Controlling Entanglement for Enhanced Dense Coding in Anisotropic Floquet‐Driven Two‐Qutrit System

ABSTRACT High‐dimensional quantum systems offer a promising pathway to exceed information capacity limits, yet realizing robust dense coding remains challenged by decoherence. While Floquet engineering allows dynamic control, its potential in high‐spin systems is not fully exploited. Here, presenting a novel integration of periodic driving with higher‐dimensional thermal spin models, we investigate the dense coding capacity of a two‐qutrit Heisenberg XXZ system with single‐ion anisotropy.
