Y66.00001: Qblox & Quantify: fully integrated control hardware and open-source software for a variety of scalable quantum computers Cornelis Christiaan Bultink, Jules C. van Oven, Marijn Tiggelman In the race towards creating quantum computers with real-life applications, major challenges have to be overcome: improving the quality of qubits and gates, harnessing algorithms with error mitigation, and implementing fast and automated calibration procedures. Crucial to this end is the control hardware and software that orchestrate quantum experiments. Meet the Qblox control hardware: commercially available, massively scalable control systems that generate and interpret signals in the range from DC to >18 GHz. By giving our sequencers real-time access to pulse amplitudes, offsets and modulation phases, it allows bypassing slow communication with the user pc. The Qblox hardware can be conveniently operated with Quantify: a robust and extensively documented open-source software platform. Quantify contains all the basic functionality to control experiments (e.g., instrument management, live plotting, data storage, etc.), as well as a novel scheduler featuring a unique hybrid control model allowing quantum gate- and pulse-level descriptions to be combined in a hardware-agnostic way. This creates a massively scalable control stack with tight integration of all hardware and software components applicable to a variety of quantum systems. |
