Efficient optimisation of multi-parameter quantum control protocols for strongly-coupled systems
Sion Meredith, Oliver Dudgeon, Wojciech Bukalski +4
Achieving high-fidelity control in the presence of strong non-Markovian noise is critical for the optimization of emergent solid-state quantum devices. We present a highly efficien…
Four-Photon Interference with a High-Efficiency Quantum Dot Source
Alistair J. Brash, Luke Brunswick, Mark R. Hogg +6
While two-photon Hong-Ou-Mandel interference visibility has become a standard metric for single-photon sources, many optical quantum technologies require the generation and manipul…

N. J. Martin, A. J. Brash, A. Tomlinson +12
Telecom wavelength quantum dots (QDs) are emerging as a promising solution for generating deterministic single photons compatible with existing fiber optic infrastructure. Emission…
Purcell-Enhanced Single Photons at Telecom Wavelengths from a Quantum Dot in a Photonic Crystal Cavity
Catherine L. Phillips, Alistair J. Brash, Max Godsland +10
Quantum dots are promising candidates for telecom single photon sources due to their tunable emission across the different low-loss telecommunications bands, making them compatible…
Nanocavity enhanced photon coherence of solid-state quantum emitters operating up to 30 K
Alistair J. Brash, Jake Iles-Smith
Solid-state emitters such as epitaxial quantum dots have emerged as a leading platform for efficient, on-demand sources of indistinguishable photons, a key resource for many optica…
Cavity-enhanced excitation of a quantum dot in the picosecond regime
Alisa Javadi, Natasha Tomm, Nadia O. Antoniadis +6
A major challenge in generating single photons with a single emitter is to excite the emitter while avoiding laser leakage into the collection path. Ideally, any scheme to suppress…
