Parameter estimation and system identification for continuously-observed quantum systems
Hendra I. Nurdin, Madalin Guţǎ
This paper gives an overview of parameter estimation and system identification for quantum input-output systems by continuous observation of the output field. We present recent res…
Multi-parameter estimation beyond Quantum Fisher Information
Rafal Demkowicz-Dobrzanski, Wojciech Gorecki, Madalin Guta
This review aims at gathering the most relevant quantum multi-parameter estimation methods that go beyond the direct use of the Quantum Fisher Information concept. We discuss in de…
A comparative study of estimation methods in quantum tomography
Anirudh Acharya, Theodore Kypraios, Madalin Guta
As quantum tomography is becoming a key component of the quantum engineering toolbox, there is a need for a deeper understanding of the multitude of estimation methods available. H…
Catching and reversing quantum jumps and thermodynamics of quantum trajectories
Juan P. Garrahan, Madalin Guta
A recent experiment by Minev et. al [arXiv:1803.00545] demonstrated that in a dissipative (artificial) 3-level atom with strongly intermittent dynamics it is possible to "catch and…
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…
Quantum filtering for systems driven by fermion fields
J. E. Gough, M. I. Guta, M. R. James +1
Recent developments in quantum technology mean that is it now possible to manipulate systems and measure fermion fields (e.g. reservoirs of electrons) at the quantum level. This pr…
