Fully passive entanglement based quantum key distribution scheme
Bo Liu, Matej Pivoluska, Johannes Handsteiner +5
In general, generation of entangled photon pairs and also the random choice of measurement basis can be implemented with passive optical devices in entanglement based quantum key d…
Quantum transport of high-dimensional spatial information with a nonlinear detector
Bereneice Sephton, Adam Vallés, Isaac Nape +6
Information exchange between two distant parties, where information is shared without physically transporting it, is a crucial resource in future quantum networks. Doing so with hi…
Clock synchronization with correlated photons
Christopher Spiess, Sebastian Töpfer, Sakshi Sharma +6
Event synchronisation is a ubiquitous task, with applications ranging from 5G technology to industrial automation and smart power grids. The emergence of quantum communication netw…
Quantum holography with undetected light
Sebastian Töpfer, Marta Gilaberte Basset, Jorge Fuenzalida +3
Holography exploits the interference of light fields to obtain a systematic reconstruction of the light fields wavefronts. Classical holography techniques have been very successful…
A quantum-enhanced wide-field phase imager
Robin Camphausen, Álvaro Cuevas, Luc Duempelmann +7
Quantum techniques can be used to enhance the signal-to-noise ratio in optical imaging. Leveraging the latest advances in single photon avalanche diode array cameras and multi-phot…
