Coherent regime of Kapitza-Dirac effect with electrons
Kamila Moriová, Petr Koutenský, Neli Laštovičková Streshkova +5
Electron matter waves coherently diffract when passing through a periodic structure of light formed by two interfering light waves. In this so-called Kapitza-Dirac effect, the elec…

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…

Conditional mutual information: A generalization of causal inference in quantum systems
Anupam Ghosh
The concept of causality is fundamental to numerous scientific explanations; however, its extension to the quantum regime has yet to be rigorously explored. This letter introduces…
