For ultrafast Rydberg experiments [1], even these remaining quantum fluctuations affect the dynamics of Rydberg atoms directly interacting via the dipole-dipole coupling. To further suppress quantum fluctuations, we create squeezed state of motions that allows to push beyond the standard quantum limit of position uncertainty. The manipulation of these delicate quantum states of motion requires a much-improved control on the tweezers shape and on its homogeneity over an atomic array. I will introduce several techniques to precisely measure the shape of the tweezers by interrogating the atoms, and then adjust the computer-generated hologram creating the tweezers array.
This optimization of the hologram allows an improvement by more than one order of magnitude of the tweezers shape and opens the path for ultra-precise manipulation of atoms through the creation of squeezed state of motion or the application of “motion-echo” techniques.
