Multiple choice
Run this circuit. What is qubit 0's Bloch X-component — the expectation value ⟨X⟩?
const c = circuit(1); c.h(0); c.z(0); return c;
Commit your prediction for ⟨X⟩ of qubit 0 — then run it.
const c = circuit(1); c.h(0); c.z(0); return c;
Commit your prediction for ⟨X⟩ of qubit 0 — then run it.
