Performance of the subcarrier-wave quantum key distribution in the presence of spontaneous Raman scattering noise generated by classical DWDM channels
Fedor Kiselev, Roman Goncharov, Natalia Veselkova +3
In this paper we study performance of the subcarrier-wave quantum key distribution system (SCW QKD) in the presence of spontaneous Raman scattering (SpRS) noise generated by classi…
Iterative -gate-based protocol for squeezed Schrödinger cat state engineering
Roman Goncharov, N. G. Veselkova, Alexei D. Kiselev
Squeezed optical Schrödinger cat states constitute a key resource for both fundamental tests of quantum theory and up-to-date quantum technologies. We propose a measurement-assiste…
Controlling Hong-Ou-Mandel antibunching via parity governed local spectral shaping of biphoton states
Mikhail Guselnikov, Alexei D. Kiselev, Andrei Gaidash +2
We investigate into experimentally detectable effects such as the Hong-Ou-Mandel (HOM) bunching and antibunching. These regimes can be characterized using the symmetry degree param…
Creation and manipulation of Schrödinger cat states based on semiclassical predictions
N. G. Veselkova, Roman Goncharov, Alexei D. Kiselev
We consider the generation of Schr{ö}dinger cat states using a quantum measurement-induced logical gate where entanglement between the input state of the target oscillator and the…
Lindblad dynamics of open multi-mode bosonic systems: Algebra of bilinear superoperators, exceptional points and speed of evolution
Andrei Gaidash, Alexei D. Kiselev, Anton Kozubov +1
We develop the algebraic method based on the Lie algebra of quadratic combinations of left and right superoperators associated with matrices to study the Lindblad dynamics of multi…
Vulnerabilities of quantum key distribution systems in visible range
Boris Nasedkin, Azat Ismagilov, Vladimir Chistiakov +6
In this paper we investigate spectral vulnerabilities in quantum key distribution systems arising from the use of shorter-wavelength radiation in the 400-800 nm range, with particu…
Quantum repeater via entangled phase modulated multimode coherent states
Roman Goncharov, Alexei D. Kiselev, Fedor Kiselev +4
We present a scheme of quantum repeater that uses entangled multimode coherent states which are obtained by electro-optic modulation of symmetric and antisymmetric Schrödinger cat…
