Towards an All-Silicon DV-QKD Transmitter Sourced by a Ge-on-Si Light Emitter
Florian Honz, Nemanja Vokić, Philip Walther +2
We investigate the behavior of a Ge-on-Si light source and demonstrate its feasibility for polarization-encoded discrete-variable quantum key distribution following the BB84 protoc…
Harnessing high-dimensional temporal entanglement using limited interferometric setups
Alexandra Bergmayr, Florian Kanitschar, Matej Pivoluska +1
High-dimensional entanglement has shown to have significant advantages in quantum communication. It is available in many degrees of freedom and in particular in the time-domain rou…
Distribution of Telecom Entangled Photons through a 7.7 km Antiresonant Hollow-Core Fiber
Michael Antesberger, Carla M. D. Richter, Francesco Poletti +6
State of the art classical and quantum communication rely on standard optical fibers with solid cores to transmit light over long distances. However, recent advances have led to th…
Polarization-Encoded BB84 QKD Transmitter Sourced by a SiGe Light Emitter
Florian Honz, Nemanja Vokic, Philip Walther +2
We demonstrate a polarization-encoded BB84 transmitter sourced by a SiGe light source and show that such a potentially "all-silicon" QKD scheme can operate well below the QBER thre…
Demonstration of quantum-digital payments
Peter Schiansky, Julia Kalb, Esther Sztatecsny +5
Digital payments have replaced physical banknotes in many aspects of our daily lives. Similarly to banknotes, they should be easy to use, unique, tamper-resistant and untraceable,…
