LabRAD Guide

Introduction

LabRAD is an open source experimental control software developed by John Martinis group at UCSB. It was designed to be modular in order to scale well to deal with the complexity of modern quantum computing experiments. The software is broadly applicable beyond quantum computing efforts and is compatible with all major operating systems. You can read more about the LabRAD in the developer's introduction and a thesis describing the ideas. The developer's code in maintained in separate repositories for LabRAD manager, pylabrad sourceforge along with a guide for writing servers and clients in python, pylabrad git, LabRAD Modules and LabRAD for Delphi.
