Predict the output
This circuit is sampled for 1024 shots on the seeded simulator (seed 1076). How many of the shots come out |000⟩? Estimate P(|000⟩) × 1024 and pick the closest option.
const c = circuit(3); c.h(0); // (|0>+|1>)/sqrt2 on qubit 0 c.cx(0, 1); // copy onto qubit 1 c.cx(0, 2); // copy onto qubit 2 -> (|000>+|111>)/sqrt2 return c;
Commit your prediction for counts of |000⟩ over 1024 shots — then run it.
