B Quantum computing uses

  1. Jan 4, 2017 #1
    With the development of quantum computing, just how much could it improve our lives. Obviously faster computing, but could we begin to do things than conventional computer can't?

    The prospects of quantum computing seem to be very limited. There are some types of problems for which it is very much faster than regular computers and many more for which it is likely slower.

    It is NOT in general "faster computing" for all algorithms.

    If a qubit is both 1 and 2 at the same time, how would this not result in generally faster computing?

    I don't know enough to answer that but it's more complicated than you think. There are numerous threads here on PF about quantum computing. I suggest a forum search. As always, a good place to start is with the links at the bottom of the thread.

    thanks for the suggestion!

    Doesn't change the answer. Quantum superposition does not mean the qubit has both values at the same time.

    This from Scott Aaronson is worth reading. It's a cartoon, yes, but the points it makes about quantum computing are valid (Aaronson is a well-known expert in the field).
