    He never even explained how the Q computer finds the Queen faster than the classical computer. I.e the normal computer tries all possibilities one after another until it finds the queen. The q computer is supposed to try all possibilities at once.

    The problem with explaining anything that has positive and negative values is that their is no such animal in the universe. All things and forces are comparable and not positive nor negative The Sun is the largest mass and it is only comparable to the Earth as a matter of mass, Its magnetic field is likewise greater in scope than Earth’s. At the same time Jupiter is larger than Earth and in both descriptions it is larger by comparison, mass and magnetic field as well as a gravitational attractive force. All actions, events and operations act on the comparative nature of the two or more bodies in question. We are influenced by both the Sun and Jupiter as to our comparative values rather than a positive or negative state. Our Moon is affected by the Gravity of the Sun, the gravity of Jupiter and the gravity of the Earth in a comparative way based on the distances apart of all of the objects in question. This is why the Moon’s angle on our plane is different and the Moon’s distance from Earth is increasing while at the same time the Moon is in a synchronous orbit, almost, with Earth. In the three or more billion years we have been companions, based exclusively on our gravity the Moon should be orbiting on our plane and have a stable distance from Earth and be exactly synchronous in its orbit at very nearly zero eccentricity.

    the reason this is 100% silly is that it would need an equal number of analog cables, that is why they stop at 5, it is a really low number, I mean, why not 9 cubits IBM?………..and then 50 is right around the corner, the time is NOW !!!!????



  4. Gold Spot on January 19, 2020 at 8:45 pm

    Fake views number. One million people watched this boring talk. Lies.

    # of TED views are manufactured.

    Silly talk. Makes no sense. On purpose.

    Who says life starts from underwater volcanoes? Lying paid and bought scientists.

    If you can’t solve a chemical formula which supposedly forms life, without using a computer, what do we really know? Nothing.



  5. Earl Washington on January 19, 2020 at 8:46 pm

    think about the power of this presentation had it been delivered in English.



  6. Abi on January 19, 2020 at 8:46 pm

    What logic did you use to find the queen using the two-qubit quantum computer exactly? Anyone kindly tell me



  7. Russ Claeyborn on January 19, 2020 at 8:46 pm

    Great… just like how the evolutionists in the 19th century explained cells with gelatin , today, they’re explaining quantum computing with a deck of cards.



  8. Pam Tufts on January 19, 2020 at 8:51 pm

    Quantum computers just use Schrodinger’s cat to turn the cards over for you…



  9. Mitchell Glaser on January 19, 2020 at 8:52 pm

    There is a slide in his presentation that explains how a quantum computer would solve the card problem, but he skips that slide – you see part of it for a moment though at 6:28. Could someone please show us that slide? Otherwise this is nothing but clickbait.



  10. Old-Man Logan 000 on January 19, 2020 at 8:54 pm

    Written version please 🤔



  11. Toni Widjaja on January 19, 2020 at 8:54 pm

    I learn 3 things: (1) nature is quantum machanical (even though I sorta learn this in school decades ago I have completely forgotten about it), (2) quantum computing is vastly more powerful than classical computing (‘hard problems’ is another blast from the past) , (3) quantum computing is currently in the mainframe stage of classical computers and it will become mainstream in my lifetime, and I better understand it at least a little bit.



  12. Greg Black on January 19, 2020 at 8:55 pm

    I’ve reported it as misleading rubbish. Hopefully it will be removed.



  13. Andrew Bell on January 19, 2020 at 8:55 pm

    Dario Gil knows so much more about quantum computing, mathematics, scientific notation,
    probability, and chemistry than
    the avetage dude, that even if he tried to explain something to us in an easy to understand manner, what he would say would still be so far over our heads that few of us would get it. That doesn’t mean that he didn’t say something important here, and pretty clearly.
    You could, if you haven’t done your homework, start doing it. You could get a science book and look up how to do scientific notation.
    You could read a book by Feynman. You could take a course in chemistry. You could take a course in coding. You could read some articles about quantum computing in Scientific American or some other publication. You could do more research on the net, say at Curiousity Stream etc. and watch other similar videos. Dario Gil is not yo mama. He isn’t going to make the cutting edge research science behind quantum computing easy to understand, and "clear as an azure sky in deepest summer" in a ten minute video. He’s not explaining the rules of checkers, or reporting the scores of a football or basketball game. This is cutting edge physics, and way more complicated!



