Remote Preparation and Distribution of Bipartite Entangled States
arXiv:quant-ph/0410016 · doi:10.1103/PhysRevLett.93.260501
Abstract
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.
