Multiple choice
For this circuit, what is the probability that measuring all 2 qubits yields exactly |11⟩ (qubit 0 leftmost)?
const theta0 = Math.PI / 3; const theta1 = Math.PI / 4; const c = circuit(2); c.ry(theta0, 0); c.ry(theta1, 1); c.cx(0, 1); return c;
Commit your prediction for P(|11⟩) — then run it.
