The progress in integration of nanodiamond with photonic devices is analyzed in the light of quantum optical applications. Nanodiamonds host a variety of optically active defects, called color centers, which provide rich ground for photonic engineering. Theoretical introduction describing light and matter interaction between optical modes and a quantum emitter is presented, including the role of the...
We fabricate arrays of diamond nanopillars containing single SiV− centers with high yield and spectral stability, and perform ultrafast, all-optical complete coherent control over the state of individual SiV− centers on picosecond timescales. We demonstrate Rabi oscillation, Ramsey interference, and full SU(2) control over the qubit state.
We investigate the effects of homodyne interference on light transmitted through a dissipative Jaynes-Cummings system and use quantum optical simulations to show how interference can dramatically improve the generation of high-quality single photons.
We demonstrate the generation of single- and two-photons at a time from a quantum dot-photonic crystal resonator system. Controlling the detuning between emitter and cavity allows us to drive a nonlinear ladder of hybridized light-matter states.
On-demand single-photon sources that produce a single photon as a response to a deterministic input are widely regarded as critical light sources for quantum key distribution, quantum repeaters, and quantum information science generally [1]. The wavepackets from such a source must have low probability to contain more than one photon, exist in a pure state so they may interfere with one another, and...
We investigated an ultrafast phonon-assisted population transfer between polaritons from a strongly coupled quantum dot-photonic crystal cavity system. In particular, we demonstrated complete coherent control and single-photon generation from a polariton.
Indistinguishable photon emission was investigated from a quantum dot-photonic crystal resonator system for the first time. This solid-state cavity quantum electrodynamical platform produced robust and high-fidelity generation of indistinguishable photons at unprecedented rates.
Progress in cavity quantum electrodynamics (cQED) trends to decreasing mode volume and increasing light-matter interaction. We demonstrate a metal-semiconductor nanopillar cQED system that exhibits bright single-photon generation, strong Purcell enhancement, and viability as a new platform for cQED.
