Comment on "Quantum Limits to Incoherent Imaging are Achieved by Linear Interferometry"
George Brumpton, Aiman Khan, Helia Hooshmand +2
We show that the construction of the linear interferometer in the Supplemental Material of arXiv:1909.09581 is flawed, leading to a generally suboptimal solution. We then provide t…
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…
Deep Learning-based Single-Shot Composite Fringe Projection Profilometry with Pixel-Wise Uncertainty Quantification
Xiangjun Kong, Qingkang Bao, Tibebe Yalew +2
Driven by the growing demand for high-speed 3D measurement in advanced manufacturing, optical metrology algorithms must deliver high accuracy and robustness under dynamic condition…
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…
Towards superresolution surface metrology: Quantum estimation of angular and axial separations
Carmine Napoli, Samanta Piano, Richard Leach +2
We investigate the localization of two incoherent point sources with arbitrary angular and axial separations in the paraxial approximation. By using quantum metrology techniques, w…
Enhanced Raman sideband cooling of caesium atoms in a vapour-loaded magneto-optical trap
Y. Li, J. Wu, G. Feng +6
We report enhanced three-dimensional degenerated Raman sideband cooling (3D DRSC) of caesium (Cs) atoms in a standard single-cell vapour-loading magneto-optical trap. Our improved…
Genuine tripartite entanglement and nonlocality in Bose-Einstein condensates by collective atomic recoil
Samanta Piano, Gerardo Adesso
We study a system represented by a Bose-Einstein condensate interacting with a cavity field in presence of a strong off-resonant pumping laser. This system can be described by a th…
Theory of genuine tripartite nonlocality of Gaussian states
Gerardo Adesso, Samanta Piano
We investigate the genuine multipartite nonlocality of three-mode Gaussian states of continuous variable systems. For pure states, we present a simplified procedure to obtain the m…
Analysing surface structures on (Ga,Mn)As by Atomic Force Microscopy
S. Piano, A. W. Rushforth, K. W. Edmonds +3
Using atomic force microscopy, we have studied the surface structures of high quality molecular beam epitaxy grown (Ga,Mn)As compound. Several samples with different thickness and…
