Establishing an information-theoretic secret key between two parties using a quantum key
distribution (QKD) system is only possible when an accurate characterization of the quantum …

As quantum key distribution becomes a mature technology, it appears clearly that some
assumptions made in the security proofs cannot be justified in practical implementations …

The security of quantum key distribution (QKD) is severely threatened by discrepancies
between realistic devices and theoretical assumptions. Recently, a significant framework …

Characterizing the physical channel and calibrating the cryptosystem hardware are
prerequisites for establishing a quantum channel for quantum key distribution (QKD) …

The security of quantum key distribution (QKD) can easily be obscured if the eavesdropper
can utilize technical imperfections in the actual implementation. Here, we describe and …

We propose an efficient strategy to attack a continuous-variable (CV) quantum key
distribution (QKD) system, which we call homodyne detector blinding. This attack strategy …

We introduce a new continuous-variable quantum key distribution (CV-QKD) protocol, self-
referenced CV-QKD, that eliminates the need for transmission of a high-power local …

We identify and study a security loophole in continuous-variable quantum key distribution
(CVQKD) implementations, related to the imperfect linearity of the homodyne detector. By …

Quantum key distribution (QKD) utilizes the laws of quantum mechanics to achieve
information-theoretically secure key generation. This field is now approaching the stage of …

Quantum key distribution (QKD) is the first quantum information task to reach the level of
mature technology, already fit for commercialization. It aims at the creation of a secret key …
