Multiple choice
After running this circuit, what is the expectation value ⟨X⟩ of qubit 0 (its Bloch X-component)?
const c = circuit(3); c.h(2); c.cp(-Math.PI / 2, 1, 2); c.h(1); c.cp(-Math.PI / 4, 0, 2); c.cp(-Math.PI / 2, 0, 1); c.h(0); return c;
Commit your prediction for ⟨X⟩ of qubit 0 — then run it.
