FPGA module synchronization for QubiC
ORAL
Abstract
As quantum bit (qubit) grows in count, the radio frequency (RF) control system becomes a limiting factor to large scale extensibility. To tackle this challenge and keep pace with rapidly evolving classical control requirements, we developed a synchronization protocol among multiple FPGA modules for distributed control systems. The pulse synchronization was presented on our customized FPGA-based RF control system (QubiC) with newly developed low-cost DAC boards. The synchronization functionality was demonstrated by two-qubit experiments on superconducting quantum information processors.
