Talk on Friday May 05, 2023 at 11:00 Place: IFISC Seminar Room Title: Quantum Fisher Information and its dynamical nature Speaker: Matteo Scandi, ICFO Abstract: <p><strong>MdM Quantum Meeting</strong></p> <p>The importance of the quantum Fisher information metric is testified by the number of applications that this has in very different fields, ranging from hypothesis testing to metrology, passing through thermodynamics. In this presentation, after a small technical introduction of the family of quantum Fisher information, I'll discuss a fact that was overseen in the literature, namely the inherently dynamical nature of Fisher information. This will be exemplified with three examples: first, the equivalence between positivity of a map and the contraction of Fisher information; second, the possibility of defining Markovianity (CP-divisibility) in the same manner; and finally, the definition of detailed balance as self-adjointness with respect to the Fisher information metric.<br /> <br /> The reference for the Markovianity part is:<br /> <a href="https://arxiv.org/pdf/2204.04072.pdf"; target="_blank">https://arxiv.org/pdf/2204.04072.pdf</a></p>; Url event:https://ifisc.uib-csic.es/en/events/seminars/quantum-fisher-information-and-...
