Quantum Natural Language Processing, often abbreviated as QNLP, is a natural language processing technique[1] created by Bob Coecke, Mehrnoosh Sadrzadeh, and Stephen Clark. This idea is explained in the following video:Q2B 2020-Quantum Natural Language Processing[2].

There is also a Youtube channel dedicated to QNLP.

The CQM Insight

In the video[3], Bob stated there are two aspects of languages:

  1. Structure of the Sentence(Grammar Algebra)[4]
  2. Meaning of Words(Vector Space NLP)

The insight is that Bob Coecke combined/composed the two mechanisms using Categorical Quantum Mechanics/(CQM).
