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 cryptography founded on the laws of physics could revolutionize the way in which
communication information is protected. Significant progresses in long-distance quantum …

Materials with strong second-order (χ^(2)) optical nonlinearity, especially lithium niobate,
play a critical role in building optical parametric oscillators (OPOs). However, chip-scale …

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 recent launch of the Micius quantum-enabled satellite heralds a major step forward for
long-range quantum communication. Using single-photon discrete-variable quantum states …

Quantum key distribution provides secure keys with information-theoretic security ensured
by the principle of quantum mechanics. The continuous-variable version of quantum key …

We demonstrate experimentally the feasibility of continuous variable quantum key
distribution (CV-QKD) in dense-wavelength-division multiplexing networks (DWDM), where …

We develop the concept of genuine N-partite Einstein-Podolsky-Rosen (EPR) steering. This
nonlocality is the natural multipartite extension of the original EPR paradox. Useful …

We review recent results on the simulation of quantum channels, the reduction of adaptive
protocols (teleportation stretching), and the derivation of converse bounds for quantum and …
