Zurich Instruments introduces a new generation of signal generators for quantum computing

Posted 31 marzo 2021

The SHFSG Signal Generator is an instrument designed to control superconducting and spin qubits and reach higher fidelities with less overhead time.

As the first solution of its kind on the market, the SHFSG operates directly at qubit frequencies without mixer calibration. The SHFSG sets new standards in spectral purity and stability, and ensures that the highest possible gate fidelity is achieved and maintained during operation. As an integral component of the Zurich Instruments Quantum Computing Control System, the SHFSG provides a scalable solution for controlling quantum processors.

The SHFSG generates freely programmable pulse sequences on up to 8 outputs with a signal bandwidth of 1 GHz and a variable carrier frequency up to 8.5 GHz. Such microwave signals are required to control the state of qubits in quantum computers, and they previously had to be generated using a combination of arbitrary waveform generators, microwave signal generators, and mixer circuits. The SHFSG brings together all these instruments in a single box, and it eliminates the need for time-consuming and error-prone calibration routines.

As part of the Quantum Computing Control System (QCCS), the SHFSG is seamlessly integrated into setups featuring the HDAWG Arbitrary Waveform Generator and the SHFQA Quantum Analyzer.

The LabOne QCCS Software allows users to define multi-channel signals involving all instruments in the setup in the form of a pulse-level description abstracted from the hardware. The LabOne user interface, already known to Zurich Instruments’ customers, gives access to an overview of all hardware settings and to the instrument-level sequence description.
