Classifying single-qubit noise using machine learning

no code implementations30 Aug 2019 Travis L. Scholten, Yi-Kai Liu, Kevin Young, Robin Blume-Kohout

Quantum characterization, validation, and verification (QCVV) techniques are used to probe, characterize, diagnose, and detect errors in quantum information processors (QIPs).

Recovering quantum gates from few average gate fidelities

1 code implementation1 Mar 2018 Ingo Roth, Richard Kueng, Shelby Kimmel, Yi-Kai Liu, David Gross, Jens Eisert, Martin Kliesch

For the important case of characterising multi-qubit unitary gates, we provide a rigorously guaranteed and practical reconstruction method that works with an essentially optimal number of average gate fidelities measured respect to random Clifford unitaries.

A Spectral Algorithm for Latent Dirichlet Allocation

no code implementations NeurIPS 2012 Anima Anandkumar, Dean P. Foster, Daniel J. Hsu, Sham M. Kakade, Yi-Kai Liu

This work provides a simple and efficient learning procedure that is guaranteed to recover the parameters for a wide class of topic models, including Latent Dirichlet Allocation (LDA).
