Quantum cryptography exploits principles of quantum physics for the secure processing of
information. A prominent example is secure communication, ie, the task of transmitting …

Quantum key distribution—the establishment of information-theoretically secure keys based
on quantum physics—is mainly limited by its practical performance, which is characterised …

Twin-field (TF) quantum key distribution (QKD) fundamentally alters the rate-distance
relationship of QKD, offering the scaling of a single-node quantum repeater. Although recent …

Photonic quantum technologies represent a promising platform for several applications,

The security of quantum key distribution (QKD) usually relies on that the users' devices are
well characterized according to the security models made in the security proofs. In contrast …

All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

Quantum key distribution (QKD) is the first quantum information task to reach the level of
mature technology, already fit for commercialization. It aims at the creation of a secret key …

Quantum Information Theory is an area of physics which studies both fundamental and
