Current fluctuations in open quantum systems: Bridging the gap between quantum continuous measurements and full counting statistics

GT Landi, MJ Kewming, MT Mitchison, PP Potts - PRX Quantum, 2024 - APS
Continuously measured quantum systems are characterized by an output current, in the form
of a stochastic and correlated time series, which conveys crucial information about the …

Work fluctuations in slow processes: quantum signatures and optimal control

HJD Miller, M Scandi, J Anders, M Perarnau-Llobet - Physical review letters, 2019 - APS
An important result in classical stochastic thermodynamics is the work fluctuation-dissipation
relation (FDR), which states that the dissipated work done along a slow process is …

formalism predicts correlations between different spin components that would correspond to …

How Single-Photon Switching is Quenched with Multiple –Level Atoms

AN Poddubny, S Rosenblum, B Dayan - Physical Review Letters, 2024 - APS
Single-photon nonlinearity, namely, the change in the response of the system as the result of
the interaction with a single photon, is generally considered an inherent property of a single …

Time-reversal symmetric work distributions for closed quantum dynamics in the histories framework

HJD Miller, J Anders - New Journal of Physics, 2017 - iopscience.iop.org
