QubiC: An open source FPGA-based control and measurement system for superconducting quantum information processors

Understand

As quantum information processors grow in quantum bit (qubit) count and functionality, the control and measurement system becomes a limiting factor to large scale extensibility.

• To tackle this challenge and keep pace with rapidly evolving classical control requirements, full control stack access is essential to system level optimization.
• We design a modular FPGA (field-programmable gate array) based system called QubiC to control and measure a superconducting quantum processing unit.
• The system includes room temperature electronics hardware, FPGA gateware, and engineering software.
