Quantum optical reset with classical memory
Evgeniy O. Kiktenko, Oleg M. Sotnikov, Ilia A. Iakovlev +5
Dynamic quantum circuits generate states that depend on the measurement results obtained during circuit execution. To date such a quantum computing model has mainly been implemente…
Brute-force positivization of model ground states
P. A. Bannykh, O. M. Sotnikov, V. V. Mazurenko
Exploring sign structures of quantum wave functions attracts considerable attention due to the potential for advances in modeling complex phases of matter. This stimulates developi…
Emergence of global receptive fields capturing multipartite quantum correlations
Oleg M. Sotnikov, Ilia A. Iakovlev, Evgeniy O. Kiktenko +3
In quantum physics, even simple data with a well-defined structure at the wave function level can be characterized by extremely complex correlations between its constituent element…
Exploring entanglement in finite-size quantum systems with degenerate ground state
V. S. Okatev, O. M. Sotnikov, V. V. Mazurenko
We develop an approach for characterizing non-local quantum correlations in spin systems with exactly or nearly degenerate ground states. Starting with linearly independent degener…
Achieving the volume-law entropy regime with random-sign Dicke states
Oleg M. Sotnikov, Ilia A. Iakovlev, Evgeniy O. Kiktenko +2
Manipulating entanglement, which reflects non-local correlations in a quantum system and defines the complexity of describing its wave function, represents the extremely tough chal…
