What is a quantum cryptography protocol that ensures the maximum distance in the case of a strictly single-photon source?
2015 · Journal of Experimental and Theoretical Physics Letters
The distance of secret key distribution in the case of a strictly single-photon source has been analyzed for the BB84 protocol and phase time coding (the PTC protocol) protocols. It has been shown that the …

On a New Attack on Quantum Key Distribution: Joint Unambiguous Measurements of Probe States and the PNS Attack on Information States
2020 · Journal of Experimental and Theoretical Physics Letters
A new attack on the quantum key distribution is proposed involving joint collective unambiguous measurements of reflected probe states from an intensity modulator and photon number splitting (PNS) measurements, i.e., nondestructive measurements of the number …

Robustness of Quantum Cryptography Systems with Phase–Time Coding against Active Probing Attacks
2020 · Journal of Experimental and Theoretical Physics
Abstract The robustness of a quantum cryptography system is considered that uses a protocol with phase–time coding on attenuated coherent states. This protocol admits an effective fiber optic implementation, which does not require a phase …

On the Key Search Complexity in Quantum Cryptography with Strong Information-Theoretic Authentication
2025 · Journal of Experimental and Theoretical Physics Letters
The stability of quantum key distribution systems is based not only on the detection of attacks on quantum states, which is guaranteed by the fundamental quantum theory laws, but also on ensuring the integrity of …
