Which limit arises from shared entanglement exceeding a repeater's quantum capacity?

💡 Explanation

Quantum entanglement causes fidelity degradation in quantum repeaters because errors build when attempting to distribute entangled qubits repeatedly utilizing entanglement swapping; therefore, optimal quantum communication decreases rather than improves bandwidth, under these fidelity constraints.
