DOI: 10.1038/s41534-019-0180-9
Abstract: In theory, quantum key distribution (QKD) allows secure communications between two parties based on physical laws. However, most of the security proofs of QKD today make unrealistic assumptions and neglect many relevant device imperfections. As… read more here.

DOI: 10.1038/s41598-021-87574-4
Abstract: Inspired by the methodology used for classical cryptographic hardware, we consider the use of attack ratings in the context of QKD security evaluation. To illustrate the relevance of this approach, we conduct an experimental vulnerability… read more here.

DOI: 10.1063/1.5036827
Abstract: Secure communication networks enabled by commercial quantum key distribution (QKD) are already available. However, their widespread deployment will require great efforts towards reducing the currently prohibitive cost of QKD systems. Here, we propose a compact… read more here.

DOI: 10.1088/1367-2630/aad839
Abstract: Security proofs of quantum key distribution (QKD) typically assume that the devices of the legitimate users are perfectly shielded from the eavesdropper. This assumption is, however, very hard to meet in practice, and thus the… read more here.

DOI: 10.1103/physrevapplied.14.064031
Abstract: In this work, we explore the feasibility of performing satellite-to-Earth quantum key distribution (QKD) using the orbital angular momentum (OAM) of light. Due to the fragility of OAM states the conventional wisdom is that turbulence… read more here.

DOI: 10.1103/physrevlett.130.220801
Abstract: Passive implementations of quantum key distribution (QKD) sources are highly desirable as they eliminate side-channels that active modulators might introduce. Up till now, passive decoy-state and passive encoding BB84 schemes have both been proposed. Nonetheless,… read more here.

DOI: 10.1109/access.2020.3009090
Abstract: As is known, quantum key distribution (QKD) can provide information-theoretic security under some preconditions, one of which is that the identity of each participant has been authenticated. And quantum identity authentication (QIA) can achieve this… read more here.

DOI: 10.1109/access.2022.3196677
Abstract: 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. This is the case of QKD systems using a… read more here.
