Quantum Mechanics (QM) is emerging from physics into non-physics domains (domains traditionally found outside of physics) such as human language, cognition, information processing, AI, biology, political science, economics, organizations, and social interaction. The Second Quantum Interaction Symposium advances and applies the methods and structures of QM to these and other non-physics domains, specifically including: . The advancement of theory and experimentation for applying QM to non-physics domains (including a clarification of what QM means in non-physics domains) . Applications of QM inspired methods to address, or to more efficiently solve, problems in non-physics domains (including contrasts between classical and quantum methods) . Applications of QM methods on a quantum computer, such as implementation of AI, or Information Retrieval (IR) techniques . Use of QM to address previously unsolved problems in other fields.
