The Zurich Instruments QHub enables scalable quantum processor control through automated synchronization and low-latency communication between all components of a Quantum Computing Control System (QCCS). It provides high-level software access to powerful real-time capabilities designed for the most pervasive use cases in quantum computing.
With 56 ZSync ports, the QHub supports systems with up to 448 microwave channels for precisely timed and stable gate and readout operations. Central data processing enables feedback methods that require global information of the system state, e.g. for quantum error correction, with a latency down to 550 ns including all signal processing.
Decoding algorithms can be efficiently implemented on a powerful FPGA core using a ready processing infrastructure accessible in Python. Optional direct programming of the FPGA provides the flexibility required in developing novel decoder algorithms.
