Maximum likelihood quantum state tomography is inadmissible
Christopher Ferrie, Robin Blume-Kohout
Maximum likelihood estimation (MLE) is the most common approach to quantum state tomography. In this letter, we investigate whether it is also optimal in any sense. We show that ML…
Minimax quantum state estimation under Bregman divergence
Maria Quadeer, Marco Tomamichel, Christopher Ferrie
We investigate minimax estimators for quantum state tomography under general Bregman divergences. First, generalizing the work of Komaki et al. $\href{http://dx.doi.org/10.3390/e19…
Efficient online quantum state estimation using a matrix-exponentiated gradient method
Akram Youssry, Christopher Ferrie, Marco Tomamichel
In this paper, we explore an efficient online algorithm for quantum state estimation based on a matrix-exponentiated gradient method previously used in the context of machine learn…
