The qudi-core repository represents the base installation for the qudi Python package.

It provides a versatile framework for modular multi-instrument and multi-computer measurement applications. It enables scientists and engineers to easily develop specialized multithreaded graphical or non-graphical applications.

Most of the more technical details about a complex measurement suite are handled automatically by qudi so the developer can focus on what matters most... the measurement control logic and the optional graphical user interface.

An incomplete list of functionality qudi provides:

• logging
• thread management
• automatic app status dumping/loading
• runtime resource management
• base modules for hardware interfaces, measurement logics and graphical user interfaces
• inter-module communication
• support for installable qudi namespace package addons
• interactive local IPython kernel interface
• high-level automation framework via tasks/scripts
• measurement setup configuration via YAML config file
• various tooling as a Python library
• basic data storage facility
• ...

If you are publishing any work based on using qudi as a framework/tool it is good practice to mention the qudi project, e.g. in the methods description.

Even better, you could simply cite our initial publication about qudi:
Qudi: A modular python suite for experiment control and data processing

The qudi contributors will appreciate this and it helps our open-source community to gain attention. This will hopefully attract more people willing to help in improving the qudi project which in turn benefits everyone using this software.

Thank you!
