How quantum mechanics can be related to information retrieval? In this year’s ECIR 2012, Dr. Benjamin Piwowarski and Dr. Massino Melucci gave a tutorial on Quantum Information Access and Retrieval.

It is still a little bit difficult to follow up the ideas introduced in the slides. However, it has been demonstrated in the tutorial that many aspects of IR are developed or re-phrased under QT framework, such as relevance theory, mixture of models, multiple document summarization and relevance feedback.

The current biggest initiative of QM is Quantum Interaction conferences.
