Applicability of QKD: TerraQuantum view on the NSA's scepticism
D. Sych, A. Kodukhov, V. Pastushenko +3
Quantum communication offers unique features that have no classical analog, in particular, it enables provably secure quantum key distribution (QKD). Despite the benefits of quantu…
Experimental demonstration of scalable quantum key distribution over a thousand kilometers
A. Aliev, V. Statiev, I. Zarubin +10
Secure communication over long distances is one of the major problems of modern informatics. Classical transmissions are recognized to be vulnerable to quantum computer attacks. Re…
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…
Linear Ascending Metrological Algorithm
M. R. Perelshtein, N. S. Kirsanov, V. V. Zemlyanov +4
The ubiquitous presence of shot noise sets a fundamental limit to the measurement precision in classical metrology. Recent advances in quantum devices and novel quantum algorithms…
Phase estimation algorithm for the multibeam optical metrology
V. V. Zemlyanov, N. S. Kirsanov, M. R. Perelshtein +5
Unitary Fourier transform lies at the core of the multitudinous computational and metrological algorithms. Here we show experimentally how the unitary Fourier transform-based phase…
H-theorem and Maxwell Demon in Quantum Physics
N. S. Kirsanov, A. V. Lebedev, I. A. Sadovskyy +4
The Second Law of Thermodynamics states that temporal evolution of an isolated system occurs with non-diminishing entropy. In quantum realm, this holds for energy-isolated systems…
Entropy Dynamics in the System of Interacting Qubits
N. S. Kirsanov, A. V. Lebedev, M. V. Suslov +3
The classical Second Law of Thermodynamics demands that an isolated system evolves with a non-diminishing entropy. This holds as well in quantum mechanics if the evolution of the e…
