In this note we obtain commutativity criteria for normal compact operators using the projective spectrum. We thus improve a corresponding result obtained by Chagouel, Stessin and Zhu in Trans. Amer.

Researchers explored the connection between the quantum speed limit (QSL) and time resolution in quantum sensing, particularly through Ramsey interferometry. They established that the best ...
