Robust diagnostics of dark counts for quantum networks
Nikolay Sergeevich Perminov, Maxim Aleksandrovich Smirnov, Konstantin Sergeevich Melnik +5
In this work, we study the timestamps in the registration of single-photon detector counts in quantum communications. The analysis of afterpulse counts on the basis of several appr…
Visual media for monitoring trunk quantum networks
Aleksandr Alekseevich Litvinov, Eugene Mihailovich Katsevman, Oleg Igorevich Bannik +5
In this paper, we formulate ideas for visual media for trunk quantum networks with lines over 100 km. We investigate the local trends analysis of performance parameters for experim…
Noise-immunity Kazan quantum line at 143 km regular fiber link
Oleg I. Bannik, Lenar R. Gilyazov, Artur V. Gleim +6
We experimentally demonstrate a long-distance quantum communication at 143 km between the city of Kazan and the urban-type village of Apastovo in the Republic of Tatarstan by using…
Programmable quantum motherboard for logical qubits
Nikolay Sergeevich Perminov, Diana Yurevna Tarankova, Sergey Andreevich Moiseev
We propose a scheme of a programmable quantum motherboard based on the system of three interacting high-Q resonators coupled with two-level atoms. By using the algebraic methods, w…
RCF-defense for quantum randomness
N. S. Perminov, O. I. Bannik, D. Yu. Tarankova +1
Authors develop new nonparametric methods for verification and monitoring for quantum randomness based on the ranged correlation function (RCF) and a sequence of the ranged amplitu…
Generating pure single-photon states via spontaneous four-wave mixing in a system of coupled microresonators
I. N. Chuprina, N. S. Perminov, D. Yu. Tarankova +1
We present the optimal design for an on-chip single-photon source based on spontaneous four-wave mixing in a system of coupled ring microresonators, which provides frequency uncorr…
