Abstract
Information capacities achievable in the multi-parallel-use scenarios are employed to characterize the quantum correlations in unmodulated spin chains. By studying the qubit amplitude damping channel, we calculate the quantum capacity , the entanglement assisted capacity , and the classical capacity of a spin chain with ferromagnetic Heisenberg interactions.
