Energetics in daemonic work extraction protocols via non-ideal QND-energy measurement
Daniele Morrone, Francesco Albarelli, Vittorio Giovannetti +2
We address the problem of extracting work from a quantum system assisted by a quantum non-demolition (QND) energy measurement. When a perfect QND measurement can be performed and a…
Formal Integration of Electron Scattering Processes via Separation of Dynamical and Geometric Contributions
Lorenzo Bagnasacco, Fabio Taddei, Vittorio Giovannetti
By decoupling the geometric from the dynamical contributions in the scattering processes, we develop a method to compute the scattering matrix of electrons in a one-dimensional coh…
Quantum illumination advantage in quantum Doppler radar
Rongyu Wei, Francesco Albarelli, Jun Li +1
A Doppler radar is a device that employs the Doppler effect to estimate the radial velocity of a moving target at a distance. Traditional radars are based on a classical descriptio…
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…
