Development of Chip-Based Optical Parametric Oscillators for Coherent Computing and Quantum Random Number Generation
Abstract
We propose to investigate and develop chip-based photonic devices for random number generation and computing applications. The devices will be based on the nonlinear optical process of degenerate four-wave mixing that will be implemented in microresonators using the integrated silicon-nitride (Si3N4) platform. By pumping the microresonator with two laser fields, an optical parametric oscillator is realized in which the generated signal is produced with a phase that randomly switches by pi every time the pump fields are turned on and off. This forms the basis for a random number generator that can operate at gigahertz rates and offers a potential solution for a wide range of problems that require the use of perfectly random numbers. By coupling such microresonators photonically the chip, the system forms a special network that can be used to solve non-deterministic polynomial (NP) time-hard problems. We will explore the dynamics of such a system and explore whether such a system has the potential to realize a scalable CMOS-compatible platform that utilizes the unique properties of light to solve challenging computational problems.
