Time-bin encoded quantum key distribution over 120 km with a telecom quantum dot source
Jipeng Wang, Joscha Hanel, Zenghui Jiang +11
Quantum key distribution (QKD) with deterministic single photon sources has been demonstrated over intercity fiber and free-space channels. The previous implementations relied main…

Low-Noise Cascaded Frequency Conversion of nm Light to the Telecommunication C-Band in a Single-Waveguide Device
Fabrice von Chamier, Joscha Hanel, Chris Müller +3
Interconnected quantum devices are the building blocks of quantum networks, where state transduction plays a central role. The frequency conversion of photons into the telecommunic…
