Schematic circuit decomposition of one layer of the UCCSD ansatz in first-order Trotterization. We use the same coloring scheme as for the previous figures; XX gates in green, YY gates in red, Rz gates in blue, local Cliffords in white if they are due to the parity string, gray if they account for odd numbers of qubits in the interaction. Note that some adjacent local Clifford gates cancel out and are only explicitly depicted for the sake of clarity.
