Pseudo entropy from entanglement entropy
Abhigyan Saha, Piotr Sułkowski, Tadashi Takayanagi
Pseudo entropy extends entanglement entropy from a single quantum state to a pair of nonorthogonal states and is generally complex. Taking advantage of Cauchy-Riemann equations, Kr…
Generalised Entanglement Entropies from Unit-Invariant Singular Value Decomposition
Pawel Caputa, Abhigyan Saha, Piotr Sułkowski
We introduce generalisations of von Neumann entanglement entropy that are invariant with respect to certain scale transformations. These constructions are based on the Unit-Invaria…
Musings on SVD and pseudo entanglement entropies
Pawel Caputa, Souradeep Purkayastha, Abhigyan Saha +1
Pseudo-entropy and SVD entropy are generalizations of the entanglement entropy that involve post-selection. In this work we analyze their properties as measures on the spaces of qu…
