Quantum key distribution (QKD) constitutes a symmetric secret key negotiation protocol
capable of maintaining information-theoretic security. Given the recent advances in QKD …

In principle, quantum key distribution (QKD) offers information-theoretic security based on
the laws of physics. In practice, however, the imperfections of realistic devices might …

Quantum key distribution has emerged as the most viable scheme to guarantee information
security in the presence of large-scale quantum computers and, thanks to the continuous …

Single-photon detectors based on superconducting nanowires (SSPDs or SNSPDs) have
rapidly emerged as a highly promising photon-counting technology for infrared wavelengths …

Quantum key distribution (QKD) offers the promise of absolutely secure communications.
However, proofs of absolute security often assume perfect implementation from theory to …

Secret communication over public channels is one of the central pillars of a modern
information society. Using quantum key distribution this is achieved without relying on the …

The problem of implementation security in quantum key distribution (QKD) refers to the
difficulty of meeting the requirements of mathematical security proofs in real‐life QKD …

Quantum key distribution (QKD) based on the laws of quantum physics allows the secure
distribution of secret keys over an insecure channel. Unfortunately, imperfect …

In this paper, we study the unconditional security of the so-called measurement-device-
independent quantum key distribution (MDIQKD) with the basis-dependent flaw in the …

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 …
