Clock Synchronization and Data Exchange between FPGA Modules for Superconducting Qubit Control

ORAL

Abstract

Controlling systems for multiple qubit operation can easily exceed the capability of a single FPGA chip. Synchronization among multiple FPGA-based modules is essential for resource-efficient system scale up. We propose and develop a fiber-based clock synchronization and data exchange protocol for inter-module communication using our in-house developed FPGA based RF control system - QubiC. The preliminary test results on this prototype system are presented.
