The international quantum interaction (QI) symposium series provides a unique cross-disciplinary forum for researchers. Quantum Interaction (QI) is an emerging field which is applying quantum theory (QT) to domains such as economics, organisations and social interaction, psychology, artificial intelligence, human language, cognition, information retrieval, biology, political science. The application areas addressed typically operate at a macroscopic scale and could not be considered quantum in a quantum mechanical sense, they may share many key properties with quantum systems including:

Non-commutativity of measurement, Indeterminacy, Non-separability, Contextuality, Harmonic oscillations.
