Intel and AMD make Quantum chip into computers for consumers?*

  6. Richard Hand on March 4, 2019 at 1:15 am

    Oh by the way is that John Lenon’s brother???

    I just meant by one thing: When will I able to play solitaire on my next QC (Quantum Computer)?!

  8. jason curtis on March 4, 2019 at 1:17 am

    the government obviously have quantum computers 30 years ahead of this, all the time they catch hackers/deepweb marketplace owners some how decrypting data that would take hundreds of millions of years for a computer to crack. The insane technology that snowden released was just the tip of the iceberg, the fact that they are letting the public know about quantum computers means they already know everything about it. a quantum could hack launch codes for the entire world in nano seconds scary shit! if a civilian hacker got hold of one of these the entire world would be in his hands all money wiped, gas pipes stop working,planes cant fly just 1 of these computers could decrypt and re write the entire worlds software 124 bit encryption is like 1+1=2 for quantum comps :S im stoned and concerned lol only bad people will be interested in using these trying to pretend they are gonna use them for science the government thinks only in kill first do research later lol i bet trumps thinking awesome if someone tweets about my hair ill just make theyre nucular power plants have an "accident" JK fbi

    You guys won’t think this is so great when the robots take over, put you in the matrix and use you to computer Pi all day.

    Shouldn’t you be making two videos on this that we can watch at the same time? 🙂

    Quantum computers need big cooling system, so by year 2050 we’ll be seeing laptop with "Refrigerator Inside" instead of "Intel inside" label on it.

  14. psycronizer on March 4, 2019 at 1:22 am

    like the man said..it’s not going to blow anyone’s hair back until we get the machines available and practical, AND we have had a whole generation of kids geeking out over them…it’s totally different to any programming language or logic used in today’s machines, and that’s a whole new way of thinking, which means whole new ways to tackle things, a a whole new way of imagining ways to use it..my brains too old and set in it’s ways to start again, so bugger it.

  15. Trashcan on March 4, 2019 at 1:23 am

    Will it run Crysis?

  16. Strike Raid on March 4, 2019 at 1:23 am

    There is at least one working quantum computer in the government somewhere (probably NSA) and probably several. About a year ago, I saw a 12 character password on a zipped ‘national security’ issue file get cracked in about 3 or 4 days, and that includes all the time it took to do the paperwork, get authorizations (it was a US citizen) and whatnot. I imagine it was put in a queue of other jobs and was itself probably processed in a mater of minutes when it was finally worked (purely a guess though of course). And that was nearly a year ago, I imagine they have more and even better machines by now and there is no password that they can’t defeat if they decide to.

  17. Konrad Wycka on March 4, 2019 at 1:24 am

    So quantum computers can answer a question "what is meaning of life?"

  18. ste glover7 on March 4, 2019 at 1:24 am

    I wonder what they are hiding if they admit to a 50 qubit

  19. choppy thechimp on March 4, 2019 at 1:27 am

    I want a quantum bowl haircut

  20. Fernandes Fusion on March 4, 2019 at 1:27 am

    I have 1 question. This computers are great right .so can this computers make prof of god by computing ?

    Please don’t hate me

    Doesnt dwave have a 2000 qubits one now? Or 20,000

    Talking AI best used quantum computing,or simulation of multiple dreams vr ideas than exact and execute the single result with a classic set up, And/or go back to in any single classical decision and run it through a quantum set up at any point And back out to a classical set ,
    Say like when you are having a conversation you can to a conclusion a single conclusion after many decisions then you want to run that single conclusion back through many decisions again so and you can come to and even more efficient single decision and result for instance, It would be wise to be able to run any decision back into Quantum time setup and single classical set up to fix any mistake or decision change in the future.

  25. Michael Tarvin on March 4, 2019 at 1:39 am

    "Entanglement" a theoretical mythical unicorn fantasy similar to Hawking Radiation… quantum computing is extreme High tech masturbation hoping for spinoff technological innovations that can be monetized… similar to what happened during the space race…. it is the new search for the Higgs Bosun… Having said all of that I will also say that your video on the subject is the only one I have seen that is not all hype to appeal for some funding 😀

  26. Steve Gipps on March 4, 2019 at 1:41 am

    Rather than a smart arse comment: Thanks for this well prepared and presented informational video.

