They are also an experimental demonstration of the high degree of control that can be achieved over a 50-qubit platform with neutral atoms, holding great prospects for several applications of the second quantum revolution including quantum metrology and quantum optimization. If pushed even further in system size and fidelity, this technique might find applications in fields of broad general interest like material science or biology, solving problems that cannot be solved on any classical computer.
