Low frequency signal detection via correlated Ramsey measurements
Santiago Oviedo-Casado, Javier Prior, Javier Cerrillo
The low frequency region of the spectrum is a challenging regime for quantum probes. We support the idea that, in this regime, performing Ramsey measurements carefully controlling…
Periodically refreshed quantum thermal machines
Archak Purkayastha, Giacomo Guarnieri, Steve Campbell +2
We introduce unique class of cyclic quantum thermal machines (QTMs) which can maximize their performance at the finite value of cycle duration where they are most irreversible.…
Zero- and Low-Field Sensing with Nitrogen Vacancy Centers
Philipp J. Vetter, Alastair Marshall, Genko T. Genov +8
Over the years, an enormous effort has been made to establish nitrogen vacancy (NV) centers in diamond as easily accessible and precise magnetic field sensors. However, most of the…
Periodically refreshed baths to simulate open quantum many-body dynamics
Archak Purkayastha, Giacomo Guarnieri, Steve Campbell +2
Obtaining dynamics of an interacting quantum many-body system connected to multiple baths initially at different, finite, temperatures and chemical potentials is a challenging prob…
Conformal Properties of Hyperinvariant Tensor Networks
Matthew Steinberg, Javier Prior
Hyperinvariant tensor networks (hyMERA) were introduced as a way to combine the successes of perfect tensor networks (HaPPY) and the multiscale entanglement renormalization ansatz…
Charging a quantum battery with linear feedback control
Mark T. Mitchison, John Goold, Javier Prior
Energy storage is a basic physical process with many applications. When considering this task at the quantum scale, it becomes important to optimise the non-equilibrium dynamics of…
