Quantum Flows for Secret Key Distribution in the Presence of the Photon Number Splitting Attack
Entropy, 2014 Physical implementations of quantum key distribution (QKD) protocols, like the Bennett-Brassard (BB84), are forced to use attenuated coherent quantum states, because the sources of single photon states are not functional yet for QKD applications. However,

Applying Gaussian quantum discord to quantum key distribution
, 2014 In this paper, we theoretically prove that the Gaussian quantum discord state of optical field can be used to complete continuous variable (CV) quantum key distribution (QKD). The calculation shows that secret key can be distilled with a Gaussian quantum

Resilient Quantum Key Distribution (QKD)-Integrated Optical Networks With Secret-Key Recovery Strategy [PDF]
IEEE Access, 2019 Quantum key distribution (QKD) promises to deliver secure keys, which can be applied for security demands in optical networks by using cost-efficient and scalable lightpaths. To achieve such secure communication, the QKD integrated with optical networks has become a promising scenario to provide key provisioning services in optical networks.

Satellite Quantum Communications When Man-in-the-Middle Attacks Are Excluded
Entropy, 2019 An application of quantum communications is the transmission of qubits to create shared symmetric encryption keys in a process called quantum key distribution (QKD). Contrary to public-private key encryption, symmetric encryption is considered safe from (

Practical Side-Channel Attack on Free-Space QKD Systems With Misaligned Sources and Countermeasures
IEEE Access, 2022 Practical implementations of quantum key distribution (QKD) protocols can introduce additional degrees of freedom in the quantum states that may render them distinguishable to an eavesdropper.

A New Security Proof for Twin-Field Quantum Key Distribution (QKD)
Applied Sciences, 2023 Twin-field QKD (TF-QKD) protocols allow for increased key rates over long distances when compared to standard QKD protocols. They are even able to surpass the PLOB bound without the need for quantum repeaters. In this work, we revisit a previous TF-QKD protocol and derive a new, simple, proof of security for it.

Metropolitan quantum key distribution with silicon photonics
, 2017 Photonic integrated circuits (PICs) provide a compact and stable platform for quantum photonics. Here we demonstrate a silicon photonics quantum key distribution (QKD) transmitter in the first high-speed polarization-based QKD field tests.
