Quantum computer
From Just Solve the File Format Problem
A quantum computer is a computer making use of quantum physics phenomena. They are currently in the experimental stage. Instead of bits (binary digits), quantum computers have what is known as qubits, which exist in a superposition of all its possible states instead of a definite 1 or 0 value as normal bits do. Theoretically, some very complex problems which would require prohibitive amounts of computer time on normal computers could be solved quickly as the quantum logic simultaneously explores a huge range of possible states.
