Pygsti

Added

- adds Robust Phase Estimation (RPE) capability
- adds initial support for qutrit reports
- adds tutorials for parallel processing (MPI), gate string reduction, and RPE

Changed

- comments in data set text files can now be carried through to reports
- metadata tables have been added at the end of 'full' and 'general' reports

Added

- adds Randomized Benchmarking support.

Changed

- optimizes and enhances MPI performance.
- improves "general" report to include more analysis.
- updates gauge optimization to be more flexible.
- updates the "standard" 2-qubit germs and fiducials.

Added

- adds timing info and other tweaks to stdout messages

Changed

- performance optimization of reports
- more robust fake data generation

Added

- new "fiducial pair reduction" protocol reduces the number of gate sequences required by GST.

Changed

- converted to Python3 (but backward compatible with Python2.7)
- improvements to germ and fiducial selection algorithms
- expanded options for gauge optimization
- improved code stability & maintenance
- unified stdout printing & progress indicators
- minor bug fixes & performance enhancements

Added

- support for 2-qubit gate set tomography (2Q-GST).
- initial support for parameterized gates & SPAM operations.
- initial support for MPI.

Changed

- cleaner interfaces to objects (GateSet, DataSet, etc.).

Added

- created to test zenodo DOI creation and integration for this project.
