Quantum estimation of coupling strengths in driven-dissipative optomechanics
Kamila Sala, Anton Doicin, Andrew D. Armour +1
We exploit local quantum estimation theory to investigate the measurement of linear and quadratic coupling strengths in a driven-dissipative optomechanical system. For experimental…
General expressions for the quantum Fisher information matrix with applications to discrete quantum imaging
Lukas J. Fiderer, Tommaso Tufarelli, Samanta Piano +1
The quantum Fisher information matrix is a central object in multiparameter quantum estimation theory. It is usually challenging to obtain analytical expressions for it because mos…
Single Quantum Emitter Dicke Enhancement
Tommaso Tufarelli, Daniel Friedrich, Heiko Groß +3
Coupling identical emitters to the same field mode is well-established method to enhance light matter interaction. However, the resulting boost of the coupling stren…
Refined diamond norm bounds on the emergence of objectivity of observables
Eugenia Colafranceschi, Ludovico Lami, Gerardo Adesso +1
The theory of Quantum Darwinism aims to explain how our objective classical reality arises from the quantum world, by analysing the distribution of information about a quantum syst…
