In this work, we assume this perspective and use optimal control tools to derive the gates required by a toy two-qubit algorithm consisting of simultaneous single-qubit gates followed by an entangling gate and, in tandem, explore the model space of superconducting quantum computer design, from dispersively coupled to strongly interacting qubits, to maximize gate fidelity. The use of perfect entangler theory provides a flexibility to the search for a two-qubit gate on a given platform and enables a comparison between designs with different entangling mechanisms, e.g. CPHASE and √iSWAP.
