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.

Broomfield, CO, April 3rd, 2025 — Quantinuum, the industry leader in quantum computing with the world’s most powerful quantum computer, has been selected by the Defense Advanced Research Projects Agency (DARPA), a research and development agency of the United States Department of Defense, to participate in the first stage of the agency’s Quantum Benchmarking Initiative (QBI).
QBI aims to assess the feasibility of building an industrially useful quantum computer by 2033. Successful QBI performers will advance through stages A, B, and C; Stage A requires performers to describe their utility-scale quantum computer with a path to near-term realization, where utility-scale means the computational value exceeds costs.
As validated in a recent independent benchmarking study by a group of institutions at the forefront of quantum computing research, Quantinuum’s quantum systems are the highest performing in the industry. Last year, Quantinuum published its development roadmap, outlining a path to a universal, fully-fault tolerant quantum computer by 2029. Beyond this public roadmap, Quantinuum plans to scale to even larger machines in the early part of the 2030s, aligning with the objectives of QBI.
“We are honored to collaborate with DARPA and look forward to working closely with their test and evaluation team as they assess our roadmap and technological approach,” said Dr. Rajeeb Hazra, President and CEO of Quantinuum. “With our roadmap firmly on track, we are confident in our ability to deliver on DARPA’s objectives for QBI.”
Microsoft and NVIDIA will take part in Quantinuum’s Stage A effort, building on their long-standing collaborations with Quantinuum in advancing commercially scalable quantum computing.
