Bayes estimator for multinomial parameters and Bhattacharyya distances
Christopher Ferrie, Robin Blume-Kohout
We derive the Bayes estimator for the parameters of a multinomial distribution under two loss functions ( and ) that are based on the Bhattacharyya coefficient $B(\vec{…
QInfer: Statistical inference software for quantum applications
Christopher Granade, Christopher Ferrie, Ian Hincks +5
Characterizing quantum systems through experimental data is critical to applications as diverse as metrology and quantum computing. Analyzing this experimental data in a robust and…
Explaining quantum correlations through evolution of causal models
Robin Harper, Robert J. Chapman, Christopher Ferrie +5
We propose a framework for the systematic and quantitative generalization of Bell's theorem using causal networks. We first consider the multi-objective optimization problem of mat…
Practical adaptive quantum tomography
Christopher Granade, Christopher Ferrie, Steven T. Flammia
We introduce a fast and accurate heuristic for adaptive tomography that addresses many of the limitations of prior methods. Previous approaches were either too computationally inte…
Experimental Demonstration of Self-Guided Quantum Tomography
Robert J. Chapman, Christopher Ferrie, Alberto Peruzzo
Robust, accurate and efficient quantum tomography is key for future quantum technologies. Traditional methods are impractical for even medium sized systems and are not robust again…
