Title: Two-excitation routing via linear quantum channels
Authors: Tony John George Apollaro and Wayne Jordan Chetcuti
Abstract summary: We apply the perturbative transfer scheme to a two-excitation routing protocol on a network where multiple two-receivers block are coupled to a linear chain. We find that the protocol allows for efficient two-excitation routing on a fermionic network, although for a spin-$frac12$ network only a limited region of the network is suitable for high-quality routing.

Abstract: Routing quantum information among different nodes in a network is a fundamental prerequisite for a quantum internet. While single-qubit routing has been largely addressed, many-qubit routing protocols have not been intensively investigated so far. Building on the many-excitation transfer protocol in arXiv:1911.12211, we apply the perturbative transfer scheme to a two-excitation routing protocol on a network where multiple two-receivers block are coupled to a linear chain. We address both the case of switchable and permanent couplings between the receivers and the chain. We find that the protocol allows for efficient two-excitation routing on a fermionic network, although for a spin-$\frac{1}{2}$ network only a limited region of the network is suitable for high-quality routing.
