Aptamers are a promising class of affinity reagents because signal transduction mechanisms can be built into the reagent, so that they can directly produce a physically measurable output signal upon target binding. However, endowing the signal transduction functionality into an aptamer remains a trial‐and‐error process that can compromise its affinity or specificity and typically requires knowledge...
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.
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.
We demonstrate the fabrication and optical characterization of diamond nanopillar arrays containing silicon-vacancy (SiV−) color centers. Micro-photoluminescence reveals narrow linewidths and small inhomogeneous broadening of SiV− emission from the nanopillars.
