Re-thinking our analog quantum simulation for the purpose of quantum circuits, we can represent the sodium atoms as a very long spin state \(\left|\psi_N\right\rangle\). The observable outcomes are \(L_z=-\frac{N}{2},\cdots,\frac{N}{2}\), where \(N\sim10^5\) is the number of sodium atoms. On a quantum computer this should be compared to a qubit, for which we can only measure two outcomes \(L_z=\pm\frac{1}{2}\).
