Quantum Process Tomography of a Controlled-NOT Gate [PDF]
Physical Review Letters, 2004 We demonstrate complete characterization of a two-qubit entangling process - a linear optics controlled-NOT gate operating with coincident detection - by quantum process tomography. We use maximum-likelihood estimation to convert the experimental data into a physical process matrix.

Confidence polytopes for quantum process tomography
New Journal of Physics, 2021 In the present work, we propose a generalization of the confidence polytopes approach for quantum state tomography (QST) to the case of quantum process tomography (QPT).

Geoscientific process monitoring with positron emission tomography (GeoPET) [PDF]
Solid Earth, 2016 Transport processes in geomaterials can be observed with input–output experiments, which yield no direct information on the impact of heterogeneities, or they can be assessed by model simulations based on structural imaging using µ-CT.

Simplified quantum process tomography
New Journal of Physics, 2009 We propose and evaluate experimentally an approach to quantum process tomography that completely removes the scaling problem plaguing the standard approach. The key to this simplification is the incorporation of prior knowledge of the class of physical interactions involved in generating the dynamics, which reduces the problem to one of parameter ...

Self-consistent quantum process tomography [PDF]
Physical Review A, 2013 Quantum process tomography is a necessary tool for verifying quantum gates and diagnosing faults in architectures and gate design. We show that the standard approach of process tomography is grossly inaccurate in the case where the states and measurement operators used to interrogate the system are generated by gates that have some systematic error, a ...

Control Systems with Tomographic Sensors—A Review
Sensors, 2022 Industrial process tomography offers two key advantages over conventional sensing systems. Firstly, process tomography systems provide information about 2D or 3D distributions of the variables of interest.
