Cambridge Quantum Computing (CQC) hiring Stephen Clark as head of AI final week may very well be an indication the corporate is boosting analysis into methods quantum computing may very well be used for pure language processing.

Quantum computing continues to be in its infancy however guarantees such important outcomes that dozens of firms are pursuing new quantum architectures. Researchers at expertise giants reminiscent of IBM, Google, and Honeywell are making measured progress on demonstrating quantum supremacy for narrowly outlined issues. Quantum computer systems with 50-100 qubits could possibly carry out duties that surpass the capabilities of at this time’s classical digital computer systems, “however noise in quantum gates will restrict the dimensions of quantum circuits that may be executed reliably,” California Institute of Expertise theoretical physics professor John Preskill wrote in a latest paper. “We could really feel assured that quantum expertise could have a considerable influence on society within the many years forward, however we can’t be almost so assured concerning the industrial potential of quantum expertise within the close to time period, say the following 5 to 10 years.”

CQC has been promoting software program centered on particular use circumstances, reminiscent of in cybersecurity and pharmaceutical and drug supply, because the {hardware} turns into accessible. “We’re very totally different from the opposite quantum software program firms that we’re conscious of, that are primarily centered on consulting-based revenues,” CQC CEO Ilyas Khan informed VentureBeat.

For instance, amid issues that enhancements in quantum {hardware} will make it simpler to interrupt current algorithms utilized in fashionable cryptography, CQC devised a technique to generate quantum-resistant cryptographic keys that can not be cracked by at this time’s strategies. CQC companions with pharmaceutical and drug discovery firms to develop quantum algorithms for bettering materials discovery, reminiscent of working with Roche on drug improvement, Whole on new supplies for carbon seize and storage options, and CrownBio for novel most cancers therapy biomarker discovery.

Transferring into AI

The addition of Clark to CQC’s crew indicators the corporate might be shifting a few of its analysis and improvement efforts towards quantum pure language processing (QNLP). People are good at composing meanings, however this course of isn’t properly understood. Latest analysis established that quantum computer systems, even with their present limitations, might study to cause with the uncertainty that’s a part of real-world situations.

“We have no idea how we compose which means, and due to this fact we now have not been certain how this course of will be carried over to machines/computer systems,” Khan mentioned.

QNLP might allow grammar-aware illustration of language that is smart of textual content at a deeper stage than is at the moment accessible with state-of-the-art NLP algorithms like Bert and GPT 3.0. The corporate has already demonstrated some early success in representing and processing textual content utilizing quantum computer systems, suggesting that QNLP is inside attain.

Clark was beforehand senior employees analysis scientist at DeepMind and led a crew engaged on grounded language studying in digital environments. He has an extended historical past with CQC chief scientist Bob Coecke, with whom he collaborated 15 years in the past to plan a novel strategy for processing language. That analysis stalled because of the limitations of classical computer systems. Quantum computing might assist handle these bottlenecks, and there are plans to proceed that analysis program, Clark mentioned in an announcement.

“The strategies we developed to reveal this might enhance a broad vary of purposes the place reasoning in complicated programs and quantifying uncertainty are essential, together with medical diagnoses, fault-detection in mission-critical machines, and monetary forecasting for funding administration,” Khan mentioned.
