// 1. Define: a door with three possible destinations
const door = quantum(["forest", "castle", "cave"]);
door.superpose();  // all three destinations at once

// 2. Player shapes the state: a crystal turns the phase
function onUseCrystal(strength: number) {  // 0 to 1
  door.phase(strength);
  door.superpose();  // the paths interfere and the odds shift
}

// A key that interacts with the door ends up entangled with it
const key = quantum(["forest", "castle", "cave"]);
key.next({ when: [door.is("castle")] });
key.previous({ when: [door.is("cave")] });

// 3. Resolve: the player steps through and the state collapses
const destination = door.measure();  // "forest", "castle" or "cave"
key.measure() === destination;        // true, every time
