Selective and efficient quantum state tomography and its application to quantum process tomography
(American Physical Society, 2013-01-18)
We present a method for quantum state tomography that enables the efficient estimation, with fixed precision, of any of the matrix elements of the density matrix of a state, provided that the states from the basis in which ...
An application of the maximum entropy method with smoothing to industrial tomography
(Planta Piloto de Ingeniería Química, 2013-10)
The maximum entropy method combined with a smoothing restriction was applied to the tomography of a BNC connector using five noisy radiographies from different rotating views. A heuristic control of the filter parameter ...
A new bi-imaging NDT system for simultaneous recovery of attenuation and electronic density maps
(Confédération Française pour les Essais Non Destructifs, 2020)
Computed Tomography is a widely used imaging technique for non-destructive testing and evaluation in industry. Tomographic modalities exploit only primary radiation, which is non-deviated but attenuated radiation going ...
Selective and efficient quantum process tomography
(American Physical Society, 2009-09)
In this paper we describe in detail and generalize a method for quantum process tomography that was presented by Bendersky [Phys. Rev. Lett. 100, 190403 (2008)]. The method enables the efficient estimation of any element ...
Software-defined optoacoustic tomography
(Optical Society of America, 2020-01)
In this work we present what we believe is the first application of software-defined optoelectronics (SDO) for bidimensional optoacoustic tomography (OAT). The SDO concept refers to optoelectronic systems where the ...
On the identification of piecewise constant coefficients in optical diffusion tomography by level set
(EDP Sciences, 2017-04)
In this paper, we propose a level set regularization approach combined with a split strategy for the simultaneous identification of piecewise constant diffusion and absorption coefficients from a finite set of optical ...
Coronary microvascular dysfunction in women with nonobstructive ischemic heart disease as assessed by positron emission tomography
(AME Publishing Company, 2017-03)
Traditional approaches for risk assessment of ischemic heart disease (IHD) are based on the physiological consequences of an epicardial coronary stenosis. Of note, normal coronary arteries or nonobstructive coronary artery ...
