Predict the output
Run 1024 seeded shots of this circuit (seed 9451). Predict how many give |01⟩. Estimate P(|01⟩) × 1024 and pick the closest option.
const theta = Math.PI / 3; const c = circuit(2); c.x(1); // |01>: one excitation c.cx(1, 0); // controlled-RY(theta), control 0, target 1 c.ry(theta / 2, 1); c.cx(0, 1); c.ry(-theta / 2, 1); c.cx(0, 1); c.cx(1, 0); return c;
Commit your prediction for counts of |01⟩ over 1024 shots — then run it.
