Toward Scalable Quantum Photonic Engineering with OPO Networks
Abstract
Over the past few decades, overwhelming progress has been made on the demonstration of fundamental quantum phenomena. This has led to the implementation of small-scale quantum information systems in a variety of physical platforms including superconducting circuits and trapped ions. Despite these advances, a practically useful computer based on quantum phenomena that can outperform existing digital computers has not yet been realized due to the scalability and connectivity challenges tied to most of the physical systems currently being studied. One promising path to tackle these challenges is using photonic technologies, which are well-known for their connectivity capabilities, and have revolutionized communication systems. However, since combining them with non-optical quantum platforms continues to prove ve1y challenging, an extremely promising direction is developing a path toward an all-optical quantum information processing platform. While semiconductor-based photonic systems have been extensively studied for this goal over the past few decades, we propose a research program to study and develop networks of optical parametric oscillators (OPOs) as an all-optical quantum information processing system by exploring the frontiers of nonlinear and ultrafast photonic technologies in dielectrics. Recently, we have demonstrated that a semi-classical Ising machine based on OPO networks has a very promising computational performance; implementing these networks in the quantum regime would enable realization of a broad range of large-scale quantum information processing architectures. The main objective of this project is to extend the boundaries of the non-classical resources offered by OPO networks by exploring the frontiers of nonlinear and ultrafast optics to get a step closer to realization of all-optical quantum systems, and open a path toward scalable quantum photonic engineering. The project aims to (i) realize and experimental platform for realization of entangled states in time-multiplexed OPO networks, (ii) develop a theoretical framework for modeling time-multiplexed OPO networks, and (iii) explore potential integrated photonic paths for implementation of OPO networks in the quantum regime.