  14. TheblackNight on January 19, 2020 at 8:55 pm

    Is it normal that this scares me? Just think about what horrible things people could do and how good people are at using new inventions to do horrible things..



  15. S. VC on January 19, 2020 at 8:57 pm

    Out of the 15+ min of the presentation no explanation has been given, but rather an unsufferable quote and a pledge.



  16. olivier l on January 19, 2020 at 8:58 pm

    blah blah and no explanaiton whatsoever…



  17. John Fink on January 19, 2020 at 9:03 pm

    you already have to know the answer to learn the answer, much like a quantum computer🤣

    Greetings from the inter-dimensional multiverse – I’m from the future!
    I’ve just traveled in time from the future to now which is the past present and future all happening at the same time through the formless self in the inter-dimensional multiverse, hello friends!
    ​https://youtu.be/rM8SN6RPkWQ

    Using quantum computing to navigate the inter-dimensional multiverse:
    The multiverse is real. Quantum computers, particle acceleration and microgravity hold the keys to unlocking inter-dimensional Multiverse time travel. I need to speak with leading research scientists in the fields of particle acceleration, quantum computing and AI to truly work on my theories. Please contact me, thank you very much! Sincerely, Benjamin Ogden coming from the past present and future.

    It is easy to understand the false perception that Unified Field Theory and Quantum Computing are at odds with each other. I suggest they are in fact entangled and that artificial intelligence and quantum computing hold the keys to proving a Unified Field Theory (one single theory) that completely describes an inter-dimensional multiverse reality of existence.

    All it lacks is clarity.



  20. jhon haller on January 19, 2020 at 9:08 pm

    It’s insane to listen, wow, how smart they are



  21. hipposelect on January 19, 2020 at 9:09 pm

    Glad I read the replies before watching this….then didn’t bother.



  22. Marijan Madunić on January 19, 2020 at 9:09 pm

    Trust me. As a teacher with 27 years of experience, I claim that this gentleman does not even understand what he is talking about. Anyone who understands a topic deeply can explain it quickly and successfully. Listeners can also immediately feel it, as if they were in the hands of an experienced fighter pilot and fully trusted.
    I tried very hard and couldn’t figure it out. very superficial and unclear.



  23. JAG 0937 EB on January 19, 2020 at 9:10 pm

    "quantum computer" is fucking nonsense



  24. gurbanliye on January 19, 2020 at 9:10 pm

    2020 and I am still searching YouTube for real quantum computer demonstration, yet YouTube algorithm gives me this.



  25. Aaron Nathanael on January 19, 2020 at 9:13 pm

    you will die from interworking with this demonic luciferic devices…
    these devices (also the qunatum computer) are used for demonic
    crystalline objectives… never for the humans soul purposes… BE AWARE
    OF THAT… The objective For lucifer behind all this , is to make a
    Digital prison to enslave our living and soulfull consiussness and build
    a new soulless and cold alpha matrix… only for the Crytalline
    conciusness… I hope these humans will realise these huge mistakes…
    in science…. everything is dead!! but in reality .. everything is
    alive and breathing… We you lie to yourself in that way you will also
    get cold and soulless.. like the scientist in silicon valley… Abused
    and enslaved to misleading horizons… the horizon that is build only
    for the godless… Soulless and senseless…



  26. Deckie Deckie on January 19, 2020 at 9:13 pm

    Mister…..The letter G in the word God…..sounds the same way it sounds in the word Gil….unless a hillbilly Phd moron changes it….to geewizzz



  27. Socrates Again on January 19, 2020 at 9:13 pm

    I just want the address to the "free" QC cloud site to hook up my computer with it.Stuck around waiting for this info. One in two chances of getting it by 16:34 : 0 or 1. I ended up: Nada, goose-egg, zilch, zed, etc., etc… Move on, folks. Nothing to see here…Be well.



  28. Nixon Rexzile on January 19, 2020 at 9:14 pm

    wtf is he talkign about, it’s like Nasa explaining Gravity which based on theory,



  29. Tomas Franco on January 19, 2020 at 9:14 pm

    if Quantum Computers run windows 10 we’re ruined for sure.



  30. cometmann on January 19, 2020 at 9:17 pm

    Computer, where’s the Queen? (computer asks quantum computer,which does the calculation, computer gets answer and says, "Here"). Thus 100% right, all the time.



