Scalable quantum technologies require efficient conversion between qubits stored in solid-state systems and flying photonic qubits. Here, the authors demonstrate that the electromagnetic field chirality of a photonic waveguide leads to unidirectional

On-chip single-photon sources are key components for integrated photonic quantum technologies. Semiconductor quantum dots can exhibit near-ideal single-photon emission, but this can be significantly degraded in on-chip geometries owing to nearby etch

Using a novel two-pulse resonance fluorescence technique we demonstrate a Purcell factor of ∼35 in a cavity quantum dot system. Highly coherent single photons are efficiently emitted into a waveguide, forming a near-ideal source for integrated quan

We demonstrate a scheme for in-plane initialization and readout of a single exciton spin in an InGaAs quantum dot (QD) coupled to a GaAs nanobeam waveguide. The chiral coupling of the QD and the optical mode of the nanobeam enables spin initializatio

Scalable quantum technologies may be achieved by faithful conversion between matter qubits and photonic qubits in integrated circuit geometries. Within this context, quantum dots possess well-defined spin states (matter qubits), which couple efficien

Electrical control of on-chip routing of photons emitted by a single InAs/GaAs self-assembled quantum dot (SAQD) is demonstrated in a photonic crystal cavity-waveguide system. The SAQD is located inside an H1 cavity, which is coupled to two photonic

GaAs provides a versatile platform for developing on-chip integrated quantum-optical circuits. In this paper we review progress in developing spin-photon interfaces, on-chip beam-splitters and coherent single photon sources based on GaAs photonics.

We demonstrate the monolithic integration of an on-demand quantum emitter in the form of a single self-assembled InGaAs quantum dot with an air clad, free standing directional coupler acting as a beam-splitter for anti-bunched light.
We present a waveguide-coupled photonic crystal H1 cavity\ud structure in which the orthogonal dipole modes couple to spatially separated\ud photonic crystal waveguides. Coupling of each cavity mode to its respective\ud waveguide with equal efficien

We demonstrate coherent control of a quantum dot exciton using photocurrent detection with a sinusoidal reverse bias. Optical control is performed at low bias, where tunneling-limited coherence times are long. Following this step, the tunneling rates
