Error robust quantum logic for superconducting circuits

Superconducting quantum computers differ substantially in the physical implementation of quantum logic operations, and therefore exhibit divergent error processes across hardware systems. In this talk we describe error modeling identifying dominant error channels in superconducting circuits implementing both parametrically activated and cross-resonance two-qubit gates. We use these insights to derive new classes of error-robust controls which combine modulation of both fields mediating the entangling operation and unitary operations applied to individual qubits. We present both analytic and numerically optimized solutions which are designed to reduce sensitivity to time-varying noise in critical system parameters by orders of magnitude.
