Multiple choice
This circuit prepares qubit 0 in some state. What expectation value ⟨X⟩ does it have along the Bloch X-axis?
const c = circuit(2); c.h(0); c.x(1); c.measure(); return c;
Commit your prediction for ⟨X⟩ of qubit 0 — then run it.
const c = circuit(2); c.h(0); c.x(1); c.measure(); return c;
