Abstract Samples of cold Rydberg atoms have been proposed as ideal systems to perform quantum computation. This is because these atoms present ultralong-range interactions in general from 2 to 10¼m for a principal quantum number ranging between 30 and 70. Making use of various theoretical proposals such interaction using the internal states of atoms to generate entanglement, and thus create the qubit. In all these theoretical proposals, only two atoms separated by a distance R are considered. This difficult task was accomplished experimentally by two research groups in the world recently, through the use of two micro-optical dipole traps. These two groups trapped atoms, one in each trap. Despite the success, such experimental realization is complex. In this project, we propose to create spatial structures using similar but different spatial arrangements of laser beams of Rydberg state excitation. Our proposal will simplify the experimental setup and allow us to build microstructures with Rydberg atoms. These distributions allow us to observe spatial anisotropy due to interactions between Rydberg atoms. (AU) | |
