Giant Rydberg excitons in CuO probed by photoluminescence excitation spectroscopy
Marijn A. M. Versteegh, Stephan Steinhauer, Josip Bajo +7
Rydberg excitons are, with their ultrastrong mutual interactions, giant optical nonlinearities, and very high sensitivity to external fields, promising for applications in quantum…
Proximitized Josephson junctions in highly-doped InAs nanowires robust to optical illumination
Lily Yang, Stephan Steinhauer, Elia Strambini +7
We have studied the effects of optical-frequency light on proximitized InAs/Al Josephson junctions based on highly n-doped InAs nanowires at varying incident photon flux and at thr…
Passively stable distribution of polarisation entanglement over 192 km of deployed optical fibre
Sören Wengerowsky, Siddarth Koduru Joshi, Fabian Steinlechner +14
Quantum key distribution (QKD) based on entangled photon pairs holds the potential for repeater-based quantum networks connecting clients over long distance. We demonstrate long-di…
CuO Microcrystals Grown on Silicon as Platform for Quantum-Degenerate Excitons and Rydberg States
Stephan Steinhauer, Marijn A. M. Versteegh, André Mysyrowicz +2
Cuprous oxide (CuO) is a semiconductor with large exciton binding energy and significant technological importance in applications such as photovoltaics and solar water splittin…
In-field entanglement distribution over a 96 km-long submarine optical fibre
Sören Wengerowsky, Siddarth Koduru Joshi, Fabian Steinlechner +13
Techniques for the distribution of quantum-secured cryptographic keys have reached a level of maturity allowing them to be implemented in all kinds of environments, away from any f…
Semiconductor devices for entangled photon pair generation: a review
Adeline Orieux, Marijn A. M. Versteegh, Klaus D. Jöns +1
Entanglement is one of the most fascinating properties of quantum mechanical systems; when two particles are entangled the measurement of the properties of one of the two allows to…
