Quantum finite automaton

A quantum finite automaton (QFA) is a type of machine that can solve complicated problems by making use of the laws of quantum mechanics. It works like a regular finite automaton (like a computer program) but it can exploit quantum effects like superposition and entanglement. Basically, it can look at a bunch of bits (like 0s and 1s) in multiple ways at the same time, so it can finish the problem faster.
