The SHFSG: The First Signal Generator for Complete Qubit Control


Zurich Instruments has introduced the first signal generator, called SHFSG, designed specifically for superconducting and spin qubits.

The SHFSG Signal Generator can output signals from DC up to 8.5 GHz without having to spend time on mixer calibration, and it also offers a low noise and clean signal in 1 GHz bandwidth.


Leveraging the super-heterodyne frequency conversion method, the SHFSG Signal Generator delivers fewer spurious tones and better linearity when compared to regular IQ-mixer-based techniques.

The SHFSG Signal Generator can also be programmed to create complex pulse sequences. Consequently, this signal generator creates stable and clean signals without having to spend valuable time on system maintenance or mixer calibration.

The built-in synthesizers help boost the fidelity of qubit gate operations because of their low timing jitter and low phase noise across the whole output frequency range. The SHFSG Signal Generator comes in two versions—one with four channels and one with eight channels.

Excellent integration with the upper levels of the quantum stack is ensured by the LabOne software, API support for C/C++, Python, .NET, LabVIEW™ and MATLAB®, as well as driver compatibility with QCoDeS and Labber.

The SHFSG Signal Generator can be seamlessly integrated with all devices in the Quantum Computing Control System from Zurich Instruments so that it is ready to run error-correction protocols and rapid feedback.

A single SHFSG Signal Generator helps decrease the complexity of setting up small qubits; with a few synchronized instruments, users can scale up to 100 qubit systems and more.

Customers can learn more about the latest SHFSG Signal Generator from Zurich Instruments, including the entire list of its specifications at the company’s website.

Virtual Launch Event

Zurich Instruments will be holding a virtual launch event for the SHFSG on the 29th of April 2021. Join Zurich's event to learn how the SHFSG Signal Generator sets the standard for quantum computing. The event is composed of a technical overview, a practical demonstration, and an overall presentation of the instrument. Register for the webinar to learn how the SHFSG:

  • Operates at up to 8.5 GHz without requiring mixer calibration
  • Controls up to 8 qubits per instruments whilst maximizing gate fidelity
