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…

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…

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…
