Quantum Sudoku

4×4

A Sudoku encoded as an energy-minimization problem. Generate a puzzle, then find the ground state of the same reduced QUBO objective used by the quantum solver.

Ground-state energy —

Ready. Generate a puzzle or solve this one.

Browser demo: the QUBO ground state is minimized exactly so this static GitHub Pages site stays fast and dependency-free. The PennyLane/QAOA implementation uses the same objective.
