The Zurich Instruments SHFSG Signal Generator produces qubit control signals in the frequency range from DC to 8.5 GHz with a spurious-free modulation bandwidth of 1 GHz. The SHFSG uses a double superheterodyne technique for frequency up-conversion, which eliminates the need for mixer calibration and saves time on system tune-up. Each SHFSG comes with 4 or 8 analog output channels with 14-bit vertical resolution. Controlled by LabOne, its APIs or the LabOne QCCS Software, the SHFSG supports quantum computing projects with sizes ranging from a few to several hundred qubits.
When synchronized by a PQSC, multiple SHFSGs can be combined within a Zurich Instruments QCCS to enable control of many-qubit systems. Multi-qubit gate operations with minimal latency and high fidelity can be realized thanks to an advanced sequencer, a low-latency signal processing chain and low-phase-noise synthesizers. Combined with the SHFQA Quantum Analyzer for real-time qubit readout, the SHFSG represents the second generation of instruments integrating microwave generation and analysis.
