Zurich Instruments Launches its First Qubit Controller Offering a Full Qubit Control System in a Single Instrument


Zurich Instruments launches the SHFQC, its first qubit controller that can control, readout and perform fast feedback on up to 6 qubits. The SHFQC supports control and readout frequencies up to 8.5 GHz without the need for mixer calibration, and provides a wide and clean instantaneous bandwidth of 1 GHz.


The SHFQC comes with 6 signal generator control channels and a single quantum analyzer readout channel, each of which can be controlled and triggered individually. Internal data and trigger distribution allow for fast feedback and a flexible and software-controlled reconfiguration of the qubit control system. The control channels can be programmed to generate complex gate sequences using efficient pulse-level sequencing in their arbitrary waveform generators (AWGs). The readout channel analyzes up to 16 qubits, 8 qutrits, or 5 ququads in real-time – time-staggered or in parallel. Thanks to the matched complex filters and tight integration with the control channels, both signal-to-noise ratio and readout latency can be optimized. Turnkey features such as fast acquisition of a resonator spectrum, and a high level of integration through LabOne, the LabOne QCCS Software, or the APIs and drivers for Python simplify and accelerate system characterization and tune-up as well as algorithm execution.


The SHFQC integrates seamlessly into any new or existing Zurich Instruments Quantum Computing Control System and adds fast local feedback to existing error correction capabilities. Thus, a single SHFQC helps reduce the complexity of small qubit setups while also scaling up to systems of 100 qubits and beyond.
