Predict the output
On the seeded simulator (seed 9175), this circuit runs for 1024 shots. About how many come out |01⟩? Estimate P(|01⟩) × 1024 and pick the closest option.
// |00> --x(1)--> |01> --h(0)--> (|01>+|11>)/sqrt2 --cx(0,1)--> (|01>+|10>)/sqrt2 // --z(0)--> (|01>-|10>)/sqrt2, the singlet. const c = circuit(2); c.x(1); c.h(0); c.cx(0, 1); c.z(0); return c;
Commit your prediction for counts of |01⟩ over 1024 shots — then run it.
