Dynamic Cooling on Contemporary Quantum Computers
Autor: Lindsay Bassman Oftelie, Antonella De Pasquale, Michele Campisi
Publikováno v: PRX Quantum, Vol 5, Iss 3, p 030309 (2024)
We study the problem of dynamic cooling whereby a target qubit is cooled at the expense of heating up N−1 further identical qubits by means of a global unitary operation. A standard back-of-the-envelope high-temperature estimate establishes that th

Local quantum thermal susceptibility
Autor: Antonella De Pasquale, Davide Rossini, Rosario Fazio, Vittorio Giovannetti
Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-8 (2016)
In thermodynamics, thermal properties of systems are obtained from averaging procedures which smooth out local details. Here, the authors introduce the concept of local quantum thermal susceptibility, a measure for the best achievable accuracy of est

Degradation and Protection of Entanglement in Open Quantum Systems †
Autor: Antonella De Pasquale
Publikováno v: Proceedings, Vol 12, Iss 1, p 40 (2019)
The distribution of entangled quantum systems among the nodes of a network is a key task at the basis of the development of quantum technologies, e.g., quantum communication, quantum computation, etc. Many efforts have been devoted to identify strate

Building versatile bipartite probes for quantum metrology
Autor: Alessandro Farace, Antonella De Pasquale, Gerardo Adesso, Vittorio Giovannetti
Publikováno v: New Journal of Physics, Vol 18, Iss 1, p 013049 (2016)
We consider bipartite systems as versatile probes for the estimation of transformations acting locally on one of the subsystems. We investigate what resources are required for the probes to offer a guaranteed level of metrological performance, when t

We propose a spatial analog of the Berry's phase mechanism for the coherent manipulation of states of non-relativistic massive particles moving in a two-dimensional landscape. In our construction the temporal modulation of the system Hamiltonian is r

The entanglement survival time is defined as the maximum time a system which is evolving under the action of local Markovian, homogenous in time noise, is capable to preserve the entanglement it had at the beginning of the temporal evolution. In this

We present a new optical scheme enabling the implementation of highly stable and configurable non-Markovian dynamics. Here one photon qubit can circulate in a multipass bulk geometry consisting of two concatenated Sagnac interferometers to simulate t

As the possibility to decouple temporal and spatial variations of the electromagnetic field, leading to a wavelength stretching, has been recognized to be of paramount importance for practical applications, we generalize the idea of stretchability fr
