Quantum computer

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 qbits, which exist in a supposition of all its possible states instead of a definite 1 or 0 value as normal bits do. Theoretically, 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.
