Quantum optimal control in a ZZ-free qubit architecture

ORAL

Abstract

Quantum optimal control is a powerful technique for improving the performance of quantum gates. Numerical methods, such as GRAPE, have been demonstrated to reduce infidelity of single- and two-qubit gates by several orders of magnitude. In this talk, we demonstrate the application of quantum optimal control in a newly proposed architecture in which the ZZ-interaction is inherently suppressed. We explore the parameter regimes of this system to optimize the performance of a cross-resonance gate on this architecture.
