Quantum photonics

Photonic devices have been the dominant workhorse of data communication in the internet age. Rapid improvements in efficiency and sophistication are now extending these devices into the quantum regime, where single photons mediate interactions between embedded on-chip memories coupled to complex photonic circuits.  We are studying methos to use integrated photonics to build large and complex quantum systems composed of photons and spins contained in a semiconductor chip.  These devices could implement quantum algorithms and simulate large and complex systems of strongly interacting photons.
