QUAlibrate, an open-source framework for quantum computer calibration, was released by Quantum Machines, the industry leader in sophisticated hybrid quantum-classical control solutions. In addition to offering a complete solution for developing, implementing, and exchanging calibration protocols across various quantum computing platforms, the framework significantly reduces calibration timeframes. QUAlibrate speeds up the development of useful quantum computers by fostering an open ecosystem that allows scientists and businesses around the world to build on each other’s work.
Overview of QUAlibrate
An automated calibration program called QUAlibrate was created to streamline and expedite the difficult process of quantum calibration, greatly increasing user productivity. Because of its scalability, it can parallelize multi-qubit tune-up and complete qubit tune-up in less than a minute.
The adaptable graph-based methodology of QUAlibrate is one of its main features. The workflow and logic are established by calibration graphs, which are composed of nodes that reflect particular activities such as spectroscopic or gate tuning. These nodes are implemented as QUA programs, which can be chosen from QUAlibrate’s extensive library or created from scratch. These graphs can be intelligently navigated and optimized to sophisticated traversal techniques. These nodes and graphs can be programmed and customized at the code level to the software.

QUAlibrate uses the component-based Quantum Abstract Machine (QUAM) based on the QUA programming language. Flexible, hardware-agnostic calibration methods are made possible by QUAM’s creation of a digital representation of the quantum system, including its qubits and hardware. Without requiring hardware-specific code, this streamlines setup, improves control, and guarantees consistency, freeing users to concentrate on qubit operations.
For complete visibility and control, the software offers an easy-to-use web-based interface. Users can interactively alter settings based on real-time results, run calibration algorithms, and view outcomes using real-time visualizations and charts in the Calibration Node. Users can parallelize calibration across qubits, select traversal methods, create automatic graphs, and monitor progress with real-time updates in the Calibration Graph View.
QUAlibrate is designed to work with OPX hybrid controllers, such as the NVIDIA DGX Quantum, OPX+, and OPX1000. Additionally, it is completely open source under BSD-3 licensing, with the goal of promoting cooperation and offering control and clarity.
QUAlibrate significantly increases productivity by streamlining the difficult process of quantum calibration. With a full qubit tune-up in less than a minute, it allows parallelized multi-qubit tune-up and is built for scale. Users can program and change calibration graphs and nodes at the code level using QUAlibrate.
For today’s and tomorrow’s quantum systems, QUAlibrate guarantees high-fidelity calibration and smooth scalability through interactive execution, live visualisation, and strong data management.
Customizable Calibration Graphs
QUAlibrate’s graph-based methodology is its fundamental component: The control flow logic of calibration graphs can be fully customised. They consist of nodes, each of which stands for a particular activity, such as gate tuning, Rabi experiments, or spectroscopy.
- Nodes are implemented as QUA programs, which can be either custom-built or chosen from the extensive library of pre-built control applications available in QUAlibrate.
- Calibration graphs operate concurrently on any number of chosen qubits and establish the connections and interactions between nodes depending on qubit-specific outcomes.
- Intelligent traversal and graph optimization are made possible by sophisticated traversal algorithms.
Quantum Abstract Machine (QUAM)
QUAlibrate uses QUAM, a component-based architecture built on top of the QUA programming language. With QUAM, your entire quantum system from qubits to hardware is digitally modelled, allowing for more adaptable, hardware-independent calibration processes. It guarantees uniformity among devices and experiments, improves control, and streamlines setup.
- Avoid using code that is specific to hardware and concentrate on qubit operations.
- Reduce the overhead of adjusting to new systems.
- Calibration procedures can be easily logged and rerun.
Intuitive Web Interface
Through its web-based interface, QUAlibrate offers total visibility and control over calibration processes, from the execution of individual nodes to full graph orchestration.
Calibration Node View
- Use the built-in application library to run calibration procedures or write your own QUA-based algorithms.
- Plots and comprehensive, real-time visualisations of the results are displayed.
