  Approximate counterdiabatic (CD) protocols are a powerful tool to enhance
quantum adiabatic processes that allow to reliably manipulate quantum systems
on short time scales. However, implementing CD protocols entails the
introduction of additional control fields in the Hamiltonian, often associated
with highly non-local multi-body interactions. Here, we introduce a novel
variational rotated ansatz (RA) to systematically generate experimentally
accessible approximate CD protocols. We numerically benchmark our approach on
state preparation and adiabatic quantum computing algorithms, and find that
using RA protocols significantly enhances their performances.
