Quantum Computers - A Brief Introduction to Quantum Computing

In one type of quantum computation, enormous numbers of different computations taking place simultaneously can affect each other. This is known as quantum parallelism. It makes some intuitively very complex things simple end quote. Later on he goes on to explain how quantum computers actually work. He says a quantum computer with only a few hundred qubits could perform far more computations in parallel than there are atoms in the visible universe.
