Experimental verification of Entanglement Witness of Dicke state on IBM QPU
An entanglement witness is necessary to characterize genuine multipartite entan-gled states. We theoretically derive the entanglement witness for the four-qubit Dicke state. A negative expectation value confirms genuine multipartite entanglement. Our witness was experimentally verified on IBM QPU, with and without error mitigation techniques.
