Predict the output
Run 1024 seeded shots of this circuit (seed 8842). Predict how many give |000⟩. Estimate P(|000⟩) × 1024 and pick the closest option.
const c = circuit(3); // Periodic superposition: (|000>+|010>+|100>+|110>)/2 c.h(0); c.h(1); // Inverse QFT (adjoint of QFT including bit-reversal swap) c.swap(0, 2); c.h(2); c.cp(-Math.PI / 2, 2, 1); c.h(1); c.cp(-Math.PI / 4, 2, 0); c.cp(-Math.PI / 2, 1, 0); c.h(0); return c;
Commit your prediction for counts of |000⟩ over 1024 shots — then run it.
