Entanglement concentration for concatenated Greenberger-Horne-Zeiglinger state with feasible linear optics
Yu-Bo Sheng, Chang-Cheng Qu, Lan Zhou
The concatenated Greenberger-Horne-Zeiglinger (C-GHZ) state which is a new type of logic-qubit entanglement has attracted a lot of attentions recently. We present a feasible entang…
