Non-standard gates in superconducting parametric gate architectures

One of the main challenges in the realization of superconducting quantum computers is the ability to do high fidelity two-qubit entangling gates. Coupling transmon qubits with a parametrically driven tunable coupler enables fast entangling gates, but strong drives can introduce leakage and add unwanted coherent drive terms to the Hamiltonian. Targeting non-standard gates generates a family of operations that allows flexibility to pick gates with low leakage. Additionaly, extra coherent interactions do not contribute to gate infidelity. We present results on non-standard parametric entangling gates optimized for speed and leakage suppression while maintaining efficient compilation to standard two-qubit gates.
