The new SHFSG covers a complete frequency range from DC to 8.5 GHZ in a single box and succeeds the company’s previous two box solution that supported a more limited frequency range. It has been designed specifically for superconducting and spin qubits and takes advantage of the super-heterodyne frequency conversion technique to ensure better linearity and fewer spurious tones than with standard IQ-mixer-based methods. Cleaner control signals can potentially help the quantum gates achieve higher gate fidelities. Each SHFSG unit can provide up to 8 outputs and multiple units can be ganged together to provide synchronized control for quantum systems that have over 100 qubits. The unit can achieve a high level of integration with the upper levels of the quantum stack comes through Zurich Instrument’s LabOne instrument control software, driver compatibility with Labber and QCoDeS, and API support for Python, C/C++, MATLAB®, LabVIEW™ and .NET.
