Reservoir Support Sets the Minimum Loss for Non-Hermitian Dynamics
Alena Mastiukova
The minimum loss required to reproduce non-Hermitian dynamics depends on how many physical modes each reservoir can address coherently. Established positive-matrix criteria bound t…
Regularizing quantum loss landscapes by noise injection
Daniil S. Bagaev, Maxim A. Gavreev, Alena S. Mastiukova +2
The difficulty of training variational quantum algorithms and quantum machine learning models is well established. In particular, quantum loss landscapes are often highly non-conve…
Quantum-inspired optimization for wavelength assignment
Aleksey S. Boev, Sergey R. Usmanov, Alexander M. Semenov +5
Problems related to wavelength assignment (WA) in optical communications networks involve allocating transmission wavelengths for known transmission paths between nodes that minimi…
Suppressing decoherence in quantum state transfer with unitary operations
Maxim A. Gavreev, Evgeniy O. Kiktenko, Alena S. Mastiukova +1
Decoherence is the fundamental obstacle limiting the performance of quantum information processing devices. The problem of transmitting a quantum state (known or unknown) from one…
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…
Multiclass classification using quantum convolutional neural networks with hybrid quantum-classical learning
Denis Bokhan, Alena S. Mastiukova, Aleksey S. Boev +2
Multiclass classification is of great interest for various applications, for example, it is a common task in computer vision, where one needs to categorize an image into three or m…
Learning entanglement breakdown as a phase transition by confusion
M. A. Gavreev, A. S. Mastiukova, E. O. Kiktenko +1
Quantum technologies require methods for preparing and manipulating entangled multiparticle states. However, the problem of determining whether a given quantum state is entangled o…
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…
