A deterministic and efficient source of frequency-polarization hyper-encoded photonic qubits
N. Coste, D. A. Fioretto, S. E. Thomas +12
The frequency or color of photons is an attractive degree of freedom to encode and distribute the quantum information over long distances. However, the generation of frequency-enco…
Modelling Markovian light-matter interactions for quantum optical devices in the solid state
Stephen C. Wein
The desire to understand the interaction between light and matter has stimulated centuries of research, leading to technological achievements that have shaped our world. One contem…
Quantum repeaters based on individual electron spins and nuclear-spin-ensemble memories in quantum dots
Kenneth Sharman, Faezeh Kimiaee Asadi, Stephen C Wein +1
Inspired by recent developments in the control and manipulation of quantum dot nuclear spins, which allow for the transfer of an electron spin state to the surrounding nuclear-spin…
Hong-Ou-Mandel Interference with Imperfect Single Photon Sources
H. Ollivier, S. E. Thomas, S. C. Wein +12
Hong-Ou-Mandel interference is a cornerstone of optical quantum technologies. We explore both theoretically and experimentally how the nature of unwanted multi-photon components of…
Analyzing photon-count heralded entanglement generation between solid-state spin qubits by decomposing the master equation dynamics
Stephen C. Wein, Jia-Wei Ji, Yu-Feng Wu +3
We analyze and compare three different schemes that can be used to generate entanglement between spin qubits in optically-active single solid-state quantum systems. Each scheme is…
Protocols for long-distance quantum communication with single Er ions
F. Kimiaee Asadi, S. C. Wein, C. Simon
We design a quantum repeater architecture using individual Er ions doped into YSiO crystal. This ion is a promising candidate for a repeater protocol because of its…
