Multipartite entanglement transfer in spin chains

10 Jan 2020 Apollaro Tony J. G. Sanavio Claudio Chetcuti Wayne Jordan Lorenzo Salvatore

We investigate the transfer of genuine multipartite entanglement across a spin-1/2 chain with nearest-neighbor XX-type interaction. We focus on the perturbative regime, where a block of spins is weakly coupled at each edge of a quantum wire, embodying the role of a multiqubit sender and receiver, respectively... (read more)
