Experimental demonstration that two copies of a biseparable three-qubit state exhibit genuine multipartite entanglement when combined on a trapped-ion device.
Theoretical comparison of three CZ-gate schemes for 171Yb ions in YVO4 shows photon-interference protocol has best fidelity scaling with cooperativity while magnetic dipolar offers fast deterministic operation if ions can be localized closely.
