Two-photon lasing by a single quantum dot in a high- Q microcavity
We investigate theoretically two-photon processes in a microcavity containing one quantum dot in the strong-coupling regime. The cavity mode can be tuned to resonantly drive the two-photon transition…
Spontaneous two-photon emission from a single quantum dot.
TLDR
This work investigated photoluminescence from the neutral biexciton in a single semiconductor quantum dot coupled with a high Q photonic crystal nanocavity and observed spontaneous two-photon emission from a solid-state single quantum emitter.
Deterministic photon pairs and coherent optical control of a single quantum dot.
TLDR
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.
Low-photon-number optical switch and AND/OR logic gates based on quantum dot-bimodal cavity coupling system
TLDR
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
TLDR
It is found that consecutive photons are largely indistinguishable, with a mean wave-packet overlap as large as 0.81, making this source useful in a variety of experiments in quantum optics and quantum information.
Unconventional photon blockade in a photonic molecule containing a quantum dot
Generation of a two-photon state from a quantum dot in a microcavity
We propose and characterize a two-photon (2P) source that emits in a highly polarized, monochromatic and directional beam, realized by means of a quantum dot embedded in a linearly polarized cavity.…
Spin-resolved Purcell effect in a quantum dot microcavity system.
TLDR
The spin selective coupling of the exciton state with cavity mode in a single quantum dot (QD)-micropillar cavity system is demonstrated, paving the way for the realization of future quantum light sources and the quantum information processing applications.
Quantum nature of a strongly coupled single quantum dot–cavity system
TLDR
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.
TLDR
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.
