The Zurich Instruments SHFPPC Parametric Pump Controller is a fully integrated system for operating Josephson parametric amplifiers. Leveraging the benefits of parametric amplification, the SHFPPC enables high-fidelity readout at the quantum limit for the measurement of superconducting or spin-based qubits.

Each channel features a microwave source with automatic level control to generate the required pump tone with high power and low phase noise. To suppress the residual pump tone in the return signal path, each channel features a cancellation circuit that can be calibrated automatically. The bi-directional operation of this circuit supports the two main application use cases: cancelling the pump tone at room temperature or in the cryostat.

SHFPPC Parametric Pump Controller
To achieve optimal readout fidelities, parametric amplifiers need to be operated at a point of large gain and maximal signal-to-noise ratio. The SHFPPC lets you find the optimal operation point quickly thanks to dedicated software routines and the ability to add independent pump and probe tones on one output port. This also enables regular performance monitoring and re-optimization without rewiring during a measurement session.

The SHFPPC is best operated in combination with one or more Zurich Instruments Quantum Analyzer channels - for example with the SHFQA Quantum Analyzer or the SHFQC Qubit Controller. The SHFPPC seamlessly integrates into a Quantum Computing Control System (QCCS) and can be controlled through the LabOne Python APIs, the LabOne QCCS Software, or the LabOne graphical user interface, enabling fast tune-up and stable operation during long experiment cycles.
