Multiple choice
After running this circuit, what is the expectation value ⟨X⟩ of qubit 0 (its Bloch X-component)?
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 ⟨X⟩ of qubit 0 — then run it.
