Bad Qubits — Learn Quantum by Doing

Multiple choice

After running this circuit, what is the expectation value ⟨X⟩ of qubit 0 (its Bloch X-component)?

⚛ The apparatus

const c = circuit(3);
c.h(0);
c.cp(Math.PI / 2, 0, 1);
c.cp(Math.PI / 4, 0, 2);
c.h(1);
c.cp(Math.PI / 2, 1, 2);
c.h(2);
return c;

Commit your prediction for ⟨X⟩ of qubit 0 — then run it.
