Nanocrystals in Silicon Photonic Crystal Standing-Wave Cavities as Spin-Photon Phase Gates for Quantum Information Processing
Qphotonic crystal nanocavity, we propose and examine theoretically interactions between a stationary electron spin qubit of a semiconductornanocrystal and a flying photonqubit. Firstly, we introduce, derive, and demonstrate the explicit conditions toward realization of a spin-photon phase gate, and propose these interactions as a generalized quantum interface for quantum information processing. Secondly, we examine single-spin-induced reflections as direct evidence of intrinsic bare and dressed modes in our coupled nanocrystal-cavity system.
