Abstract: Quantum telepathy is the concept of using quantum entanglement to solve real-world problems that require decision coordination between parties among which communication between certain pairs is restricted. One possible reason for this communication restriction is a latency constraint: some pairs of parties do not have sufficient time to exchange information before producing their outputs. Example scenarios include high-frequency trading and distributed systems. Another reason is physical or operational isolation: for certain pairs of parties, communication is obstructed. Example scenarios include drone navigation in remote areas and ad hoc network routing where nodes belong to competing firms. This paper provides a concise overview of the diverse application areas of quantum telepathy. These realworld problems can be modeled as nonlocal games or their generalizations, in which a subset of parties may communicate. In addition, possible physical implementations are also discussed. Quantum telepathy offers a provable quantum advantage, as guaranteed by Bell's theorem, and this advantage can be realized using existing quantum hardware.
