auspex 2020.1

Scientific measurement platform specifically geared towards superconducting qubit measurements.

Auspex, the automated system for python-based experiments, is a framework for performing laboratory measurements. Auspex was developed by a group that primarily performs measurements on superconducting qubits and magnetic memory elements, but its underpinnings are sufficiently general to allow for extension to arbitrary equipment and experiments. Using several layers of abstraction, we attempt to meet the following goals:

1. Instrument drivers should be easy to write.
2. Measurement code should be flexible and reusable.
3. Data acquisition and processing should be pipelined, asynchronous, and reconfigurable.
4. Experiments should be adaptive, not always pre-defined.

Features

1. Easy driver specification using metaprogramming.
2. Fast multiprocessing pipeline for digitizer (or other) data.
3. Tight integration with QGL for quantum experiment definition.
4. Qubit calibration routines.
5. Run within Jupyter notebooks.
6. Easy pipeline specification and graphical display of pipelines.
7. Separate zmq/matplotlib plotting clients for local or remote use.
8. Custom high-performance file format (numpy mmaps) with full data axis descriptors and metadata.

Regrettably in-notebook plotting is difficult to implement for more than simple 1D sweeps. Notebook caching and javascript interface limitations make returning large amounts of data impractical. Final plots may be displayed
