Experimental realization of multipartite entanglement via quantum Fisher information in a uniform antiferromagnetic quantum spin chain
Quantum entanglement is a quantum-mechanical phenomenon where the quantum state of a many-body system with many degrees of freedom cannot be described independently of the state of each body with a given degree of freedom, no matter how far apart in space each body is. Entanglement is not only consi...
