Quantinuum Announces Updates to Quantum Natural Language Processing Toolkit λambeq, Enhancing Accessibility
λambeq update introduces many new important features to provide researchers and developers with more options and flexibility in turning sentences into quantum circuits
Oxford, United Kingdom, March 29th, 2022 — The quantum natural language processing team at Quantinuum, the world’s leading integrated quantum computing company, has released a major update to its open-source Python library and toolkit, λambeq (pronounced “Lambek”).
λambeq converts any natural language sentence into a quantum circuit, ready to be realized on a quantum computer. The new release has been designed for a growing community of researchers, developers and users versed in quantum natural language processing (QNLP) and natural language processing (NLP). Natural language processing markets are projected to grow 27% annually over the next five years.
The update will support the growth of QNLP and potential future applications such as automated dialogue, text mining, language translation, text-to-speech, language generation and bioinformatics.
Quantinuum’s Head of Applied Quantum NLP Research, Dr. Dimitrios Kartsaklis, said: “Since we launched λambeq, we have received valuable feedback from a rapidly growing community of users, and many of the new features available today reflect this. The new version of λambeq now comes, for example, with a native state-of-the-art parser that has been fully integrated with the toolkit. Additionally, the toolkit is now equipped with a training package that supports popular supervised learning libraries, such as PyTorch, to help users efficiently train NLP tasks using the quantum circuits and tensor networks that λambeq generates. This update is all about accessibility – and crucially, reducing the time it takes to achieve results.”
Additionally, and importantly, λambeq’s new neural-based CCG parser, Bobcat, is trained on a large human-annotated corpus of syntactic derivations. It is fully integrated with the toolkit, simplifying the installation process, and presents improved state-of-the-art parsing performance. The previous parser remains part of the toolkit, and for the benefit of the community, Bobcat will also be released as a separate stand-alone open-source tool in due course.
The new update is equipped with a command-line interface, making most of the toolkit's functionality available to users with no programming knowledge. It also contains a new supervised training module designed to simplify the process of training parameterized quantum circuits and tensor networks in a machine learning setup.
λambeq is the first quantum NLP and computational linguistics toolkit. It can convert a sentence into a quantum circuit that inherits its entanglement structure from the sentence's syntactic structure. This construction is motivated by formal mathematical correspondences between mathematical models of grammar and quantum protocols, as established by senior researchers at Quantinuum, Chief Scientist Prof. Bob Coecke and Head of AI Prof. Stephen Clark.
With this update, λambeq becomes more flexible in providing users with more options on the quantum circuits it can generate. It allows manipulation of syntax diagrams and makes it simpler to define the quantum circuits from the syntactic structure.
The visualization of λambeq's output has also been improved, and documentation has been expanded with numerous examples to remove the barrier to entry for general users.

- Strategic collaboration aims to establish framework for combining quantum computing with HPC and AI environments
- The collaboration will engage enterprise customers seeking hybrid quantum-classical solutions across high-value scientific and industrial use cases
Broomfield, CO and Houston, TX, June 22nd, 2026 — Quantinuum (NASDAQ:QNT), a leading quantum computing company, today announced a strategic collaboration with HPE focused on integrating quantum computing with high-performance computing (HPC) and AI infrastructure.
“We envision a future where quantum computers work seamlessly with classical computers to unlock scientific discovery and practical, real-world value for industries,” said Dr. Rajeeb Hazra, President and CEO of Quantinuum. “As a leader in trapped-ion quantum computing, we look forward to integrating our high-fidelity systems with leading classical architectures. This collaboration with HPE represents an important step in our broader ecosystem approach to delivering practical, hybrid solutions to our enterprise, public sector, and research customers.”
The strategic collaboration is intended to develop quantum computing technologies that become a practical extension of a customer’s HPC and AI strategy. Together, the companies will explore hybrid reference architectures, validate application workflows, and engage with select customers on approaches that combine quantum technology with large-scale classical environments.
“Accelerating scientific and industrial discovery requires a deeply integrated, hybrid approach that brings together the best of classical supercomputing, AI, and quantum technology,” said Masoud Mohseni, Director of HPE Quantum and Senior Distinguished Technologist at HPE Labs. “Through this collaboration with Quantinuum we will be integrating our systems toward a scalable infrastructure for classical-quantum applications.”
