Decoherence-controlled collective criticality in a two-dimensional quantum Stag Hunt
This work investigates how physical decoherence channels affect collective criticality in a quantum Stag Hunt game. By mapping the game onto an Ising model, researchers found that different noise types—phase damping, depolarization, and amplitude damping—renormalize the system's effective interactions. This allows the system to switch between ordered coexistence and disordered crossovers depending on which decoherence channel is applied.
