Optimal State Transfer and Entanglement Generation in Power-Law Interacting Systems
We present an optimal protocol for encoding an unknown qubit state into a multiqubit Greenberger-Horne-Zeilinger-like state and, consequently, transferring quantum information in large systems exhibiting power-law (1/r^{α}) interactions. For all power-law exponents α between d and 2d+1, where d is t...
