Multiple choice
For qubit 0 after this circuit, what is ⟨X⟩, the X-axis projection of its Bloch vector?
// H|0> = (1/sqrt2)(|0> + |1>) = |+>. const c = circuit(1); c.h(0); return c;
Commit your prediction for ⟨X⟩ of qubit 0 — then run it.
// H|0> = (1/sqrt2)(|0> + |1>) = |+>. const c = circuit(1); c.h(0); return c;
