Circuit to prepare the \(^{18}\)O ground state. X gates prepare the reference state and FSWAP gates change the basis so that pool-operator exponentials act on adjacent qubits. Multiqubit gates in boxes are defined as \(U_{rs}^{pq}(\theta )\equiv e^{i\theta T_{rs}^{pq}}\) and \(\theta _0=-\,0.157263\), \(\theta _1=-\,0.437238\), \(\theta _2=0.604663\), \(\theta _3=0.214431\), \(\theta _4=-\,0.785469\).
