Would quantum coherence be increased by curvature effect in de Sitter space? [PDF]
Journal of High Energy Physics, 2023 We study the quantum coherence in de Sitter space for the bipartite system of Alice and Bob who initially share an entangled state between the two modes of a free massive scalar field.

The coherence of light is fundamentally tied to the quantum coherence of the emitting particle. [PDF]
Sci Adv, 2021 Investigating light emission by free charged particles through the prism of quantum optics can unveil the emitter wave function. Coherent emission of light by free charged particles is believed to be successfully captured by classical electromagnetism in

One classical bit perspective on the noisy teleportation of quantum coherence [PDF]
Scientific ReportsQuantum teleportation of an unknown quantum state necessitates the transmission of two classical bits of information; however, when the quantum state is partially known, only a single classical bit is required for the teleportation of its quantum ...

Quantifying quantum coherence via Kirkwood-Dirac quasiprobability [PDF]
Physical Review A, 2023 Kirkwood-Dirac (KD) quasiprobability is a quantum analog of phase space probability of classical statistical mechanics, allowing negative or/and nonreal values. It gives an informationally complete representation of a quantum state.
