Description
I present a quantum extension of the thermodynamic uncertainty relation (TUR) where dynamical fluctuations are quantified by the Terletsky-Margenau-Hill quasiprobability, a quantum generalization of the classical joint probability.
I will explain that the obtained inequality plays a complementary role to existing quantum TURs, focusing on observables' change rather than exchange of charges through jumps and respecting initial coherence.
I also discuss how the quasiprobability TUR enables us to explore a quantum anomalous phenomenon, dissipationless current, recently studied in [Tajima & Funo, PRL (2021)], from the viewpoint of the quasiprobability's non-classicality, without relying on a specific eigenbasis.
