\begin{block}{Abstract}
Experiments in quantum optics often require a large number of control loops, e.g.\ for length-stabilization of optical cavities and control of phase gates. These control loops are generally implemented using one of three approaches: commercial (digital) controllers, self-built analog circuitry, or custom solutions around ``maker-style'' projects based on FPGAs and microcontrollers. Each of these approaches has individual drawbacks, such as high cost, lack of scalability and flexibility, or high maintenance effort. Here we present a solution based on the ADwin digital control platform that is able to deliver in excess of \simulchans\ simultaneous locking loops running with \samplefreq\ sampling frequency, and offers five second-order filtering sections per channel for optimal control performance. A comprehensive software package written in Python, together with a web-based GUI, makes the system as easy to use as commercial products, while giving the full flexibility of open-source platforms.

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Control loops are a fundamental part of many experiments in quantum optics. They are used to precisely control (``lock'') the interference of laser beams, keep optical cavities on resonance, stabilize lasers to atomic transitions, and much more. Depending on the subject area, a clustering of different hardware implementations for these control loops can be observed, with designs and approaches shared when researchers move between groups. Some groups -- including ours until recently -- solely rely on self-built analog electronics. Others have successfully implemented control loops with micro-controllers \cite{huang_microcontroller-based_2014} or FPGA boards \cite{neuhaus_pyrpl_2017}. Working groups close to large collaborations, e.g.\ particle physics or gravitational-wave astronomy, tend to use the purpose-built control and data acquisition systems of these fields \cite{epics,desy_doocs_nodate,bork_advligo_nodate}. Commercial solutions are also available and are successfully used in some applications.
