Predict the output
On the seeded simulator (seed 2533), this circuit runs for 1024 shots. About how many come out |0000⟩? Estimate P(|0000⟩) × 1024 and pick the closest option.
const c = circuit(4); c.h(0); c.cx(0, 1); c.cx(1, 2); c.cx(2, 3); return c;
Commit your prediction for counts of |0000⟩ over 1024 shots — then run it.
