Quantum Solution

Quantum solution to an 18th century puzzle

(ORDO NEWS) — Euler’s 243-year-old mathematical puzzle, which is not known to have a classical solution, has been found to be solvable if objects arranged in a square grid exhibit quantum behavior. It consists in finding a way to arrange objects in a grid so that their properties are not repeated in any row or column. A mathematical problem that does not have a classical solution turns out to be…
