Unification of observational entropy with maximum entropy principles
Joseph Schindler, Philipp Strasberg, Niklas Galke +2
We introduce a definition of coarse-grained entropy that unifies measurement-based (observational entropy) and max-entropy-based (Jaynes) approaches to coarse-graining, by identify…

Two-particle quantum interference in a nonlinear optical medium: a witness of timelike indistinguishability
Chao Chen, Shu-Tian Xue, Yu-Peng Shi +8
The Hong-Ou-Mandel effect is a paradigmatic quantum phenomenon demonstrating the interference of two indistinguishable photons that are linearly coupled at a 50:50 beam splitter. H…
