Qudi is a suite of tools for operating multi-instrument and multi-computer laboratory experiments. Originally built around a confocal fluorescence microscope experiments, it has grown to be a generally applicaple framework for controlling experiments.

• A modular and extendable architecture
• Access to devices on other computers over network
• XYZ piezo or galvo control for confocal fluorescence microscopy via National Instruments X-Series devices
• Position optimization for fluorescent spots
• Tracking of fluorescent spots
• Tektronix AWG 5000 7000 and 70000 support for pulsed microwave experiments
• Anritsu MG37022A, MG3696B and MG3961C, R&S SMIQ and SMR support for ODMR measurements
• Getting spectra from the WinSpec32 spectroscopy software
• Thorlabs APT motor control
• Magnetic field alignment for NV- in diamond via fluorescence, ODMR and nuclear spin
• etc.

If you are publishing scientific results, mentioning Qudi in your methods decscription is the least you can do as good scientific practice. You should cite our paper Qudi: A modular python suite for experiment control and data processing for this purpose.

User and code documentation about Qudi is located at http://ulm-iqo.github.io/qudi-generated-docs/html-docs/ .

For development-related questions and discussion, please use the qudi-dev mailing list.

If you just want updates about releases and breaking changes to Qudi without discussion or issue reports, subscribe to the qudi-announce mailing list.

Feel free to add issues and pull requests for improvements on github at https://github.com/Ulm-IQO/qudi .

The code in pull requests should be clean, PEP8-compliant and commented, as with every academic institution in Germany, our resources in the area of software development are quite limited.

Do not expect help, debugging efforts or other support.
