Quantum Darwinism and the quality of Petz recovery
Juha Torvinen, Esko Keski-Vakkuri, Nicola Pranzini
According to Quantum Darwinism, system-environment interactions both einselect particular system properties and encode them redundantly in many independent subsets of the environme…
Induced Resource Theories and Harvesting via Quantum Probes
Ron Nyström, Simone Cepollaro, Nicola Pranzini +3
We consider scenarios in which a quantum system with a well-defined resource theory is used as a probe to interact with an environment, such as a quantum field, for which a resourc…
Detector-based measurement-induced state updates in AdS/CFT
Vijay Balasubramanian, Esko Keski-Vakkuri, Nicola Pranzini
Conventional understandings of quantum theory hold that measurements change the state of an observed system following the Lüders update rule. Textbooks describe the application of…
Quantum model for black holes and clocks
Alessandro Coppo, Nicola Pranzini, Paola Verrucchi
We consider a stationary quantum system consisting of two non-interacting yet entangled subsystems, and . We identify a quantum theory characterizing such that, in th…
Gravitational quantum speed limit
Nicola Pranzini, Lorenzo Maccone
While playing an important role in the foundations of quantum theory, Quantum Speed Limits (QSL) have no role in discussions about the search for quantum gravity. We fill this gap…
Harvesting magic from the vacuum
Ron Nyström, Nicola Pranzini, Esko Keski-Vakkuri
Magic is the quantum resource allowing a quantum computer to perform operations that cannot be simulated efficiently by classical computation. As such, generating magic in a quantu…
