Quantum key distribution (QKD) allows for unconditionally secure communication between two parties (Alice and Bob). A recent breakthrough in the theory of QKD is the treatment of finite-key… (More)

Quantum key distribution (QKD) allows for communication with security guaranteed by quantum theory. The main theoretical problem in QKD is to calculate the secret key rate for a given protocol.… (More)

Interferometers capture a basic mystery of quantum mechanics: a single particle can exhibit wave behaviour, yet that wave behaviour disappears when one tries to determine the particle's path inside… (More)

Background.— In practical quantum key distribution (QKD) devices, an attenuated laser source has been commonly used instead of a single-photon source. To counteract more powerful eavedropping attacks… (More)
Introduction.—Quantum key distribution (QKD) will play an important role in quantum-safe cryptography. The main theoretical problem in QKD is to calculate how much secret key can be distributed by a… (More)
Noisy intermediate-scale quantum (NISQ) computers have significant decoherence, limiting the depth of circuits that can be implemented on them. A strategy for NISQ algorithms is to reduce the circuit… (More)

An approach to the unconditional security of quantum key distribution protocols is presented, which is based on the uncertainty principle. The approach applies to every case that has been treated via… (More)
