Superior resilience of non-Gaussian entanglement against local Gaussian noises
Sergey Filippov, Alena Termanova
Entanglement distribution task encounters a problem of how the initial entangled state should be prepared in order to remain entangled the longest possible time when subjected to l…
Proof of the Gaussian maximizers conjecture for the communication capacity of noisy heterodyne measurements
A. S. Holevo, S. N. Filippov
Basing on recently developed convex programming framework in the paper [arXiv:2204.10626], we provide a proof for a long-standing conjecture on optimality of Gaussian encondings fo…
Multipartite correlations in quantum collision models
Sergey N. Filippov
Quantum collision models have proved to be useful for a clear and concise description of many physical phenomena in the field of open quantum systems: thermalization, decoherence,…
Collisional open quantum dynamics with a generally correlated environment: Exact solvability in tensor networks
Sergey N. Filippov, Ilia A. Luchnikov
Quantum collision models are receiving increasing attention as they describe many nontrivial phenomena in dynamics of open quantum systems. In a general scenario of both fundamenta…
Entanglement robustness in trace decreasing quantum dynamics caused by depolarization and polarization dependent losses
Sergey N. Filippov
Trace decreasing dynamical maps are as physical as trace preserving ones; however, they are much less studied. Here we overview how the quantum Sinkhorn theorem can be successfully…
Multipartite entanglement to boost superadditivity of coherent information in quantum communication lines with polarization dependent losses
Sergey N. Filippov
Coherent information quantifies the achievable rate of the reliable quantum information transmission through a communication channel. Use of the correlated quantum states instead o…
