Algebraic approach for investigation of a multi-mode quantum system dynamics
Andrei Gaidash, Anton Kozubov, Alexei Kiselev +1
We introduce algebraic approach for superoperators that might be useful tool for investigation of quantum (bosonic) multi-mode systems and its dynamics. In order to demonstrate pot…
Continuous-variable quantum key distribution: security analysis with trusted hardware noise against general attacks
Roman Goncharov, Alexei D. Kiselev, Eduard Samsonov +1
In this paper, using the full security framework for continuous variable quantum key distribution (CV-QKD), we provide a composable security proof for the CV-QKD system in a realis…
Hysteresis and Freedericksz thresholds for twisted states in chiral nematic liquid crystals: Minimum-energy path approach
Semen S. Tenishchev, Ivan M. Tambovtcev, Alexei D. Kiselev +1
We study minimum-energy pathways (MEPs) between the branches of metastable helical structures in chiral nematic liquid crystals (CNLCs)subjected to the electric field applied acros…
Coherent detection schemes for subcarrier wave continuous variable quantum key distribution
Eduard Samsonov, Roman Goncharov, Maxim Fadeev +5
We examine different methods to implement coherent detection in the subcarrier wave quantum key distribution (SCW QKD) systems. For classical wavefields, we present the models desc…
Multiple minimum energy paths and scenarios of unwinding transitions in chiral nematic liquid crystals
Semen S. Tenishchev, Alexei D. Kiselev, Aleksei V. Ivanov +1
We apply the minimum energy paths (MEPs) approach to study the helix unwinding transition in chiral nematic liquid crystals. A mechanism of the transition is determined by a MEP pa…
Polarization resolved radiation angular patterns of orientationally ordered nanorods
Alexei D. Kiselev
We employ the transfer matrix approach combined with the Green's function method to theoretically study polarization resolved far-field angular distributions of photoluminescence f…
