Resource-efficient quantum correlation measurements via multicopy neural network methods

Patrycja Tulewicz, Karol Bartkiewicz, Adam Miranowicz +1

Measuring complex properties in quantum systems, such as measures of quantum entanglement and Bell nonlocality, is inherently challenging. Traditional methods, like quantum state t…

Quantumness and its hierarchies in PT-symmetric down-conversion models

Jan Peřina, Karol Bartkiewicz, Grzegorz Chimczak +4

We investigate the hierarchy of quantum correlations in a quadratic bosonic parity-time-symmetric system (PTSS) featuring distinct dissipation and amplification channels. The hiera…
