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…
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…
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 the q…
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…
Quantum Time and the Time-Dilation induced Interaction Transfer mechanism
Dario Cafasso, Nicola Pranzini, Jorge Yago Malo +2
Given a bipartite quantum system in an energy eigenstate, the dynamical description for one component can be derived via entanglement using the other component as a clock. This is…
A formula for the overlap between Generalized Coherent States of any rank one simple Lie algebra
Nicola Pranzini
We provide a formula for computing the overlap between two Generalized Coherent States of any rank one simple Lie algebra. Then, we apply our formula to spin coherent states (i.e.…
On the reliability and accessibility of quantum measurement apparatuses
Nicola Pranzini, Paola Verrucchi
We propose a classification of measurement apparatuses based on their reliability and accessibility. Our notion of reliability parameterises the possibility of getting unexpected w…
Detector-based measurements for QFT: two issues and an AQFT proposal
Nicola Pranzini, Esko Keski-Vakkuri
We present and investigate two issues within the measurement scheme for QFT presented by J. Polo-Gómez, L. J. Garay and E. Martín-Martínez in "A detector-based measurement theory f…
Repeated measurements on non-replicable systems and their consequences for Unruh-DeWitt detectors
Nicola Pranzini, Guillermo García-Pérez, Esko Keski-Vakkuri +1
The Born rule describes the probability of obtaining an outcome when measuring an observable of a quantum system. As it can only be tested by measuring many copies of the system un…
Threshold size for the emergence of a classical-like behaviour
Alessandro Coppo, Nicola Pranzini, Paola Verrucchi
In this work we design a procedure to estimate the minimum size beyond which a system is amenable to a classical-like description, i.e. a description based on representative points…
