Defect relative entropy in symmetric orbifold CFTs
Mostafa Ghasemi
In this work, we compute the defect relative entropy between topological defects in the symmetric product orbifold CFT . Our analysis covers…
Defect Relative Entropy
Mostafa Ghasemi
Distinguishability is central to quantum information theory, but a quantitative measure for distinguishing topological defects--realizations of generalized symmetries in quantum fi…
Symmetry-Resolved Relative Entropy of Random States
Mostafa Ghasemi
We use large- diagrammatic techniques to calculate the relative entropy of symmetric random states drawn from the Wishart ensemble. These methods are specifically designed for s…
Left-Right Relative Entropy
Mostafa Ghasemi
The concept of distinguishability lies at the heart of quantum information theory. We introduce \textit{left-right relative entropy} as a quantitative measure of distinguishability…
