The recent advances in quantum information processing, sensing, and communications are
surveyed with the objective of identifying the associated knowledge gaps and formulating a …

Here we present a new protocol for controlled quantum key agreement and another protocol
for key agreement with a specific focus on the security analysis. Specifically, detailed …

Abstract Quantum Key Distribution allows two parties to establish a secret key that is secure
against computationally unbounded adversaries. To extend the distance between parties …

Quantum conference key agreement (QCKA) enables the unconditional secure distribution
of conference keys among multiple participants. Due to challenges in high-fidelity …

Secret key exchange relies on the creation of correlated signals, serving as the raw resource
for secure communication. Thermal states exhibit Hanbury Brown and Twiss correlations …

The wavelength attack utilizes the dependence of beam splitters (BSs) on wavelength to
cause legitimate users Alice and Bob to underestimate their excess noise so that Eve can …

Quantum key distribution (QKD) allows the generation of cryptographic keys beyond the
computational hardness paradigm and is befitting for secure data transmission requiring …

Quantum Key Distribution allows two parties to establish a secret key that is secure against
computationally unbounded adversaries. To extend the distance between parties, quantum …
