Photon Interactions

Single-photon switches and transistors generate strong photon-photon interactions that are essential for quantum circuits and networks. However, the deterministic control of an optical signal with a single photon requires strong interactions with a quantum memory, which has been challenging to achieve in a solid-state platform. We demonstrate a single-photon switch and transistor enabled by a solid-state quantum memory. Our device consists of a semiconductor spin qubit strongly coupled to a nanophotonic cavity. The spin qubit enables a single 63-picosecond gate photon to switch a signal field containing up to an average of 27.7 photons before the internal state of the device resets. Our results show that semiconductor nanophotonic devices can produce strong and controlled photon-photon interactions that could enable high-bandwidth photonic quantum information processing.

We demonstrate a linear optical protocol to generate W state in terms of optical elements within a network. The proposed setup involves simple linear optical elements, N-photon polarization entangled state, and conventional photon detectors that only distinguish the vacuum and nonvacuum Fock number states. We show that with local operations, single-photon measurement, and one way classical communication, the protocol can be successfully realized with a certain probability.
