The biexciton binding energy is exploited to create an extremely clean single photon source via two-photon resonant excitation of an InAs/GaAs quantum dot and full coherent control of the ground-biexciton state qubit is performed and an extended coherence time is observed.

A new scheme based on quantum dot-bimodal cavity coupling system to realize all-optical switch and logic gates in low-photon-number regime and the AND/OR logic gates based on photon polarization work well in ultra-low energy magnitude.

Indistinguishable photons from a single-photon device

Observations unequivocally show that quantum information tasks are achievable in solid-state cavity QED by observing quantum correlations in photoluminescence from a photonic crystal nanocavity interacting with one, and only one, quantum dot located precisely at the cavity electric field maximum.

Loss-enabled sub-poissonian light generation in a bimodal nanocavity.

- PhysicsPhysical review letters
- 2012

It is shown that the effect results from an interference between the coherent light transmitted through the resonant cavity and the super-poissonian light generated by photon-induced tunneling, and this effect vanishes in the absence of the cavity loss.
