Summary:Quantum control processors (QCPs) bridge the gap between the quantum software and the hardware backend to construct full-stack quantum computers. In this study, the quantum backend interface is responsible for generating pulses to control qubits, where commercial waveform generators or specific converters are typically needed. A radio frequency system-on-chip (RFSoC)-based QCP supports a direct control pulse synthesis without additional components. Therefore, in this work, we propose an RFSoC-based QCP that integrates the processor and pulse generation logic onto a single board. With the help of the proposed instruction set and efficient microarchitecture implementation, the QCP offers large scalability for controllable qubits, while supporting different physical platforms.
