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 …

Autonomous “Things” is becoming the future trend as the role, and responsibility of IoT keep
diversifying. Its applicability and deployment need to re-stand technological advancement …

With the rise of quantum technologies, data security increasingly relies on quantum
cryptography and its most notable application, quantum key distribution (QKD). Yet, current …

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 …

We present a scheme of quantum repeater that uses entangled multimode coherent states
