Optimal estimation of quantum processes using incomplete information: variational quantum process tomography
Thiago O. Maciel, Reinaldo O. Vianna
We develop a quantum process tomography method, which variationally reconstruct the map of a process, using noisy and incomplete information about the dynamics. The new method enco…
Fast entanglement detection for unknown states of two spatial qutrits
G. Lima, E. S. Gómez, A. Vargas +2
We investigate the practicality of the method proposed by Maciel et al. [Phys. Rev. A. 80, 032325(2009)] for detecting the entanglement of two spatial qutrits (3-dimensional quantu…
Variational quantum tomography with incomplete information by means of semidefinite programs
Thiago O. Maciel, André T. Cesário, Reinaldo O. Vianna
We introduce a new method to reconstruct unknown quantum states out of incomplete and noisy information. The method is a linear convex optimization problem, therefore with a unique…
