In counterfactual quantum key distribution (CQKD) information is transferred, in a secure
way, between Alice and Bob even when no particle carrying the information is in fact …

Amplitude-dam** (AD) channels are good models for many physical scenarios, and so the
development of protocols to discriminate between them is an important task in quantum …

A proof-of-principle demonstration of a one-way polarization encoding quantum key
distribution (QKD) system is demonstrated. This approach can automatically compensate for …

Counterfactual quantum key distribution provides natural advantage against the
eavesdrop** on the actual signal particles. It can prevent the photon-number-splitting …

Basis deviation is the reference-frame deviation between a sender and receiver caused by
satellite motion in satellite-to-ground quantum communications. It increases the quantum-bit …

SARG04 uses the same quantum states and the same measurement bases with BB84
protocol, but SARG04 can generate secret keys from two-photon pulses when BB84 cannot …

As quantum key distribution progresses into commercial products and services, there is
growing interest in technological solutions that improve performance and/or reduce costs …

We report experimental studies on the effect of the depolarizing quantum channel on weak-
pulse BB84 and SARG04 quantum cryptography. The experimental results show that, in real …

Motivated by the elegant features of a bind signature, we suggest the design of a quantum
blind dual-signature scheme with three phases, ie, initial phase, signing phase and …

В пособии рассматриваются основные принципы и подходы к построению систем
квантовой коммуникации и распределенных защищенных сетей на их основе …
