Quantum master equations and steady states for the ultrastrong-coupling limit and the strong-decoherence limit
Anton Trushechkin
In the framework of theory of open quantum systems, we derive quantum master equations for the ultrastrong system-bath coupling regime and, more generally, the strong-decoherence r…
Derivation of the Redfield quantum master equation and corrections to it by the Bogoliubov method
Anton Trushechkin
Following the ideas N. N. Bogoliubov used to derive the classical and quantum nonlinear kinetic equations, we give an alternative derivation of the Redfield quantum linear master e…
Unified Gorini-Kossakowski-Lindblad-Sudarshan quantum master equation beyond the secular approximation
Anton Trushechkin
Derivation of a quantum master equation for a system weakly coupled to a bath which takes into account nonsecular effects, but nevertheless has the mathematically correct Gorini-Ko…
Security of quantum key distribution with detection-efficiency mismatch in the single-photon case: Tight bounds
M. K. Bochkov, A. S. Trushechkin
One of the challenges in practical quantum key distribution is dealing with efficiency mismatch between different threshold single-photon detectors. There are known bounds for the…
Quantum key distribution protocol with pseudorandom bases
A. S. Trushechkin, P. A. Tregubov, E. O. Kiktenko +2
Quantum key distribution (QKD) offers a way for establishing information-theoretically secure communications. An important part of QKD technology is a high-quality random number ge…
Measurement-assisted Landau-Zener transitions
A. N. Pechen, A. S. Trushechkin
Nonselective quantum measurements, i.e., measurements without reading the results, are often considered as a resource for manipulating quantum systems. In this work, we investigate…
