Computer Hardware of the Future: Will the Classical-wave Simulated “Long Qubyte” Trump the True-quantum Qubit?

Abstract

Using the results of a recent earlier article, it is pointed out that homogeneously linear, strictly oscillatory, conservative classical dynamical systems that have N degrees of freedom automatically simulate N-state quantum systems. Because the simulating oscillatory classical system is not subject to the information-destroying constraints which are imposed on the simulated quantum system by its probability interpretation, that simulating classical system actually has a greater information-bearing capacity than the N-state quantum system which it simulates. In addition, it is easy to ensure that the simulating oscillatory classical system is robust against the “decoherence" problems which typically beset the simulated N-state quantum system. Though it therefore might seem tempting to classically simulate two-state quantum systems, namely the much-discussed qubits, it appears to be far more advantageous to use cavity electromagnetic standing-wave modes to simulate N-state quantum systems for which N is as large as possible. A single such cavity-mode simulated \long qubyte" might even suffice as the random access memory for an entire computer.
