Scalable High-Dimensional Multipartite Entanglement with Trapped Ions
Harsh Vardhan Upadhyay, Sanket Kumar Tripathy, Ting Rei Tan +2
We propose a protocol for the preparation of generalized Greenberger-Horne-Zeilinger (GHZ) states of atoms each with or internal levels. We generalize the celebrated…
