Reflected entropy and computable cross-norm negativity: Free theories and symmetry resolution

C Berthiere, G Parez - Physical Review D, 2023 - APS
We investigate a separability criterion based on the computable cross-norm (CCNR), and a
related quantity called the CCNR negativity. We introduce a reflected version of the CCNR …

Reflected entropy: Not a correlation measure

P Hayden, M Lemm, J Sorce - Physical Review A, 2023 - APS
By explicit counterexample, we show that the “reflected entropy” defined by Dutta and
Faulkner is not monotonically decreasing under partial trace, and so is not a measure of …
