Aspheric lens design proposal for near-perfect mode-matching of a broadband quantum dot micropillar to a single-mode fibre
Yichen Zhang, David Dlaka, James McDougall +5
Quantum dots in micropillars are one of the most promising options for a bright, deterministic single photon source. While highly efficient devices (>95%) have been designed, there…
Design principles for >90% efficiency and >99% indistinguishability broadband quantum dot cavities
David Dlaka, Petros Androvitsaneas, Andrew Young +3
Quantum dots have the potential to be the brightest deterministic single photon source with plausible high end applications in quantum computing and cluster state generation. In th…
Coherent scattering from coupled two level systems
Thomas Nutz, Samuel T. Mister, Petros Androvitsaneas +5
We study the resonance fluorescence properties of an optically active spin 1/2 system, elucidating the effects of a magnetic field on the coherence of the scattered light. We deriv…
Quantum modulation of a coherent state wavepacket with a single electron spin
P. Androvitsaneas, A. B. Young, T. Nutz +9
The interaction of quantum objects lies at the heart of fundamental quantum physics and is key to a wide range of quantum information technologies. Photon-quantum-emitter interacti…
High extraction efficiency source of photon pairs based on a quantum dot embedded in a broadband micropillar cavity
Laia Ginés, Magdalena Moczała-Dusanowska, David Dlaka +9
The generation of photon pairs in single quantum dots is based on a process that is, in its nature, deterministic. However, an efficient extraction of these photon pairs from a hig…
Stabilisation of an optical transition energy via nuclear Zeno dynamics in quantum dot-cavity systems
Thomas Nutz, Petros Androvitsaneas, Andrew Young +2
We investigate the effect of nuclear spins on the phase shift and polarisation rotation of photons scattered off a quantum dot-cavity system. We show that as the phase shift depend…
Optimal simultaneous measurements of incompatible observables of a single photon
Adetunmise C. Dada, Will McCutcheon, Erika Andersson +6
Joint or simultaneous measurements of non-commuting quantum observables are possible at the cost of increased unsharpness or measurement uncertainty. Many different criteria exist…
Efficient deterministic giant photon phase shift from a single charged quantum dot
P. Androvitsaneas, A. B. Young, J. M. Lennon +8
Solid-state quantum emitters have long been recognised as the ideal platform to realize integrated quantum photonic technologies. We use a self-assembled negatively charged QD in a…
A charged quantum dot micropillar system for deterministic light matter interactions
Petros Androvitsaneas, Andrew B. Young, Chritian Schneider +8
Quantum dots (QDs) are semiconductor nanostructures in which a three dimensional potential trap produces an electronic quantum confinement, thus mimicking the behaviour of single a…
Polarization engineering in photonic crystal waveguides for spin-photon entanglers
Andrew B. Young, Arthur Thijssen, Daryl M. Beggs +5
By performing a full analysis of the projected local density of states (LDOS) in a photonic crystal waveguide, we show that phase plays a crucial role in the symmetry of the light-…
Conditional phase shift from a quantum dot in a pillar microcavity
A. B. Young, R. Oulton, C. Y. Hu +8
Large conditional phase shifts from coupled atom-cavity systems are a key requirement for building a spin photon interface. This in turn would allow the realisation of hybrid quant…
