Qudi: A modular python suite for experiment control and data processing

Abstract

Qudi is a general, modular, multi-operating system suite written in Python 3 for controlling laboratory experiments. It provides a structured environment by separating functionality into hardware abstraction, experiment logic and user interface layers. The core feature set comprises a graphical user interface, live data visualization, distributed execution over networks, rapid prototyping via Jupyter notebooks, configuration management, and data recording. Currently, the included modules are focused on confocal microscopy, quantum optics and quantum information experiments, but an expansion into other fields is possible and encouraged. Qudi is available from https://github.com/Ulm-IQO/ qudi and is freely useable under the GNU General Public Licence.

Clock transition by continuous dynamical decoupling of a three-level system

“…The experiments presented here were realised by the Qudi Software Suite [46]. We would like to thank Christian…”

Homoepitaxial Diamond Structures with Incorporated SiV Centers

“…The optical measurements were performed with a home built confocal microscope controlled by Qudi software suite . The excitation was achieved with a laser with a wavelength of 518 nm (Toptica iBeam smart), the fluorescence was detected through a 640 nm long pass filter by two Avalanche Photo Diodes (Excellitas) in a Hanbury Brown‐Twiss configuration for performing auto‐correlation measurements.…”
