Symmetric autocompensating quantum key distribution [PDF]
, 2004 We present quantum key distribution schemes which are autocompensating (require no alignment) and symmetric (Alice and Bob receive photons from a central source) for both polarization and time-bin qubits.

Quantum Key Distribution Networks: Challenges and Future Research Issues in Security
Applied Sciences, 2021 A quantum key distribution (QKD) network is proposed to allow QKD protocols to be the infrastructure of the Internet for distributing unconditional security keys instead of existing public-key cryptography based on computationally complex mathematical ...

Cost-Optimization-Based Quantum Key Distribution over Quantum Key Pool Optical Networks
Entropy, 2023 The Measurement-Device-Independent-Quantum Key Distribution (MDI-QKD) has the advantage of extending the secure transmission distances. The MDI-QKD combined with the Hybrid-Trusted and Untrusted Relay (HTUR) is used to deploy large-scale QKD networks ...

No Signaling and Quantum Key Distribution [PDF]
Physical Review Letters, 2005 Standard quantum key distribution protocols are provably secure against eavesdropping attacks, if quantum theory is correct. It is theoretically interesting to know if we need to assume the validity of quantum theory to prove the security of quantum key distribution, or whether its security can be based on other physical principles.

Quantum dense key distribution [PDF]
Physical Review A, 2004 This paper proposes a new protocol for quantum dense key distribution. This protocol embeds the benefits of a quantum dense coding and a quantum key distribution and is able to generate shared secret keys four times more efficiently than BB84 one. We hereinafter prove the security of this scheme against individual eavesdropping attacks, and we present ...
