A 8.5 GHz Quantum Analyzer by Zurich Instruments

The Swiss company Zurich Instruments has just introduced its SHFQA Quantum Analyzer that operates at up to 8.5 GHz and can thus perform direct readout of superconducting and spin qubits.

Conceived as the next generation of quantum computing instrumentation, the SHFQA combines signal generation at microwave frequencies with direct qubit readout and real-time multi-state discrimination.

With the SHFQA, reading out frequency-multiplexed qubits on up to 4 readout lines becomes a fast, high-fidelity operation that does not rely on tedious mixer calibration. As a single SHFQA can measure up to 64 qubits (or 32 qutrits or 20 ququads), it covers many functionalities that would otherwise require larger instrument racks and complex cabling arrangements.

As part of the Quantum Computing Control System (QCCS), the SHFQA is seamlessly integrated into new or existing setups featuring the HDAWG Arbitrary Waveform Generator and the PQSC Programmable Quantum System Controller. The LabOne user interface already known to Zurich Instruments’ customers gives access to an overview of all settings on the instrument, from the readout-band center frequency to the configuration of the low-latency analysis chain.
