Learning entanglement breakdown as a phase transition by confusion

no code implementations1 Feb 2022 M. A. Gavreev, A. S. Mastiukova, E. O. Kiktenko, A. K. Fedorov

Then we extend the way of using the 'learning by confusion' scheme for recognizing whether an arbitrary given state is entangled or separable.

Learning phase transitions in ferrimagnetic GdFeCo alloys

1 code implementation19 Oct 2020 N. A. Koritsky, S. V. Solov'yov, A. K. Fedorov, A. K. Zvezdin

The approach for finding phase transitions in the system is based on the `learning by confusion' scheme, which allows one to characterize phase transitions using a universal $W$-shape.

Tomographic and entropic analysis of modulated signals

no code implementations20 Jan 2020 A. S. Mastiukova, M. A. Gavreev, E. O. Kiktenko, A. K. Fedorov

We study an application of the quantum tomography framework for the time-frequency analysis of modulated signals.

Experimental quantum homodyne tomography via machine learning

no code implementations15 Jul 2019 E. S. Tiunov, V. V. Tiunova, A. E. Ulanov, A. I. Lvovsky, A. K. Fedorov

Complete characterization of states and processes that occur within quantum devices is crucial for understanding and testing their potential to outperform classical technologies for communications and computing.

Lightweight authentication for quantum key distribution

no code implementations25 Mar 2019 E. O. Kiktenko, A. O. Malyshev, M. A. Gavreev, A. A. Bozhedarov, N. O. Pozhar, M. N. Anufriev, A. K. Fedorov

Reducing the portion of quantum-generated secret keys, that is consumed during the authentication procedure, is of significant importance for improving the performance of QKD systems.
