Predict the output
Sampling this circuit 1024 times on the seeded simulator (seed 1476), how many shots land on |000⟩? Estimate P(|000⟩) × 1024 and pick the closest option.
// H on qubit 0 makes (|0> + |1>)/sqrt2 on the first qubit; // CNOT(0->1) and CNOT(0->2) entangle the rest, giving (|000> + |111>)/sqrt2. const c = circuit(3); c.h(0); c.cx(0, 1); c.cx(0, 2); return c;
Commit your prediction for counts of |000⟩ over 1024 shots — then run it.
