Predict the output
This circuit is sampled for 1024 shots on the seeded simulator (seed 2898). How many of the shots come out |00⟩? Estimate P(|00⟩) × 1024 and pick the closest option.
// H on qubit 0 makes (1/sqrt2)(|00> + |10>); CNOT(0->1) flips target when // control is 1, sending |10> -> |11>, giving the Bell state |Phi+>. const c = circuit(2); c.h(0); c.cx(0, 1); return c;
Commit your prediction for counts of |00⟩ over 1024 shots — then run it.
