Thermodynamics of decoherence
Maria Popovic, Mark T. Mitchison, John Goold
We investigate the nonequilibrium thermodynamics of pure decoherence. In a pure decoherence process, the system Hamiltonian is a constant of motion and there is no direct energy ex…
Quantum heat statistics with time-evolving matrix product operators
Maria Popovic, Mark T. Mitchison, Aidan Strathearn +3
We present a numerically exact method to compute the full counting statistics of heat transfer in non-Markovian open quantum systems, which is based on the time-evolving matrix pro…
Precursors of non-Markovianity
Steve Campbell, Maria Popovic, Dario Tamascelli +1
Using the paradigm of information backflow to characterize a non-Markovian evolution, we introduce so-called precursors of non-Markovianity, i.e. necessary properties that the syst…
Entropy production and correlations in a controlled non-Markovian setting
Maria Popovic, Bassano Vacchini, Steve Campbell
We study the relationship between (non-)Markovian evolutions, established correlations, and the entropy production rate. We consider a system qubit in contact with a thermal bath a…
Phase estimation with squeezed single photons
Stefano Olivares, Maria Popovic, Matteo G. A. Paris
We address the performance of an interferometric setup in which a squeezed single photon interferes at a beam splitter with a coherent state. Our analysis in based on both the quan…
