  The current advances in the field of ultra-cold atoms and atomic traps recall
new controllable long-range interactions. These interactions are expected to
extend the range of realizable quantum algorithms as well as providing new
control mechanisms for the new types of quantum matters. This article presents
special inter-atomic interactions between Rydberg-dressed atoms by manipulating
lasers' line-width. The new interaction features a hybrid spatial profile
containing plateaus and Gaussian peaks. Combined with dynamic individual
control over the sign and strength of these interaction elements, the Rydberg
noisy-dressing (RnD) scheme provides a valuable interaction toolbox for quantum
technology. As an example, RnD's application in making stable gigantic 3D
soliton molecules and in the formation of quasi-periodic droplet-crystals are
discussed.
