This article describes the current technical level of developments in the field of continuous-
variable quantum key distribution (CV-QKD). Various classifications are described, the …

Many quantum key distribution systems employ a laser followed by an optical attenuator to
prepare weak coherent states in the source. Their mean photon number must be …

Vulnerabilities of components used in quantum-key-distribution systems affect its
implementation security and must be taken into consideration during system development …

We experimentally demonstrate that a single-photon detector ID210 commercially available
from ID Quantique is vulnerable to blinding and can be fully controlled by bright illumination …

Although quantum communication systems are being deployed on a global scale, their
realistic security certification is not yet available. Here we present a security evaluation and …

In this paper we report a continuous-variable quantum key distribution protocol using
multimode coherent states generated on subcarrier frequencies of the optical spectrum. We …

Non-Gaussian quantum states are crucial to fault-tolerant quantum computation with
continuous-variable systems. Usually, generation of such states involves trade-offs between …

In this paper we propose feasibility demonstration of twin-field quantum key ditribution
system based on multi-mode weak coherent phase-coded states. Their utilization provides …

In this paper, we consider the influence of device imperfections on the performance of the
subcarrier wave quantum key distribution system. For instance, we consider the utilization of …

In this paper we present the approach for description of quantum control attack based on
combined protocol and hardware loopholes. It consolidates intercept-resend attack and …
