LondonEuler’s 1779 officer puzzle has no ordinary solution.
Entanglement is not a shortcut, it is what makes the arrangement exist.
A superposed officer is merely uncertain alone, but entangled officers stay undefined individually while jointly filling the 6-by-6 grid.
Latin squares already underpin error-correcting codes, a bottleneck for today’s noisy quantum machines.
