Summary:This demonstration shows a Quantum-Classical interface (QC-IF) for quantum computing implemented on multiple FPGAs. Quantum computers need a controller to transmit/receive microwave to/from quantum devices. In order to explore various quantum devices, the controller requires flexibility to transmit/receive various wave shapes. In addition to that, scalability is also required for large-scale quantum computers. FPGAs are attractive platforms; however, some challenges exist in implementing QC-IF on FPGAs in terms of required specifications from physics, such as treating data and realizing scalability. This work demonstrates an implementation of QC-IF on FPGA with high bandwidth memory to treat large-volume data in high throughput. Furthermore, the IEEE1588-like clock synchronization mechanism is implemented to make multiple FPGAs synchronized.
