Multiple choice
Run this circuit, then measure. With what probability do you get |10⟩?
⚛ The apparatus
const theta = Math.PI / 2;
const c = circuit(2);
c.x(1);            // |01>
c.cx(1, 0);
c.ry(theta / 2, 1);
c.cx(0, 1);
c.ry(-theta / 2, 1);
c.cx(0, 1);
c.cx(1, 0);
return c;

Commit your prediction for P(|10⟩) — then run it.
