Quantum Computers. Not like I'm five, but like I'm a software engineer who has a pretty decent understanding of how a classical turing machine works. I can't tell you how many times I've heard someone say "qubits are like bits except they don't have to be just 1 or 0" without providing any coherent explanation of how that's useful. I've also heard that they can try every possible solution to a problem. What I don't understand is how a programmer is supposed to determine the correct solution when their computer is out in some crazy multiverse. I guess what I want is some pseudo code for quantum software.

Qubit is physical random generator, which quickly oscillates between 0 and 1. It does that so quickly, so scientists must operate with probabilities to perform calculations. They create analog quantum computers, where right solutions are much more probable than wrong ones, then let system to figure them out, then sample solutions periodically.
