Free Fock parafermions in the tight-binding model with dissipation
A. S. Mastiukova, D. V. Kurlov, V. Gritsev +1
Parafermions that generalize (Majorana or usual) fermions appear as interacting quasi-particles because of their nature. Although attempts to develop models with free (non-interact…
Tomographic and entropic analysis of modulated signals
A. S. Mastiukova, M. A. Gavreev, E. O. Kiktenko +1
We study an application of the quantum tomography framework for the time-frequency analysis of modulated signals. In particular, we calculate optical tomographic representations an…
Probability representation of quantum dynamics using pseudostochastic maps
E. O. Kiktenko, A. O. Malyshev, A. S. Mastiukova +3
In this work, we consider a probability representation of quantum dynamics for finite-dimensional quantum systems with the use of pseudostochastic maps acting on true probability d…
Protecting quantum systems from decoherence with unitary operations
E. O. Kiktenko, A. S. Mastiukova, A. K. Fedorov
Decoherence is a fundamental obstacle to the implementation of large-scale and low-noise quantum information processing devices. In this work, we suggest an approach for suppressin…
