Nanocrystals in silicon photonic crystal standing-wave cavities as spin-photon phase gates for quantum information processing

Y.-F. Xiao, J. Gao, X. Yang +3 more

By virtue of a silicon high-Q photonic crystal nanocavity, we propose and examine theoretically interactions between a stationary electron spin qubit of a semiconductor nanocrystal and a flying photon qubit. 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.

Quantum Information Interface on a Photonic Crystal Chip

Paul Mertin, Bernd Witzigmann

Quantum systems for information processing rely on the distribution of quantum information in a network. Lanthanide complexes coupled to an optical cavity can act as an interface between a stationary and a flying QuBit. Here we show that in such a system the stationary quantum information can be mapped onto a photon, paving the way for a node in photonic quantum network.

A hybrid quantum photonic interface for solid state qubits

Dirk Englund, Luozhou Li, J. S. Hodges +6 more

Optical nanocavities enable a strong interaction between single photons and single emitters. An appealing application is the construction of a quantum interface for photonic and solid state qubits. Since the material of the solid state qubit is often dierent from the nanocavity, there has been considerable interest in combining the two in a hybrid architecture. We describe our recent development of such a hybrid interface based a Gallium Phosphide photonic crystal nanocavity that is scanned and deterministically coupled to single emitters on a surface. The technique is used to couple the cavity to the nitrogen vacancy center in diamond, an emitter system with optically accessible electron spins and the ability to transfer electronic spin states to nuclear spins.

Single photon nonlinear optics on photonic crystal chips

Dirk Englund

A single semiconductor quantum dot that is strongly coupled to a photonic crystal nanocavity yields optical nonlinearities at the single photon level. The promise of quantum information processing is driving developments in several different physical implementations. Photons are attractive as carriers of quantum information be-cause they can travel long distances without losing their infor-mation through interactions with their environment. However, their passive nature can be a problem in applications such as the construction of logic gates, where it is necessary for two or more photons to interact. This interaction requires a nonlinear optical medium. Particularly strong nonlinearities are achieved when photons drive an emitter near its resonance frequency, and this nonlinearity is even greater if the photon is confined near the emitter in an optical cavity.
