Secure Quantum Key Distribution over 421 km of Optical Fiber.
We present a quantum key distribution system with a 2.5 GHz repetition rate using a three-state time-bin protocol combined with a one-decoy approach. Taking advantage of superconducting single-photonExpand

Finite-key analysis for the 1-decoy state QKD protocol
TLDR
It has been shown that in the asymptotic case of infinite-key length, the 2-decoy state Quantum Key Distribution (QKD) protocol outperforms the 1- decoy state protocol. Expand

Simple and high-speed polarization-based QKD
We present a simplified BB84 protocol with only three quantum states and one decoy-state level. We implement this scheme using the polarization degree of freedom at telecom wavelength. Only oneExpand

Security proof for a simplified Bennett-Brassard 1984 quantum-key-distribution protocol
The security of quantum key distribution (QKD) has been proven for different protocols, in particular for the BB84 protocol. It has been shown that this scheme is robust against eventualExpand
