Multiple choice
This circuit prepares qubit 0 in some state. What expectation value ⟨Z⟩ does it have along the Bloch Z-axis?
const c = circuit(2); const x = [0.5, 0.9]; const theta = [0.4, 1.2]; c.ry(2 * x[0], 0); c.ry(2 * x[1], 1); c.ry(theta[0], 0); c.ry(theta[1], 1); c.cx(0, 1); c.measure(); return c;
Commit your prediction for ⟨Z⟩ of qubit 0 — then run it.
