Extracting GHZ states from linear cluster states
Extracting GHZ states from linear cluster states
Quantum information processing architectures typically only allow for nearest-neighbor entanglement creation. In many cases, this prevents the direct generation of $\mathrm{GHZ}$ states, which are commonly used for many communication and computation tasks. Here, we show how to obtain $\mathrm{GHZ}$ states between nodes in a network that are connected in a …
