Quantum synchronization for classical distributed systems

Abstract

A quantum mechanical synchronization system for a classical distributed computing system. Einstein-Podolsky-Rosen links are established providing entangled photons to provide the quantum synchronization. In one embodiment, the system includes a laser oscillator pump, a spontaneous parametric down-conversion element coupled to the laser oscillator pump, the spontaneous parametric down-conversion element having a first optical output and a second optical output, a first photodetector coupled to the first optical output, a first clock coupled to the first photodetector, a second photodetector coupled to the second optical output by an optical link, and a second clock coupled to the second photodetector.
