A Controlled-NOT (CNOT) Gate Based on Quantum Interference in Cascaded Silicon Dual-ring Resonators

Not Accessible

Your library or personal account may give you access

Abstract

We propose a controlled-NOT (CNOT) gate based on two-photon quantum interference in cascaded silicon dual-ring resonators with Mach-Zehnder interferometer-assisted coupling. We illustrate the working principle and the design parameters of the device by theoretical modeling.
