Fast quantum measurement tomography with optimal error bounds
A projected least-squares quantum measurement tomography protocol is shown to achieve dimension-optimal sample complexity (up to log factors) for worst-case and average-case distances, with a provable gap in the number-of-outcomes scaling.
