| contents | Given a finite lifetime, a ubiquitous challenge in quantum systems is how to prepare a target state in the shortest possible time. This issue is particularly relevant for Rydberg atom arrays in optical tweezers where the dephasing time is typically restricted to a few microseconds. In this work, we develop a rapid passage to ordered many-body states in a Rydberg atomic chain, which allows the transition of the system to various ordered phases in the phase diagram, such as the Z$_2$-, Z$_3$-, and Z$_4$-ordered antiferromagnetic states. Our scheme ramps the parameter in a "non-adiabatic to quasi-adiabatic to non-adiabatic (NQN)" manner. The NQN configuration significantly reduces the time cost required for the state preparation using entirely adiabatic methods, and is generally appliable to sizable number of atoms. Moreover, we experimentally validate the NQN scheme on the neutral-atom quantum cloud computer Aquila. |
