PQSC#

The Zurich Instruments PQSC Programmable Quantum System Controller brings together the instrumentation required for quantum computers with up to 100 qubits. Its ZSync low-latency, real-time communication links are designed specifically for quantum computing: the PQSC overcomes the practical limitations of traditional control methods, making automated and rapid qubit calibration routines a reality. Programming access to the powerful Xilinx UltraScale+ FPGA is the basis for developing new and optimized processing solutions for rapid tune-up and error correction adapted to the specific algorithm and computer architecture in use.

Please refer to the user manual for an in-depth explanation of all features.

Like every device the device specific settings and data is organized in a path like structure called the node tree. zhinst-toolkit provides a pythonic way of interacting with this node tree. For more information about all functionalities and usage of the node tree in toolkit refer to the dedicated section.

zhinst-toolkit offers the following helper functions for the PQSC:

Helper Function	Info
`pqsc.arm()`	Prepare PQSC for triggering the instruments.
`pqsc.run()`	Start sending out triggers.
`pqsc.arm_and_run()`	Arm the PQSC and start sending out triggers.
`pqsc.stop()`	Stop the trigger generation.
`pqsc.wait_done()`	Wait until trigger generation and feedback processing is done.
`pqsc.check_ref_clock()`	Check if reference clock is locked successfully.
`pqsc.check_zsync_connection()`	Check if the ZSync connection on the given port is successful.
