Generalized overlap quantum state tomography*
Physical Review Research, 2020 We propose and experimentally demonstrate a quantum state tomography protocol that generalizes and improves upon the Wallentowitz-Vogel-Banaszek-Wódkiewicz point-by-point Wigner function reconstruction.

Quantum Error Mitigation for Quantum State Tomography [PDF]
IEEE Access, 2021 Quantum state tomography (QST) is the task of statistically constructing the density matrix of an unknown quantum state by measuring its several copies. The presence of noise in the QST setup can considerably degrade the fidelity between the constructed ...
