A Reconfigurable RFSoC Platform for High-Precision Control and Readout of Solid-State Qubits

Solid-state qubits have emerged as one of the leading candidates for the realization of scalable quantum computing architectures. However, achieving fault-tolerant utilityscale quantum computing remains a cross-cutting challenge that also depends on advances in enabling technologies such as scalable qubit control and readout systems.

We present a reconfigurable RFSoC-based platform for qubit control and readout and report an RF performance evaluation relevant to solid-state qubit measurements. The system is built on a modified version of the open-source Quantum Instrumentation Control Kit (QICK) [1] and integrates custom front-end modules to support operation across a wide frequency range. We characterize the phase noise performance of the platform and demonstrate synchronization between two independent control systems. These results highlight the potential of RFSoC-based solutions as scalable and flexible electronics for qubit quantum information processing.
