- Abstract: We implement and characterize a protocol that enables arbitrary local
controls in a dipolar atom array, where the degree of freedom is encoded in a
pair of Rydberg states. Our approach relies on a combination of local
addressing beams and global microwave fields. Using this method, we directly
prepare two different types of three-atom entangled states, including a W-state
and a state exhibiting finite chirality. We verify the nature of the underlying
entanglement by performing quantum state tomography. Finally, leveraging our
ability to measure multi-basis, multi-body observables, we explore the
adiabatic preparation of low-energy states in a frustrated geometry consisting
of a pair of triangular plaquettes. By using local addressing to tune the
symmetry of the initial state, we demonstrate the ability to prepare correlated
states distinguished only by correlations of their chirality (a fundamentally
six-body observable). Our protocol is generic, allowing for rotations on
arbitrary subgroups of atoms within the array at arbitrary times during the
experiment; this extends the scope of capabilities for quantum simulations of
the dipolar XY model.
