Massively parallel classical logic via coherent dynamics of an ensemble of quantum systems with dispersion in size.

ABSTRACT: Quantum parallelism can be implemented on a classical ensemble of discrete level quantum systems. The nanosystems are not quite identical, and the ensemble represents their individual variability. An underlying Lie algebraic theory is developed using the closure of the algebra to demonstrate the parallel information processing at the level of the ensemble. The ensemble is addressed by a sequence of laser pulses. In the Heisenberg picture of quantum dynamics the coherence between the N levels of a given quantum system can be handled as an observable. Thereby there are N² logic variables per N level system. This is how massive parallelism is achieved in that there are N² potential outputs for a quantum system of N levels. The use of an
