A beginner's guide to quantum computing | Shohini Ghose



A quantum computer isn’t just a more powerful version of the computers we use today; it’s something else entirely, based on emerging scientific understanding …

  1. Does the computer recognise the characteristics of the coin, which you don't? So you can win if some of your competitors opt out? Is that physics? Sniff.

  2. Bought yourself an ouija board..it has updated info.about time traveling.. An explanaciรณn..wow!! So realistic…

  3. The more I look into it, the parallels between this and cold fusion are hysterical. "It works, except we can't do it cold…. And that's the big thing we have to solve. "

  4. I can write a program on my computer to flip the coin heads 100 percent of the time…does this means my windows is turned to quantum computer, kind of scary

  5. Let's ask an audience of more than 200 people to randomly pick an integer between 0 and 1. Let's pretend that we are stupid enough to not be able to predict the average answer.

  6. I can't believe this stupid video that only mystifies QC has more than one million views. This is not an explanation of QC. This is an example of how Google algorithms can promote stupidity

  8. Let's try to make my current cell phone work first before we start making quantum computers๐Ÿ˜‚๐Ÿ˜‚๐Ÿ˜‚

  9. we need to stop using quantum computers on earth , we should start using them in actual space to get faster quantum computers using solar panels and dry batteries also the quantum computer will suck the super cold temperatures of space to work way faster and 100 % energy efficient and cost way cheaper to run this is a real quantum computer not slow old school way of using quantum computers , Long Live the FutureSpace Quantum Computers.

  10. Mmmm
    It's looks like you have to study some years to understand why a perfectly programmed quantum computer can always win the coin game or teletrasporting datas.
    10 minutes suits better for learning pancake recipe.

  11. Probability dont even work that way lol. When head and tail has only two side doesnt mean you will get 50 heads and 50 tails in a 100 flips. It only means you will get 50% chance to get head and 50% to get tail. Wrong!

  12. Hi , future people.
    I knew you will come back to this classic computer to check your innovation's past.
    Just don't forget that we have gems called memes, preserve them, they are very precious.

  13. If human intelligence is 1's and 0's, the qbit is 1/0 combined is God intelligence; don't you think it will win every time??

  14. Is the given example just a metaphor? I mean what would be the possible outcome if the conditions were reversed (Head = Human Wins, Tail = Computer Wins)? How the probability distribution of two eigenstates are calculated in this specific example?

  15. 1. You choose a side
    2. Computer choose a side
    3. You flip a coin physically and get the result
    4. The computer wins almost 100% of the flips. I don't think so.

  16. With that technology hackers would also adapt new ways to secretly control other devices if you agree like means yes and comments means no๐Ÿ‘‡๐Ÿ‘‡๐Ÿ‘‡๐Ÿ‘‡๐Ÿ‘‡๐Ÿ‘‡๐Ÿ‘‡

  17. I have a task for a quantum computer. The monitor can display the entire universe, we can look at other civilizations, and I have the task, find all the images combined into one.

    In this film we see each other and maybe we are ashamed of our stupidity.

  18. I am certainly a fan of science but this is just weird. If the human player flips the coin and if the result remains unknown how can the machine (quantum machine) undo the result in its favour. And why were there operational errors? If you think about the first example, message encryption, 3% failure rate due to "operational errors" would be quite disturbing.

  19. Yeah, let's use computers as a crutch — Let the computer do everything. Let a computer do something as simple as turning a light on instead of you flipping the switch. Then people will just end up like those fat blobs in the movie, Wall-E.

  20. Very interesting & helpful explanation about Quantum Physics ๐Ÿ™โ˜ฎ๏ธ
    Thank you & Congratulations for the Young Girl Quantum Physicists, me like your Parents are very proud of you,long and prosper life for you โ˜ฎ๏ธ๐Ÿ™
