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 SoftBank Corp. Publish Joint White Paper on Scaling Practical Quantum Computing Use Cases Toward the Fault-Tolerant Era
  • The companies have published a joint white paper mapping commercially relevant quantum computing use cases in quantum chemistry and graph analytics to Quantinuum’s hardware roadmap.
  • The paper provides a framework for assessing how advances in quantum hardware and algorithms could affect when practical industrial applications become feasible.
  • SoftBank Corp. and Quantinuum will use the roadmap to inform their exploration of future quantum AI data center services and related business models.

TOKYO and BROOMFIELD, Colo. – Quantinuum (NASDAQ: QNT) and SoftBank Corp. ("SoftBank") today announced the publication of “Quantum Computing Frontiers,” a joint white paper that maps two commercially-relevant quantum computing application areas against Quantinuum’s hardware roadmap. The analysis examines how advances in quantum hardware and algorithms could affect when these applications become practical for industrial use.

Building on this use-case roadmap, the paper also examines how quantum computing, AI, and high-performance computing could be integrated into future computing infrastructure. It considers how progress across successive hardware generations could inform future quantum AI data center services and related business models, a key focus of the Quantinuum and SoftBank partnership announced last year.

“The key takeaway of this study is that organizations do not need to wait for large-scale, fault-tolerant systems to explore where quantum computing can begin creating value,” said Duncan Jones, General Manager, Applications Group at Quantinuum. “By using today’s systems to develop, benchmark and refine applications in areas such as quantum chemistry and graph analytics, enterprises can build the technical and operational readiness needed for the next era of quantum-enabled computing.”

“The question is no longer whether quantum computing may deliver value, but rather which problem classes become executable at which stage of hardware maturity,” said Ryuji Wakikawa, Senior Vice President & CTO at SoftBank Corp. “However, we believe progress in hardware must be complemented by equally strong developments in quantum algorithms and the integration of quantum systems with AI and high-performance computing.”

The white paper discusses illustrative scenarios describing how representative applications, technology maturity, and potential market opportunities may evolve over time under stated assumptions. The analysis provided in the paper is intended to provide a conceptual framework for understanding potential market evolution and does not represent financial guidance or forecasts. These analyses are intended to support discussion of future technology development and should not be interpreted as commitments regarding commercialization, infrastructure investment, products, services, or financial performance.

The full white paper is available to download on the SoftBank and Quantinuum websites.
