Integrated Qubit Control System

ZHI SHFQC01 December 2021 - Zurich Instruments launched the SHFQC Qubit Controller, which offers a full room-temperature qubit control system for up to 6 superconducting qubits in a single instrument. The SHFQC provides channels for driving high-fidelity single- or two-qubit gates, perform single-shot multiplexed qubit readout, and perform fast feedback or error correction protocols. When using several SHFQCs, the control system can be extended to support larger qubit numbers and thus adds fast local feedback to global error correction.

Like other elements of the Zurich Instruments Quantum Computing Control System (QCCS), the channels of the SHFQC work at microwave frequencies with great spectral purity and stability, thus avoiding the need for mixer calibration. As part of the QCCS, the SHFQC can be integrated into new or existing setups consisting of up to 18 other instruments such as the HDAWG Arbitrary Waveform Generator, the SHFSG Signal Generator and the PQSC Programmable Quantum System Controller to scale from few qubits to 100 qubits and beyond. The LabOne software, the new LabOne QCCS Software and the LabOne Python APIs help users handle any combination of QCCS instruments as one system that remains well-synchronized and controlled by a single software interface.
