Abstract
We investigate the information transmission capabilities of a dissipative three-mode bosonic quantum system by analyzing its associated quantum channel. The study focuses on the evaluation of coherent information and entanglement-assisted classical capacity under both pure and mixed input states. The system dynamics are modeled using a Lindblad master equation, allowing us to capture the effects of environmental decoherence and dissipation. For pure states, the two capacity measures exhibit close agreement, while for mixed states a clear separation emerges due to the contribution of input entropy. The results further reveal a nontrivial dependence on evolution time and Hilbert space dimension, highlighting the competing roles of coherent interactions and noise. These findings provide insight into the fundamental limits of information transmission in realistic open quantum systems.
