THE QUIET LATTICE / A REPAIR PUZZLE

Qubit QuiltStitch the noise into silence.

Touch a link to flip its two endpoints.
Make every spark quiet. Keep both seals.

SMALL MOVES, GLOBAL CONSEQUENCES

Quiet points aren’t the whole story.

Each quilt folds around in both directions. A wrap link also flips its direction’s seal. A loop can silence every point and still cross a seam the wrong number of times.

YOUR COLLECTION

0 / 8 quilts sealed

Gold: use a cheapest repair. Silver: finish within the thread budget. Progress stays in this browser.

Make a little quiet.

1. Every glowing coral point is noisy. Click a numbered link to flip both endpoint points. A selected link glows mint; click it again to remove it.

2. The number is its thread cost. Your selected links must fit the budget shown above the quilt.

3. The ↻ links at the right and bottom wrap to the first point in that row or column. They flip the East or South seal too. Bring both seal readouts to EVEN.

4. With no noise, both seals EVEN, and enough thread, press Seal the quilt. Some starting seals are ODD: those need an odd number of corresponding wrap links.

Keyboard: Tab to any link; Space or Enter toggles it. All menus and actions work with Tab and Enter. Undo and Reset are always available. Guidance points toward one exact cheapest repair and can remove a mistaken link.

Quantum error correction turns noisy measurements into repair chains. This toy borrows the parity and wrapping ideas; it omits quantum states, measurement time and realistic hardware noise.
