摘要：

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 Q, the entanglement assisted capacity C-E, and the classical capacity C-1 of a spin chain with ferromagnetic Heisenberg interactions.
