Quantum Control Hardware Development for Semiconductor Spin Qubits

Semiconductor spin-qubits require precise mixed-signal circuits to control and readout quantum information. The growing demand for high-density/low-cost RF data converters, precision voltages sources, and low-noise hardware has led us to develop alternatives to off-the-shelf electronic instruments that interface with our spin qubits. Here we will discuss how platforms such as AMD’s ZYNQ RFSoC [1] and custom hardware development can be used to address future large-scale spin-qubit architectures. Specifically, circuit parameters necessary for cavity transmission, controlled spin rotations, potential biasing, and qubit state readout have all been considered and designed for in our approach.
