Abstract

We propose a simple scheme to establish entanglement among stationary qubits based on the mechanism of resonance scattering between them and a single-spin-flip wave packet in designed spin network. It is found that through the natural dynamical evolution of an incident single-spin-flip wave packet in a spin network and the subsequent measurement of the output single-spin-flip wave packet, multipartite entangled states among n stationary qubits, Greenberger-Horne-Zeilinger (GHZ), and W states can be generated with success probabilities P_GHZ=2/|1+t^\ensuremath-n|² and P_W=|t|²/n, respectively, where t is the transmission amplitude of the near-resonance scattering.