  27. Bob Lamb on March 4, 2019 at 1:42 am

    The addition of a third state of a bit really destroys the appeal of computers for me. I can’t abide maybe.

  28. Stephen P on March 4, 2019 at 1:43 am

    i am still not understanding how the brain does memory …. the physicist Roger Penrose thinks that the microtubules in the brain store memory in a quantum form ( this would mean that a low temperature isn’t necessary ) so my question is how come we don’t know where memory lays in the brains architecture ( unless it is quantum based ) and if it is then how come we don’t exploit this technology to produce memory circuits and quantum processors !??!?! i tell you why because big computing won’t be able to control it if we can grow our chips in a petri dish ….

  29. n/a on March 4, 2019 at 1:43 am

    nice summary

  30. Brad Mundie's on March 4, 2019 at 1:44 am

    Can it run crysis?

  31. Michael Tarvin on March 4, 2019 at 1:45 am

    Of note is that we can’t even use trit based computers for anything and we have been able to make them for 50 years.

  32. ShamanKish on March 4, 2019 at 1:46 am

    It is all about motivation.

  33. Mrb Drm on March 4, 2019 at 1:46 am

    in short
    its the best thing and no one can handle it.
    that’s why no one can give you any useful information.

  34. Modern Modern on March 4, 2019 at 1:48 am

    Solution; convert chip technology to quantum technology by conversion of single elements and functions into it; just do it! Implementing will be a super butcher! PS; your book is a butchers nightmare!

    It’s about making a smarter, faster, living,. AI. Because as humans we are flawed. Just wait and see.

  38. Mortimer Snurd on March 4, 2019 at 1:59 am

    Quantum computing will lead to transporters, replicators and fast interstellar travel

  39. Eric Lopez on March 4, 2019 at 2:00 am

    When will we have quantum drives for space ships?

  40. Donald Sleightholme on March 4, 2019 at 2:00 am

    i probably should defiantly of patented this idea but.. it’s a compass placed inside a inductor with a slight modification could maybe be used to represent 3bits or more instead of two bit binary and wouldn’t need liquid nitrogen to work 🧭 🤔😐😔

  41. ari vinza on March 4, 2019 at 2:02 am

    I will subscribe if you change your hair style

  42. Ken Heart on March 4, 2019 at 2:03 am

    Do you have a resource that explains how qubits actually WORK? It’s confusing, because it is the very point of a bit being 1 or 0 that makes computers function. Logic gates use this precise quality to make computers work. So how does a quantum computer actually use ‘smeared probabilities’ in any kind of functional mechanism? How do you code an ‘if – then’ statement with imprecise values?

  43. John Harbinger on March 4, 2019 at 2:03 am

    you can use quantum computers to simultaneously simulate millions of classical computers on a single chip eliminating the need for physical materials an manufacturing of classical computers. simulation is what quantum computers are best at.

  44. DowskiVision MagicalOracle on March 4, 2019 at 2:04 am

    Excellent summary, thank you! Quantum Supremacy sounds like some form of Qubit Fascism, however if they want to get there the Qubits will have to find some application in pornography.

    Can I just put it in the freezer?

    bristlecone makes me think of an artificial pineal gland

  47. jigga jaw on March 4, 2019 at 2:08 am

    I think this is one of those things where you just wait about 4 or 5 more years and check back. Last I heard their quantum computer was only about as powerful as a standard laptop. So at that rate (given the history of computers) in 4 or 5 years they’ll be way beyond the old silicon computers sure. But its going to be awhile. I await the day I can have a quantum desktop. Or an optical computer desktop. Either one is fine with me. Only one I don’t want is biological. I don’t think biological computing is something I ever really want to get into.

  48. Logic Lock on March 4, 2019 at 2:09 am

    great channel

  49. percussion 44 on March 4, 2019 at 2:09 am

    Sounds like a lot of hoop-la about something that has never accomplished anything and probably never will. Anyone seen a thorium car lately? Me neither.
