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…
On-Demand Single Photons with High Extraction Efficiency and Near-Unity Indistinguishability from a Resonantly Driven Quantum Dot in a Micropillar
Xing Ding, Yu He, Z. -C. Duan +9
Scalable photonic quantum technologies require on-demand single-photon sources with simultaneously high levels of purity, indistinguishability, and efficiency. These key features,…
Highly indistinguishable on-demand resonance fluorescence photons from a deterministic quantum dot micropillar device with 75 extraction efficiency
Sebastian Unsleber, Yu-Ming He, Sebastian Maier +6
The implementation and engineering of bright and coherent solid state quantum light sources is key for the realization of both on chip and remote quantum networks. Despite tremendo…
Observation of resonance fluorescence and the Mollow-triplet from a coherently driven site-controlled quantum dot
Sebastian Unsleber, Sebastian Maier, Dara P. S. McCutcheon +8
Resonant excitation of solid state quantum emitters has the potential to deterministically excite a localized exciton while ensuring a maximally coherent emission. In this work, we…
Deterministic generation of bright single resonance fluorescence photons from a Purcell-enhanced quantum dot-micropillar system
Sebastian Unsleber, Christian Schneider, Sebastian Maier +6
We report on the observation of bright emission of single photons under pulsed resonance fluorescence conditions from a single quantum dot (QD) in a micropillar cavity. The brightn…
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…
Downconversion quantum interface for a single quantum dot spin and 1550-nm single-photon channel
Jason S. Pelc, Leo Yu, Kristiaan De Greve +11
Long-distance quantum communication networks require appropriate interfaces between matter qubit-based nodes and low-loss photonic quantum channels. We implement a downconversion q…
