Diagnosing Entanglement Using Neutrons

Caption: For simplicity, the team focused on a square of spins, the tiny bar magnets associated with the electrons in the copper atoms in the organometallic material studied by the researchers. The left (c) shows a calculated neutron image for these spins when they behave as classical objects (a), while the right (d) shows the image when they are entangled (b). The images are dramatically different in the two cases, taking the form of a nearly circular spot for the classical case and a cross for the quantum, entangled state.
