Abstract:
Quantum computers rely on classical computers for control and readout. In the NISQ era, quantum computers are increasing in scale and spanning a broader range of QPU architectures and experiment/algorithm design, requiring cost-effective and flexible control systems. QubiC, the open-source control system developed at Lawrence Berkeley National Laboratory, was designed to support quantum computers in this evolution. After a few developmental years, QubiC 1.0 demonstrated its control and measurement capabilities on a superconducting quantum processing unit (QPU). With growing requirements from the QPU, QubiC 2.0 was developed on the latest RFSoC platform with mid-circuit measurement and feed-forward features, along with a new AC analog front-end. The latest updates focus on performance — with hardware-efficient randomized compiling (RC) and hardware-assisted parameterized circuit execution —, scalability — with software capable of synchronizing multiple boards —, and supporting a broader range of superconducting QPUs with an AC and DC-coupled analog front-end.
