    Quantum Computing

    Can some explain to me...
    Quantum Computing VS Classical computing works?


    properly..
    so a sane NON Physicist person can understand

    how tunneling effect works.


    I understood the idea of Schrodingers cat applying to super state and how it is able help Quantum computing.
    But what is proper classical
    N in binary is turned to M in binary????


    my head full of fuck
    i am confusers...

    I could get my brother to answer this for you, but he'd probably just end up telling you to fuck off. He's a pretty big dick IMHO.

    I kinda got my answers after GOOGLING A BIT! and asking a few diffrent ppl


    I can't explain quantum physics to you here, just the general concept of "why quantum computers are so great".
    A current computer can evaluate a function, say, calculate whether a number can be divided by 3. However, if you want to know which ones of the first 10100 numbers can be divided by 3, you've got to do the calculation 10100 times.
    The quantum computer does the calculation once, and yields all possible results all at the same time.
    Quantum computers won't take over the computer world as they have a very specific type of operation, namely calculating the same thing with a lot of different parameters very quickly; there is no real reason to use quantum computing for single calculations. However, combined with a normal computer it can solve difficult problems in very small times. Probably the most important application is factorization of large numbers, which is heavily used in modern cryptography.
    To my awareness, there are only 3 algorithms known for quantum computing:
    1. The Deutsch algorithm, which checks whether a function is constant. This one is pretty useless in practice, but serves well for educational purposes.
    2. Searching a database (in theory)
    3. Factoring numbers (they factorized 15)
    As you can see, there's still a lot of work to do, factoring 15 isn't that much of a possible application yet
    .
    BUT

    BUT


    BUT


    BUTT

    A binary register with N bits in the quantum computer can be in all the 2^N different states at the same time due to quantum magic.

    You still need to let the different states interfere with each to get an output, so it DOES NOT automatically solve NP-complete problems.
    O I DONT UNDERSTAND THIS QUANTUM MAGIC!!!!

    NO!
    i want to understand
    i likely never be never develop anything realated to quantum computers
    BUT
    THEY SOUND FUCKING INTERESTING!

    beats the whole notion of digital computers...
    i see the future...
    and its this well... to my knowledge it is..

    SIR SIR
    KIND SIR

    I knows you folks at mpgh are smart persons
    you should explain this to me..
    it would be helpful..
    i know i cant quantum mechanics from a few sentences of knowledge
    but desire to get the gist of it.

    Physorg was updates on advancements in quantum tech every once in a while, you might find it informative if not enlightening.

    hes asking a question to trick and piss off the one trying to answer.
    see, jetagay helping gourav, is going to put himself in gouravs trap.
    lets see how this goes. gurba will never stop trolling.

    kinda learned A LOT of things today...

    GOOGLE FTW~
    nothing in this thread has been useful so far..
    i have no YET lost hope in mpgh V_V but it might as well be getting there..



    I wanna learn Quantum Computing VIA Mass simplification
    (it ant gonna happen)

    Answering a question?
    trolling?

    WHY YOU BEING SILLY?
    (I wanna say retarded i have no desire to offend you)


    how is this trolling?
