Predict the output
Sampling this circuit 1024 times on the seeded simulator (seed 1248), how many shots land on |0000⟩? Estimate P(|0000⟩) × 1024 and pick the closest option.
const c = circuit(4); // 1. distribute two Bell pairs c.h(0); c.cx(0, 1); c.h(2); c.cx(2, 3); // 2. bilateral CNOT (Alice and Bob each apply one locally) c.cx(0, 2); c.cx(1, 3); return c;
Commit your prediction for counts of |0000⟩ over 1024 shots — then run it.
