Frequency Domain Quantum Photonics

Abstract
Quantum frequency conversion is the process by which the wavelength of a light field is converted to another wavelength while still fully maintaining its quantum state. I will describe our recent research that utilizes the nonlinear optical process of four-wave mixing to perform ultralow noise quantum frequency conversion with efficiencies approaching 100%. We also show how this nonlinear process can be used to realize other novel quantum phenomena in the frequency domain including Hong-Ou-Mandel interference, quantum communication, and an N-way beamsplitter.
