Adiabatic echo protocols for robust quantum many-body state preparation

Understand

Entangled many-body states are a key resource for quantum technologies.

• Yet their preparation through analog control of interacting quantum systems is often hindered by experimental imperfections.
• Here, we introduce the adiabatic echo protocol, a general approach to state preparation designed to suppress the effect of static perturbations.
• We provide an analytical understanding of its robustness in terms of dynamically engineered destructive interference.
