Introduction
The Quantum NLP project in the NLP Lab is currently a study group focusing on the most recent papers in Quantum NLP. Our goal is to familiarize everybody with the different tools and environments for QNLP and work on interesting questions related to Quantum and language-related computation or cognitive aspects of language processing and quantum models.
The study group meets independently of the NLP Lab weekly meeting at IU-B. If you want to join this meeting, contact Damir Cavar directly.
