Quantum Limits of Passive Optical Surface Metrology and Defect Detection
Jernej Frank, George Brumpton, Tommaso Tufarelli +2
We develop a quantum statistical framework for passive optical surface metrology. Modelling a surface as an incoherent ensemble of point emitters imaged through a diffraction-limit…
Looking down the rabbit hole: Towards quantum optimal estimation of surface roughness
Quentin Muller, Tommaso Tufarelli, Madalin Guta +3
Surface roughness is an important quantity to many engineering and precision manufacturing disciplines. In this paper we investigate the problem of estimating the root-mean-square…
Multilevel Quantum Rabi Models
Tabitha Doicin, Andrew D. Armour, Tommaso Tufarelli
The quantum Rabi model, which describes the interaction between a simplified atom and a mode of the electromagnetic field, is a cornerstone of modern quantum optics. One of the key…
Ergodiscord: An Operational and Distinct Notion of Quantumness of Correlations
Mir Alimuddin, Snehasish Roy Chowdhury, Ram Krishna Patra +4
Nonclassicality in composite quantum systems depicts several puzzling manifestations, with Einstein-Podolsky-Rosen entanglement, Schrödinger steering, and Bell nonlocality being th…
Anticrossing of a plasmonic nanoresonator mode and a single quantum dot at room temperature
Daniel Friedrich, Jin Qin, Benedikt Schurr +3
Room-temperature strong coupling of a single quantum emitter and a single resonant plasmonic mode is a key resource for quantum information processing and quantum sensing at ambien…
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…
