Cambridge Quantum Computing Performs the World’s First Quantum Natural Language Processing Experiment

By IQT News posted 07 Apr 2020

(PRNewswire) Cambridge Quantum Computing (“CQC”) announces that they have used the “natively quantum” structure of natural language to open up an entirely new realm of possible applications by translating grammatical sentences into quantum circuits, and then implementing the resulting programs on a quantum computer and actually performing question-answering. This is the first time that natural language processing has been executed on a quantum computer. Furthermore, by achieving the results without relying on quantum RAM, CQC scientists have created a path to truly applicable quantum advantage within the Noisy Intermediate-Scale Quantum (“NISQ”) era.
By using CQC’s class-leading and platform-agnostic retargetable compiler t|ket⟩™, these programs were successfully executed on an IBM quantum computer, thus taking a notable step towards achieving “meaning-aware” and “grammatically informed” natural language processing – a dream of computer scientists since the earliest days of the computer age. CQC looks forward to providing further details in the near future including ways to scale the programs so that meaningfully large numbers of sentences can be used on NISQ machines as they themselves scale in quantum volume and using other types of quantum computers.
