Multiple choice
This circuit is measured once in the computational basis. What is P(|0⟩)?
const phi = 1.1; const c = circuit(1); c.rx(phi, 0); // input |psi> c.x(0); // byproduct X^s, s = 1 c.x(0); // feed-forward correction X^s, s = 1 (X is its own inverse) return c;
Commit your prediction for P(|0⟩) — then run it.
