This experimental research program will focus on the properties of Rydberg states of ultracold atoms inside a Holographic Atom Trap (HAT). Having achieved atom densities in excess of 10^15 atoms per cubic centimeter, and cloud sizes of 8 microns or less using evaporative cooling and adiabatic compression, the project will have a unique and promising laboratory for studying a variety of Rydberg phenomena. The plan is to emphasize studies of the so-called blockade effect, where the presence of even a single Rydberg atom in the trap is predicted to preclude excitation of additional Rydberg atoms using the same laser fields. The blockade has tremendous promise for a variety of novel phenomena such as fast quantum state detection and transmission, single photon and single atom sources, and as an entanglement mechanism for neutral atom quantum computation. The broader impact of the program is in the significant undergraduate involvement.

该实验研究计划将集中在全息原子阱（HAT）中超冷原子的里德伯态的性质。 在利用蒸发冷却和绝热压缩实现了超过每立方厘米10^15个原子的原子密度和8微米或更小的云尺寸之后，该项目将拥有一个独特而有前途的实验室来研究各种里德伯现象。该计划是强调所谓的封锁效应的研究，其中即使是一个单一的里德伯原子在陷阱中的存在被预测排除使用相同的激光场激发额外的里德伯原子。封锁对于各种新现象具有巨大的希望，例如快速量子态检测和传输，单光子和单原子源，以及作为中性原子量子计算的纠缠机制。该计划的更广泛的影响是在显着的本科生参与。
