The Origin of Quantum Information Technologies

In the 1960’s, Landauer argued that information must obey physical principles. What if information follows the rules of quantum mechanics? Feynman first proposed we could use a quantum system to simulate quantum mechanics exponentially faster. Deutsch later proved that the quantum computer is inherently more powerful. The field took off in 1994 after the discovery of the exponentially faster factoring quantum algorithm – an algorithm with with disruptive application in information security.
