Efficient Quantum Network Communication Using Optimized Entanglement Swapping Trees

Efficient Quantum Network Communication Using Optimized Entanglement Swapping Trees Quantum network communication is challenging, as the no-cloning theorem in the quantum regime makes many classical techniques inapplicable; in particular, the direct transmission of qubit states over long distances is infeasible due to unrecoverable errors. For the long-distance communication of unknown quantum states, the only viable communication approach (assuming local operations and classical communications...
