Predict the output
Run 1024 seeded shots of this circuit (seed 556). Predict how many give |00⟩. Estimate P(|00⟩) × 1024 and pick the closest option.
const theta = Math.PI / 6; const c = circuit(2); // 1. prepare GHZ c.h(0); c.cx(0, 1); // 2. encode the phase on both qubits c.p(theta, 0); c.p(theta, 1); // 3. decode back onto qubit 0 c.cx(0, 1); c.h(0); // 4. measure c.measure(); return c;
Commit your prediction for counts of |00⟩ over 1024 shots — then run it.
