Introducing the Next Version of λambeq

A leading open-source software development tool for Quantum Natural Language Processing (“QNLP”) debuts integration with PennyLane, an Enhanced Training Package, and Support for Quantum Specialists new to NLP

April 12, 2023

The quantum natural language processing team at Quantinuum, the world’s largest, standalone quantum computing company, is excited to announce a major update to its open-source Python library and toolkit, λambeq (pronounced "Lambek"), to version 0.3.0. 

This update brings several enhancements that not only improve the user experience but significantly expand the capabilities the toolkit provides to its rapidly growing user community, including a growing number of quantum developers and engineers considering natural language processing (NLP) and machine learning (ML) for the first time.

The most significant parts of today’s announcement are: 

  • the introduction of PennyLane integration;
  • an improved model training package; and
  • new tutorials to introduce quantum professionals to technical NLP and ML
Unlocking New Possibilities with PennyLane Integration

A notable feature of this update is the integration of PennyLane, a powerful quantum computing library that is widely used by engineers and developers all over the world. With PennyLane support, users of λambeq can now develop hybrid quantum-classical models using the PennyLaneModel, hooking numerically determined gradients of parameterized quantum circuits (PQCs) to modules of ML libraries like PyTorch. This integration unlocks new possibilities for researchers and developers working on quantum natural language processing.

Enhanced Training Package for a Streamlined Experience

This update also brings significant improvements to the training package, with the addition of new λambeq-native loss functions that will help users more easily to train their models using standard implementations, oriented to classification tasks and others such as regression. This streamlined experience allows users to focus on their research and development without the need for custom loss functions. It not only enables better training performance on larger models but is also part of the team’s effort to make λambeq fully ML-enabled.

Helping Quantum Computing Engineers Explore NLP and ML

Another feature in this release is new NLP-101 tutorial support. This was developed following feedback from users, who are turning their attention to quantum NLP and quantum ML with increasing frequency. Many new λambeq users do not have a deep knowledge of techniques such as text pre-processing or the best practices required to perform successful experiments.

A technical tutorial has been published in notebook form, to help developers and engineers working in QML or QNLP to explore what is possible using λambeq.

Additional Features and Enhancements

In addition to the major features highlighted above, this update includes several other enhancements and bug fixes:

  • Support for Python 3.11
  • Improved fail-safety in the BobcatParser model download method
  • Fixed various bugs, including issues with the SPSAOptimizer and NumpyModel tests
  • Enhanced exception handling and documentation requirements
QNLP in the community

The launch of λambeq 0.3.0 update is a natural step for Quantinuum, which is not only the world’s largest standalone quantum computing company, but also the pioneer and leader in QNLP, in supporting the growth of quantum natural language processing and its applications. By continually enhancing the toolkit and providing cutting-edge integrations and resources, Quantinuum is paving the way for researchers, developers, and users in the ever-growing QNLP and NLP communities. QNLP offers us a way to take full advantage of the possibilities of advancing the boundaries of AI and truly using the promise that has been exhibited in part by Large Language Models such as GPT-4 whilst continuing to work to solve some of the well documented short-comings of such classical technologies.

Quantinuum and BMW Group Expand Landmark Quantum Computing Collaboration with New Multi-Year Partnership
  • The companies plan to continue their co-creation partnership to advance future mobility
  • BMW to access the latest generations of Quantinuum systems throughout the partnership
  • Advanced materials science research supports a range of next-generation technologies

Broomfield, Colorado, May 5th, 2026 — Quantinuum and BMW Group have formally expanded their ongoing collaboration into a multi-year partnership with a mission to unlock future mobility by applying quantum computing toward advanced materials science.

Since 2021, Quantinuum and BMW Group have been collaborating on joint research focused on tackling complex challenges in industrial chemistry to support the advancement of next-generation mobility. The collaboration has progressed from foundational algorithm development to advanced simulations of molecular systems, allowing the researchers to unlock insights into catalytic activity, reaction pathways, and material performance in energy-relevant environments.

The companies have now agreed to extend the work, positioning the alliance to become one of the longest-sustained commitments between a commercial enterprise and a quantum computing provider to date.

“Quantinuum is focused on driving commercial adoption of quantum computing through close collaboration with industry leaders on high-impact applications," said Dr. Rajeeb Hazra, President and CEO of Quantinuum. “Our expanded partnership with the BMW Group underscores this focus, and we’re excited to scale the meaningful work we’ve been advancing together.”

Researchers at BMW Group are utilizing Quantinuum's trapped-ion architecture, which provides the high-fidelity operations necessary to accurately simulate molecular systems, particularly electrochemical processes that play a critical role across a range of technologies relevant to sustainable mobility and the design and optimization of fuel cells.

Under the terms of the agreement, BMW Group will leverage successive generations of Quantinuum’s quantum computers. This includes the current Helios system and upcoming generations, Sol (planned for 2027) and Apollo (planned for 2029). This will enable the teams to validate progress at each stage while scaling toward industrially meaningful solutions.

“We have been exploring quantum computing for many years,” said Dr. Martin Tietze, Vice President of New Technologies at BMW Group. “Together with partners such as Quantinuum, we translate advances in quantum hardware into real‑world applications, including materials optimization, supporting the development of future vehicle generations.”

Quantinuum’s progress toward large-scale, fault-tolerant systems helps to ensure that as the hardware reaches milestones in performance, BMW can apply that computational power to catalyst chemistry research, targeting critical oxygen reduction reaction processes at platinum catalysts to potentially lower costs and improve energy efficiency.

The companies broke new ground in 2024, alongside another commercial partner, as the first to simulate catalytic performance using a quantum computer with results published in Nature Partner Journal.

Beyond its technical achievements, the collaboration has evolved into a deeply connected, cross-disciplinary effort, bringing together quantum scientists, chemists, and engineers in a sustained partnership that reflects both the complexity of the challenge and the scale of the ambition.
