Asymmetric Protocols for Scalable High-Rate Measurement-Device-Independent Quantum Key Distribution Networks [PDF]
, 2019 Measurement-device-independent quantum key distribution (MDI-QKD) can eliminate detector side channels and prevent all attacks on detectors. The future of MDI-QKD is a quantum network that provides service to many users over untrusted relay nodes.

Explicit asymptotic secret key rate of continuous-variable quantum key distribution with an arbitrary modulation [PDF]
Quantum, 2021 We establish an analytical lower bound on the asymptotic secret key rate of continuous-variable quantum key distribution with an arbitrary modulation of coherent states. Previously, such bounds were only available for protocols with a Gaussian modulation,

Tomography increases key rates of quantum-key-distribution protocols [PDF]
Physical Review A, 2008 We construct a practically implementable classical processing for the BB84 protocol and the six-state protocol that fully utilizes the accurate channel estimation method, which is also known as the quantum tomography. Our proposed processing yields at least as high key rate as the standard processing by Shor and Preskill.

Second-order coding rates for key distillation in quantum key distribution
CoRR, 2019 The security of quantum key distribution has traditionally been analyzed in either the asymptotic or non-asymptotic regimes. In this paper, we provide a bridge between these two regimes, by determining second-order coding rates for key distillation in quantum key distribution under collective attacks. Our main result is a formula that characterizes the

Long-distance quantum key distribution using concatenated entanglement swapping with practical resources [PDF]
, 2016 We present our approach for sharing photons and assessing resultant four-photon visibility between two distant parties using concatenated entanglement swapping. In addition we determine the corresponding key generation rate and the quantum bit-error rate.

Key rates for quantum key distribution protocols with asymmetric noise
Physical Review A, 2020 We consider the asymptotic key rates achieved in the simplest quantum key distribution protocols, namely the BB84 and the six-state protocols, when non-uniform noise is present in the system. We first observe that higher qubit error rates do not necessarily imply lower key rates. Secondly, we consider protocols with advantage distillation and show that
