Quantum Delocalised-Interactions

Classical physics obeys the intuitive logic that if something happened then it happened somewhere, it just might be unknown where. Entanglement breaks this, enabling interactions without a single specific location. In this work we study these delocalised-interactions, whereby an interaction happens whilst creating less locational information than would be classically possible. We introduce quantum games to capture the effect and prove bounds that demonstrate a direct operational use for quantum concurrence. We also find a connection with quantum teleportation, explore an information theoretic approach, and demonstrate the games using an IBM quantum processor.
