Characterization of dynamical phase transitions in quantum jump trajectories beyond the properties of the stationary state
Igor Lesanovsky, Merlijn van Horssen, Madalin Guta +1
We describe how to characterize dynamical phase transitions in open quantum systems from a purely dynamical perspective, namely, through the statistical behavior of quantum jump tr…
Asymptotically optimal quantum channel reversal for qudit ensembles and multimode Gaussian states
Peter Bowles, Madalin Guta, Gerardo Adesso
We investigate the problem of optimally reversing the action of an arbitrary quantum channel C which acts independently on each component of an ensemble of n identically prepared d…
Rank-based model selection for multiple ions quantum tomography
Madalin Guta, Theodore Kypraios, Ian Dryden
The statistical analysis of measurement data has become a key component of many quantum engineering experiments. As standard full state tomography becomes unfeasible for large dime…
Large Deviations, Central Limit and dynamical phase transitions in the atom maser
Federico Girotti, Merlijn van Horssen, Raffaella Carbone +1
The theory of quantum jump trajectories provides a new framework for understanding dynamical phase transitions in open systems. A candidate for such transitions is the atom maser,…
The elusive Heisenberg limit in quantum enhanced metrology
Rafal Demkowicz-Dobrzanski, Jan Kolodynski, Madalin Guta
We provide efficient and intuitive tools for deriving bounds on achievable precision in quantum enhanced metrology based on the geometry of quantum channels and semi-definite progr…
