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…
Asymmetric two-photon response of an incoherently driven quantum emitter
Lennart Jehle, Lena M. Hansen, Patrik I. Sund +7
Quantum emitters promise to emit exactly one photon with high probability when pumped by a laser pulse. However, even in ideal systems, re-excitation during a laser pulse causes th…
Efficient fiber coupling of telecom single-photons from circular Bragg gratings
Nam Tran, Pavel Ruchka, Sara Jakovljevic +9
Deterministic sources of quantum light are becoming increasingly relevant in the development of quantum communication, particularly in deployed fiber networks. Therefore, efficient…
Initialization of Neutral and Charged Exciton Spin States in a Telecom-Emitting Quantum Dot
Giora Peniakov, Johannes Michl, Mohamed Helal +6
Photonic cluster states are highly entangled states that allow for photonic quantum computing and memory-less quantum repeaters. Their generation has been recently demonstrated usi…
Telecom wavelength quantum dots interfaced with silicon-nitride circuits via photonic wire bonding
Ulrich Pfister, Daniel Wendland, Florian Hornung +10
Photonic integrated circuits find ubiquitous use in various technologies, from communication, to computing and sensing, and therefore play a crucial role in the quantum technology…
