Description
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 CE, and the classical capacity C1 of a spin chain with ferromagnetic Heisenberg interactions
