Physicality of evolution and statistical contractivity are equivalent notions of maps
Matteo Scandi, Paolo Abiuso, Dario De Santis +1
Statistical quantifiers are generically required to contract under physical evolutions, following the intuition that information should be lost under noisy transformations. This pr…
A Theory of Inaccessible Information
Jacopo Surace
What would be the consequences if there were fundamental limits to our ability to experimentally explore the world? In this work we seriously consider this question. We assume the…
Quantum Fisher Information and its dynamical nature
Matteo Scandi, Paolo Abiuso, Jacopo Surace +1
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 metrol…
Characterizing (non-)Markovianity through Fisher Information
Paolo Abiuso, Matteo Scandi, Dario De Santis +1
A non-isolated physical system typically loses information to its environment, and when such loss is irreversible the evolution is said to be Markovian. Non-Markovian effects are s…
State retrieval beyond Bayes' retrodiction
Jacopo Surace, Matteo Scandi
In the context of irreversible dynamics, associating to a physical process its intuitive reverse can result to be a quite ambiguous task. It is a standard choice to define the reve…
Fermionic Gaussian states: an introduction to numerical approaches
Jacopo Surace, Luca Tagliacozzo
This document is meant to be a practical introduction to the analytical and numerical manipulation of Fermionic Gaussian systems. Starting from the basics, we move to relevant mode…
