Towards practical non-Markovianity measures: Normalization and regularization techniques
L. A. Mazhorina, N. D. Korolev, N. V. Morozov +15
Measures characterizing the non-Markovianity degree of the quantum dynamics have several drawbacks when applied to real devices. They depend on the chosen measurement time interval…
Pitfalls of the sublinear QAOA-based factorization algorithm
Sergey V. Grebnev, Maxim A. Gavreev, Evgeniy O. Kiktenko +3
Quantum computing devices are believed to be powerful in solving the prime factorization problem, which is at the heart of widely deployed public-key cryptographic tools. However,…
Controlling quantum many-body systems using reduced-order modelling
I. A. Luchnikov, M. A. Gavreev, A. K. Fedorov
Quantum many-body control is among most challenging problems in quantum science, due to computational complexity of related underlying problems. We propose an efficient approach fo…
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…
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…
Probing non-Markovian quantum dynamics with data-driven analysis: Beyond "black-box" machine learning models
I. A. Luchnikov, E. O. Kiktenko, M. A. Gavreev +3
A precise understanding of the influence of a quantum system's environment on its dynamics, which is at the heart of the theory of open quantum systems, is crucial for further prog…
Lightweight authentication for quantum key distribution
E. O. Kiktenko, A. O. Malyshev, M. A. Gavreev +4
Quantum key distribution (QKD) enables unconditionally secure communication between distinct parties using a quantum channel and an authentic public channel. Reducing the portion o…
