This study demonstrates that quantum advantages in strategic coordination can survive on current noisy hardware by using dynamic circuit mapping to mitigate decoherence and routing errors. The experimental results validate theoretical predictions for the Battle of the Sexes game, showing consistent payoff trends despite NISQ limitations. This work provides a concrete pathway toward practical applications of quantum game theory in multi-agent systems and distributed decision-making.
Bridging Theory and Practice in Quantum Game Theory: Optimized Implementation of the Battle of the Sexes with Error Mitigation on NISQ Hardware
arXiv:2508.09050v3 Announce Type: replace Abstract: Implementing quantum game theory on real hardware is challenging due to noise, decoherence, and limited qubit connectivity, yet such demonstrations are essential to validate theoretical predictions. We present one of the first full experimental realizations of the Battle of the Sexes game under the Eisert-Wilkens-Lewenstein (EWL) framework on IBM Quantum's ibm sherbrooke superconducting processor. Four quantum strategies (I, H, $R(\pi/4)$, $R(\pi)$) were evaluated across 31 entanglement values $\gamma \in [0, \pi]$ using 2048 shots per configuration, enabling a direct comparison between analytical predictions and hardware execution. To mitigate noise and variability, we introduce a Guided Circuit Mapping (GCM) method that dynamically selects qubit pairs and optimizes routing based on real-time topology and calibration data. The analytical model forecasts up to $108\%$ payoff improvement over the classical equilibrium, and despite hardware-induced deviations, experimental results with GCM preserve the expected payoff trends within $3.5\%$-$12\%$ relative error. These findings show that quantum advantages in strategic coordination can persist under realistic NISQ conditions, providing a pathway toward practical applications of quantum game theory in multi-agent, economic, and distributed decision-making systems.
