Boosting quantum key distribution via the end-to-end loss control
A. D. Kodukhov, V. A. Pastushenko, N. S. Kirsanov +3
With the rise of quantum technologies, data security increasingly relies on quantum cryptography and its most notable application, quantum key distribution (QKD). Yet, current tech…
Improving the performance of quantum cryptography by using the encryption of the error correction data
Valeria A. Pastushenko, Dmitry A. Kronberg
Security of quantum key distribution (QKD) protocols relies solely on quantum physics laws, namely, on the impossibility to distinguish between non-orthogonal quantum states with a…
Forty Thousand Kilometers Under Quantum Protection
N. S. Kirsanov, V. A. Pastushenko, A. D. Kodukhov +5
Quantum key distribution (QKD) is a revolutionary cryptography response to the rapidly growing cyberattacks threat posed by quantum computing. Yet, the roadblock limiting the vast…
Boosting quantum key distribution via the end-to-end physical control
A. D. Kodukhov, V. A. Pastushenko, N. S. Kirsanov +4
Quantum key distribution (QKD) is a cornerstone of the secure quantum encryption. Building on the quantum irreversibility, we develop a technique reborning the existing QKDs into p…
Long-distance quantum key distribution based on the physical loss control
N. S. Kirsanov, N. R. Kenbaev, A. B. Sagingalieva +3
Existing quantum cryptography is resistant against secrecy-breaking quantum computers but suffers fast decay of the signal at long distances. The various types of repeaters of prop…
Security of the decoy state method for quantum key distribution
A. S. Trushechkin, E. O. Kiktenko, D. A. Kronberg +1
Quantum cryptography or, more precisely, quantum key distribution (QKD), is one of the advanced areas in the field of quantum technologies. The confidentiality of keys distributed…
Quantum soft filtering for the improved security analysis of the coherent one-way quantum-key-distribution protocol
D. A. Kronberg, A. S. Nikolaeva, Y. V. Kurochkin +1
A precise security analysis of practical quantum key distribution (QKD) systems is an important step for improving their performance. Here we consider a class of quantum soft filte…
Analysis of coherent quantum cryptography protocol vulnerability to an active beam-splitting attack
D. A. Kronberg, E. O. Kiktenko, A. K. Fedorov +1
We consider a new type of attack on a coherent quantum key distribution protocol [coherent one-way (COW) protocol]. The main idea of the attack consists in measuring individually t…
