Classical and Quantum Information Acquisition
EPJ Web of Conferences, 2014 This paper shows that classical and quantum measurement can be treated on the same foot provided that we make use of effects instead of projectors, of POVM instead ordinary projection measurement, and of amplitude operators instead of amplitudes.

Informationally complete POVM-based shadow tomography
, 2021 Recently introduced shadow tomography protocols use classical shadows of quantum states to predict many target functions of an unknown quantum state. Unlike full quantum state tomography, shadow tomography does not insist on accurate recovery of the density matrix for high rank mixed states. Yet, such a protocol makes multiple accurate predictions with

Minimal orthonormal bases for pure quantum state estimation [PDF]
QuantumWe present an analytical method to estimate pure quantum states using a minimum of three measurement bases in any finite-dimensional Hilbert space. This is optimal as two bases are insufficient to construct an informationally complete positive operator ...

Majorisation‐minimisation algorithm for optimal state discrimination in quantum communications
IET Quantum Communication, Volume 5, Issue 4, Page 612-618, December 2024.A computationally efficient majorisation‐minimisation (MM)‐based algorithm is proposed for solving the optimal quantum state discrimination (QSD) problem in quantum communications applications. The proposed algorithm is significantly faster than the state‐of‐the‐art SDP algorithm for solving QSD problems.
