Abstract
An iterative method is provided for progressively building an end-to-end entanglement between qubits in first and second end nodes () of a chain of nodes whose intermediate nodes () are quantum repeaters. At each iteration, a current operative repeater () of the chain merges an entanglement existing between qubits in the first end node () and the operative repeater, with a local entanglement formed between qubits in the operative repeater and its neighbor node towards the second end node (). For the first iteration, the operative repeater is the neighbor of the first end node (); thereafter, for each new iteration the operative repeater shifts one node further along the chain toward the second end node (). A quantum repeater adapted for implementing this method is also provided.
