Rapid passage to ordered states in Rydberg-atom arrays

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 ${\mathrm{Z}}_{2}$-, ${\mathrm{Z}}_{3}$-, and ${\mathrm{Z}}_{4}$-ordered antiferromagnetic states. Our scheme ramps the parameter in a ``nonadiabatic to quasi-adiabatic to nonadiabatic (NQN)'' manner. The NQN configuration significantly reduces the time cost required for the state preparation using entirely adiabatic methods and is generally applicable to a sizable number of atoms. Moreover, we experimentally validate the NQN scheme on the neutral-atom quantum cloud computer Aquila.
