Near-optimal quantum tomography: estimators and bounds
We give bounds on the average fidelity achievable by any quantum state estimator, which is arguably the most prominently used figure of merit in quantum state tomography. Moreover, these bounds can be computed online—that is, while the experiment is running. We show numerically that these bounds are...
