Fig. 2: Our proposed entanglement swapping policies for multiplexed repeater chains.

a Illustrative example of the FN SWAP-ASAP policy. Links on both sides of the kth node are ranked separately on the basis of their lengths. The longest link is given a rank of 1, while shortest is ranked 3. For entanglement swapping, we pair links of rank 1, which would result in the longest possible link. Next links of rank 2 are connected, and so on. (b) In the case of the SN SWAP-ASAP policy, link rankings are based on their ages.
