Robustness of a universal gate set implementation in transmon systems via Chopped Random Basis optimal control
arXiv:2207.13447 · doi:10.1016/j.physleta.2022.128119
Abstract
We numerically study the implementation of a universal two-qubit gate set, composed of CNOT, Hadamard, phase and gates, for transmon-based systems. The control signals to implement such gates are obtained using the Chopped Random Basis optimal control technique, with a target gate infidelity of . During the optimization processes we account for the leakage toward non-computational states, an important non-ideality affecting transmon qubits. We also test and benchmark the optimal control solutions against the introduction of Gaussian white noise and spectral distortion, two key non-idealities that affect the control signals in transmon systems.
