Coordinating Decisions via Quantum Telepathy
Dawei Ding, Liang Jiang

TL;DR
This paper explores how quantum entanglement and Bell inequality violations can be used to enable decision coordination in scenarios where communication is limited, such as high-frequency trading, demonstrating near-term practical quantum advantages.
Contribution
It introduces a conceptual framework applying quantum telepathy to real-world decision-making problems and evaluates physical implementations for achieving quantum advantage in high-frequency trading.
Findings
Quantum telepathy can be practically realized with current technology.
Bell inequality violations provide a provable quantum advantage without complex assumptions.
Single-qubit operations on entangled qubits suffice for demonstrating quantum advantage.
Abstract
Quantum telepathy is the phenomenon where two non-communicating parties can exhibit correlated behaviors that are impossible to achieve using classical resources. This is also known as Bell inequality violation and is made possible by quantum entanglement. In this work, we present a conceptual framework for applying quantum telepathy to real-world problems. In general, the problems involve multiple parties making local observations that need to coordinate their decisions but are unable to communicate. We argue this inability is actually quite prevalent in the modern era where the decision-making timescales of computer processors are so short that the speed of light delay is appreciable in comparison. We highlight the example of high-frequency trading (HFT), where trades are made at microsecond timescales, but the speed of light delay between different stock exchanges are on the order of…
