Quantum cryptography is arguably the fastest growing area in quantum information science.
Novel theoretical protocols are designed on a regular basis, security proofs are constantly …

The ability to distribute secret keys between two parties with information-theoretic security,
that is regardless of the capacities of a malevolent eavesdropper, is one of the most …

Quantum communications promises reliable transmission of quantum information, efficient
distribution of entanglement and generation of completely secure keys. For all these tasks …

Quantum illumination is a quantum-optical sensing technique in which an entangled source
is exploited to improve the detection of a low-reflectivity object that is immersed in a bright …

Quantum cryptography achieves a formidable task—the remote distribution of secret keys by
exploiting the fundamental laws of physics. Quantum cryptography is now headed towards …

The continuous-variable version of quantum key distribution (QKD) offers the advantages
(over discrete-variable systems) of higher secret key rates in metropolitan areas, as well as …

Continuous-variable systems realized in quantum optics play a major role in quantum
information processing, and it is also one of the promising candidates for a scalable …

The recent launch of the Micius quantum-enabled satellite heralds a major step forward for
