The Zurich Instruments PQSC enables scalable quantum processor control through automated synchronization and low-latency communication between all components of a control system. It provides high-level software access to powerful real-time capabilities designed for the most pervasive use cases in quantum computing.
With 18 ZSync ports, the PQSC supports systems with up to 144 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.
Benefits
Proven system scalability
Up to 18 instruments can be synchronized through a PQSC, leading to coordinated readout and control of up to 100 fixed frequency qubits using only SHFQCs, or up to 60 tunable-frequency qubits. New instruments can be added by plugging one cable without rework of the existing system.
Simplified feedback programming
The QCCS comes with the LabOne Q software interface that lets users control feedback operations on the system level. LabOne Q translates a user’s high-level sequence into real-time instructions for all components of the QCCS so they can operate in sync, with the PQSC at the center. A Python API gives users the full flexibility to integrate the PQSC into their own software.
High-fidelity feedback operations
Due to the star topology of the QCCS architecture, the PQSC is able to evaluate the global state of all the qubits that it controls. This enables feedback methods that require global knowledge of the system state, such as Quantum Error Correction. The low-latency global feedback is complemented with local feedback operations inside the SHFQC Qubit Controller with further reduced latency.
Reliable synchronization
The ZSync interface distributes all clocks and timing signals needed to synchronize the system. Automated calibration procedures make the synchronization stable across reboots and changing environmental conditions. You can count on weeks of operation without the need for delay calibration.
QCCS instrumentation compatibility
The PQSC is compatible with two classes of QCCS system configurations:
- Combinations of HDAWG, SHFQC, SHFQA and SHFSG
- Combinations of HDAWG and UHFQA
