How Does a Quantum Computer Work?

This video was supported by TechNYou:
A quantum computer works in a totally different way from a classical computer. Quantum bits or ‘qubits’ can exist in a superposition state of both zero and one simultaneously. This means that a set of two qubits can be in a superposition of four states, which therefore require four numbers to uniquely identify the state. So the amount of information stored in N qubits is two to the power of N classical bits.

    Super great!!! It couldn’t be clearer! Seriously!

  2. Pinecone Enthusiast says

    Is it basically just a Schrodingers electron?

  3. Mayukh Mukhopadhyay says

    How is a fuzzy logic different from qubit?

  6. Brigadier General says

    If quantum computers are not a replacement for classical computers, then why bother Investing billions in it ?

  8. Genesis gmail says

    Quantum computing will never replace our current computer tech. It will work with them but never replace!!

  9. Steve Kent says

    Chest hair at start looks gross.

  10. Abhishek Gupta says

    So basically it improves the big O for specific calculations where classical computers would be stuck in a potential infinity loop. That's what I could comprehend as a jist. Hope I'm not badly wrong though.

  11. Tuna says

    I understand and don't understand at the same time

  12. NASA limbu says


  13. William Burroughs says

    Well… That was as clear as mud.

    Quantum comuters and modern high-tech will be used for witchcraft; like in the old days they were called wise men, today's scientists are witches and warlocks (they are wiser than everyday men but use it for evil). Getting the forbidden fruit of the tree of the knowledge of good and evil!! Tapping into alternate realities that the antichrist has created (book of daniel: he will change times and laws – that is the laws of physics). That's what they do at Cern, too: they are opening the abyss and evil spirits are coming into our world… This is what the mark of the beast will be all about (book of revelations 13 and 14). With the micro needle array patch vaccine for covid19, they will inject quantum dots into the bloodstream (and artificial RNA), forever changing the DNA, doom the person to hell for eternity. This will allow people to access alternate realities but it will all be slavery to the antichrist. Be warned!! They are bulilding the new world order here and the antichrist will use this technology to enslave humanity, total surveillance and hunting down everyone who will refuse his mark and refuse to worship him. Do your own research. ABC of salvation: Admit that you are a sinner and repent, Believe in Jesus Christ as your Saivour who died for your sins on the cross, Confess this faith with your mouth.

    How does it work. Well it doesn't.

  16. Bailey Jorgensen says

    wait what

  17. Vladimir Lissoi says

    Thanks for dressing up for us

  18. Lavalambtron says

    But how can this computer make calculations with things that are yet undefined i.e. particles in a superposition? Are these waves collapsing into particles as it calculates but in a different reality or dimension?

  19. Anmol Singh says

    Now I want to study some physics and maths

  20. Pabnckn Cykma says

    So it can compute far difficult tasks than a normal computer but it needs a lot more time to do it, while normal a computer cant do it at all because of the complexity of the task.

    I want to know how many fps i cud get playing shadow of the tomb raider at 4k max settings on one of these

  22. Mapalo John Chanda says

    Fxxxxk y super position again
    Temperature increasing 😪😩🤕

  23. DownBlue says

    But can it run Crysis?

  24. Raveesh Mittal says

    amazing !!. Probably the best explanation of quantum computers in simplest words possible

  25. UniQuE TV says

    how exactly do they cancel out the wrong answers

    in quantum computing though?

  26. XII MM 1_Rifqi Maulana Jati says

    You understand and dont understand what does this video about at the same time

  27. Mo Was says

    Brain hurts my…

  28. flow with the universe says

    quantum computers are not faster. they just find the quickest solution to your problem. for example what is the quickest way to get some were or the best possible solution to a problem.
