Quantum Noise in Photonic Logic: from Free Carriers to Ising Machines
As nanophotonics and materials research drive optical logic to the low-power, few-photon
limit, quantum properties of light start to matter. Even if we aren’t building a quantum
computer, these quantum effects can play a key role limiting the performance of existing
devices, or enabling entirely new dynamics. I present quantum simulations of devices
based on semiconductor (free-carrier) optical nonlinearities and propose an optical
annealing machine based on this effect. In addition, I apply these methods to study
synchronously-pumped optical parametric oscillator (OPO) networks, which have recently
been proposed and demonstrated, and are a promising alternative to digital computers for
Ising optimization problems.
