What's the big deal about Quantum Computers?

Well, they surpass ordinary computers in being ridiculously difficult to engineer.
But no. And no quantum computers will never replace regular ones. Binary logic works just fine for most things and is very easily implemented. Quantum computers are pretty much only going to be relegated to certain calculations. Maybe in the far future binary computers will have tiny quantum daughter boards to do that kind of math for them and then just use binary logic for normal operations, but that's far in the future, as today's quantum processors need to be supercooled to function properly. The real next leap in computer technology is light based computing that uses photons, because even consumer grade CPUs have hit the hard physical limits of what we can do with electrons. You'll notice that next-generation CPUs have gotten bigger than the standard form factor we've been using since the turn of the century, and that's because we literally can't miniaturize the circuit paths inside them any more than we have, because we've gotten to the point that if they packed the paths any closer together, electrons would be able to just randomly jump between them and short circuit them.

For a second there, I thought my Probability and Statistics class would make it any easier to understand. Well, that was definitely informative. As was

Lmao

Depends what you mean by quantum computer. Have quantum computational operations been carried out? Yes. Do we have a practical, functioning quantum computer? No. Do we know for sure that we'll be able to create one? No.

>Do we have a practical, functioning quantum computer? No.
what world do you live in?

you can literally buy one (if you have 15 million dollars)

How many Qbits do you get in a 15 megabuck computer these days?
