Entanglement concentration of W-class states on nonlocal atoms using low-Q optical cavity

As one of the most striking features of quantum phenomena,quantum entanglement has been identified as a key nonlocal resource in quantum information processing such as quantum cryptography[1–3].In particular,the maximally entangled states give rise to the best fidelity in general,for instance,perfect teleportation.Nevertheless,in practical,during the transmission of quantum entanglement,a maximally entangled