  31. barabimas K on January 19, 2020 at 9:18 pm

    It’s a trick video they wanna see how many people actually know the difference between Classical computers (5) and quantum Computers(30000000000000000000000000000000) Fast.
    Now I forgot What i knew.

    So a quantum computer is just a raid system? First step is not to flip all cards.. You have to turn it on at least as step. You need to specify which drive specifially goes after which card. And so the computer labeling to into itself each bit and yeah any bit can be whatever character easily when fiber optics is used and it is only limited to how many colors can be recognized digitally. When regular.1 and 0 is a wire sending 1 a signal or 0 no signal. Halon collider . more like a giant loop of PS4s on a super cooled server loop..



  34. Nick King Televised on January 19, 2020 at 9:22 pm

    Can it play Minecraft?



  35. alsojuja on January 19, 2020 at 9:23 pm

    Just realize that in 20 years when they perfect quantum computing, scientists will be able to decrypt the files you’ve encrypted using today’s encryption technology.



  36. dav ep on January 19, 2020 at 9:23 pm

    You can find the Queen classically and of O(1):
    Lookup table:
    0000 — "invalid"
    0001 — Queen in slot 0.
    0010 — "" 1
    0100 — "" 2
    1000 — "" 3.
    Everything else –> invalid.



  37. Joy Anna Radcliffe on January 19, 2020 at 9:24 pm

    The quantum world is the atom and subatomic mystery of particles, and of wave function. On non- localitity, entanglement, tunneling, and duality of wave & particle function Also electricalmagnetic energy. Quanta: secrete packets, can travel faster than the speed of light. This made Albert Einstein bewildered and he called it spooky action at a distance. Quantum physics violated his theory of relativity.



  38. Sheikh Husain Timur Khan on January 19, 2020 at 9:25 pm

    why does stanford have to be included in every intellectual lecture. is stanford the stamp of authority for all things brilliant? bugger all !



  39. Omer Bin Abdul Aziz on January 19, 2020 at 9:26 pm

    Explained with a deck of cards? .. not really! Thank you for the comments everyone. Saved me some time – and I didn’t even need a quantum computer for that!



  40. the dude on January 19, 2020 at 9:26 pm

    I think this gives insight to the navy’s video on ufo from the Nimitz. This ufo actually went from air to underwater with no disturbance in the water. So unlike what we know when we move thru space we move things out of the way like air molecules etc. for instance a boat will can cause a wave.but this ufo seems to move thru space by interacting with the air / water molecules. Almost like it is a paired electron and can change instantly like its pared partner. It doesn’t displace the water molecule it is thru the particle .



  41. DaSnipy on January 19, 2020 at 9:28 pm

    bull of quantum drops a big one here.



  42. Atomkey Sinclair on January 19, 2020 at 9:30 pm

    I don’t know about explain here. Perhaps describe by analogy of what can’t be done by traditional means would make more sense. If it was explained, it was in super-position.



  43. Calen Tanner Lightheart on January 19, 2020 at 9:33 pm

    He wants a quantum computer to explain the mythematics related to the non-existent nuclear atom, Fail:

    Much better short explanation here: https://www.youtube.com/watch?v=g_IaVepNDT4



  45. Dan V. on January 19, 2020 at 9:35 pm

    Wish I could sue my public school system for my inability to understand this. The jury would be too dumb and political to reach a right verdict. China will soon be able to come over and simply request that we get off their new country. Elon Musk would do well to create a floating country. No, wait, Learn Chinese Elon!



  46. Mitch Payson on January 19, 2020 at 9:35 pm

    explanation sounds like its just parallel machines. easy to understand.. now what makes it different than parallel



  47. mBabe on January 19, 2020 at 9:35 pm

    Justin Trudeau explained it better. Youtube it.



  48. Quamrul Hassan on January 19, 2020 at 9:36 pm

    FINEMAN IS A KNOWLEDGE VILLAIN. BECAUSE HE DISCOURAGED PEOPLE LIKE US ARE BEVERAGE. NOBELORIET FM SAID, IF U THINK U UNDERSTAND QUANTUM PHYSICS, U DON’T UNDERSTAND QUANTUM PHYSICS. SO ……..!!!!!!



  49. Henry Minsky on January 19, 2020 at 9:41 pm

    The Quantum computer can successfully get an investor to part with billions of dollars more efficiently than almost any other technology. That’s a rousing success. ….. for the guy getting the money anyway.
