Quantum Natural Language Processing

21 September 2020

Part of the Quantum Week of Fun



Due to the ongoing COVID-19 pandemic, and the uncertainty about travel and public gatherings, we have made the difficult decision to make QNLP20 a virtual event.

Full details about the arrangements will appear here nearer the time.


About the workshop

This workshop explores natural language processing (NLP) and its applications on quantum hardware, including today’s NISQ-era devices. Recent years have seen new compositional formalisms for NLP inspired by quantum theory and condensed matter physics, as well as fruitful research in quantum AI. These suggest that quantum computers provide a natural setting for NLP tasks, leading to the new field of Quantum NLP (QNLP).

Continuing from the previous edition QNLP 2019, this event aims to encourage the growth of this exciting topic, involving participants from both academia and the private sector working in quantum computing, artificial intelligence, machine learning, and linguistics.

The workshop will take place online and is part of Cambridge Quantum Computing's Quantum Week of Fun.
