High Purcell factor generation of coherent on-chip single photons
F. Liu, A. J. Brash, J. O'Hara +11
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…
Path-dependent initialization of a single quantum dot exciton spin in a nano-photonic waveguide
Rikki J. Coles, David M. Price, Ben Royall +4
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…
Chirality of nanophotonic waveguide with embedded quantum emitter for unidirectional spin transfer
R. J. Coles, D. M. Price, J. E. Dixon +6
Scalable quantum technologies require faithful conversion between matter qubits storing the quantum information and photonic qubits carrying the information in integrated circuits…
On-chip resonantly-driven quantum emitter with enhanced coherence
M. N. Makhonin, J. E. Dixon, R. J. Coles +4
Advances in nanotechnology provide techniques for the realisation of integrated quantum-optical circuits for on-chip quantum information processing(QIP). The indistinguishable sing…
Monolithic Integration of a Quantum Emitter with a Compact On-chip Beam-splitter
N. Prtljaga, R. J. Coles, J. OHara +4
A fundamental component of an integrated quantum optical circuit is an on-chip beam-splitter operating at the single-photon level. Here we demonstrate the monolithic integration of…
Waveguide-Coupled Photonic Crystal Cavity for Quantum Dot Spin Readout
R. J. Coles, N. Prtljaga, B. Royall +3
We present a waveguide-coupled photonic crystal H1 cavity structure in which the orthogonal dipole modes couple to spatially separated photonic crystal waveguides. Coupling of each…
Enhanced photocurrent readout for a quantum dot qubit by bias modulation
J. H. Quilter, R. J. Coles, A. J. Ramsay +2
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-limi…
