Addendum to “Quantum wireless multihop communication based on arbitrary Bell pairs and teleportation”
Kan Wang, Yan-Xiao Gong, Xutao Yu, Shengli Lu · Physical Review A · 2014
In our previous work [Phys. Rev. A 89, 022329 (2014)], we proposed a teleportation-based quantum communication scheme in a quantum wireless multihop network with arbitrary types of Bell pairs shared between adjacent nodes. Here we revised the scheme by introducing a result-mapping method for halving the classical communication cost, with which the source and intermediate nodes map the measurement outcomes to those corresponding to the target Bell pair type assigned by the destination node. A routing protocol is utilized to piggyback the target Bell pair type notification information which introduces no extra communication cost.
