Quantum computers: IBM on verge of creating machine faster than any supercomputer: "WHY QUANTUM COMPUTING COULD CHANGE THE WORLD FOREVER: The most basic piece of information that a typical computer understands is a bit. Much like a light that can be switched on or off, a bit can have only one of two values: ‘1’ or ‘0’. Qubits – or quantum bits – can hold a value of ‘1’ or ‘0’ as well as both values at the same time.
This is what allows quantum computers to perform millions of calculations at once. While current computers can calculate very rapidly, they can only perform a limited number of calculations at the same time. A fully functioning quantum computer could perform millions at the same time. It would instantly be the most powerful computing device ever created by mankind."
