Remote Preparation and Distribution of Bipartite Entangled States
Gilad Gour, Barry Cyril Sanders · Physical Review Letters · 2004
We prove a powerful theorem for tripartite remote entanglement distribution protocols that establishes an upper bound on the amount of entanglement of formation that can be created between two single-qubit nodes of a quantum network. Our theorem also provides an operational interpretation of concurrence as a type of entanglement capacity.
