Quantum tomography with wavelet transform in Banach space on Homogeneous space [PDF]
Eeuopean Physical Journal B, 60, 193-201(2007), 2008 The intimate connection between the Banach space wavelet reconstruction method on homogeneous spaces with both singular and nonsingular vacuum vectors, and some of well known quantum tomographies, such as: Moyal-representation for a spin, discrete phase space tomography, tomography of a free particle, Homodyne tomography, phase space tomography and SU ...

Shadow process tomography of quantum channels [PDF]
Phys. Rev. A 107, 042403 (2023), 2021 Quantum process tomography is a critical capability for building quantum computers, enabling quantum networks, and understanding quantum sensors. Like quantum state tomography, the process tomography of an arbitrary quantum channel requires a number of measurements that scale exponentially in the number of quantum bits affected.

Quaternion representation and symplectic spin tomography [PDF]
J. Russ. Laser Res. 34, 477 (2013), 2013 Quantum tomography for continuous variables is based on the symplectic transformation group acting in the phase space. A particular case of symplectic tomography is optical tomography related to the action of a special orthogonal group. In the tomographic description of spin states, the connection between special unitary and special orthogonal groups ...

Quantum Tomography twenty years later [PDF]
Phys. Scripta, 90, 074031 (17 pp) (2015), 2015 A sample of some relevant developments that have taken place during the last twenty years in classical and quantum tomography are displayed. We will present a general conceptual framework that provides a simple unifying mathematical picture for all of them and, as an effective use of it, three subjects have been chosen that offer a wide panorama of the
