Description

The Zurich Instruments SHFQA Quantum Analyzer integrates in a single instrument a full real-time readout setup for up to 64 superconducting and spin qubits. The SHFQA operates in a frequency range from 0.5 to 8.5 GHz with a clean analysis bandwidth of 1 GHz and without the need for mixer calibration. Each of its 2 or 4 readout channels can analyze up to 16 qubits, 8 qutrits or 5 ququads. For the 2-channel instrument, this performance requires the SHFQA-16W option.

The SHFQA enables multi-state discrimination with optimal signal-to-noise ratio and minimal latency thanks to its advanced sequencer and its low-latency signal processing chain with matched filters and result correlation. The data are transmitted in real time to other instruments for active qubit reset or global error correction protocols. Controlled through the LabOne software suite comprising the user interface, several APIs and the LabOne QCCS control software, the SHFQA supports quantum computing projects with sizes ranging from a few to several hundreds of qubits.
