Finite-range multiplexing enhances quantum key distribution via quantum repeaters
Silvestre Abruzzo, Hermann Kampermann, Dagmar Bruß
Quantum repeaters represent one possible way to achieve long-distance quantum key distribution. Collins et al. in [Phys. Rev. Lett. 98, 060502 (2007)] proposed multiplexing as meth…
Measurement-device-independent quantum key distribution with quantum memories
Silvestre Abruzzo, Hermann Kampermann, Dagmar Bruß
We generalize measurement-device-independent quantum key distribution [ H.-K. Lo, M. Curty, and B. Qi, Phys. Rev. Lett. 108, 130503 (2012) ] to the scenario where the Bell-state me…
Quantum repeaters and quantum key distribution: the impact of entanglement distillation on the secret key rate
Sylvia Bratzik, Silvestre Abruzzo, Hermann Kampermann +1
We investigate quantum repeaters in the context of quantum key distribution. We optimize the secret key rate per memory per second with respect to different distillation protocols…
Quantum repeaters and quantum key distribution: analysis of secret key rates
Silvestre Abruzzo, Sylvia Bratzik, Nadja K. Bernardes +3
We analyze various prominent quantum repeater protocols in the context of long-distance quantum key distribution. These protocols are the original quantum repeater proposal by Brie…
Finite-key analysis of the six-state protocol with photon-number-resolution detectors
Silvestre Abruzzo, Markus Mertz, Hermann Kampermann +1
The six-state protocol is a discrete-variable protocol for quantum key distribution, that permits to tolerate a noisier channel than the BB84 protocol. In this work we provide a lo…
QKD with finite resources: secret key rates via Rényi entropies
Silvestre Abruzzo, Hermann Kampermann, Markus Mertz +1
A realistic Quantum Key Distribution (QKD) protocol necessarily deals with finite resources, such as the number of signals exchanged by the two parties. We derive a bound on the se…
