论文摘要
为了执行少量的量子门，考虑到Rydberg原子之间的三种体谐振相互作用。到目前为止，在剖宫产或rubidium原子中发现的共振依赖于相邻的两体共振，该共振不再存在于高于$ n \ simeq 40 $的主要量子数。我们最近提出了在碱金属rydberg原子中进行新的三体相互作用共鸣的新类[P. Cheinet \ textit {等}，量子。选。 \ textbf {50}，213（2020）]，它绕开了此限制。我们在这里研究了这一新类别的三体相互作用共振与准芬氏2体相互作用共振之间的相对强度。然后，我们确定用于检测和使用这种三体相互作用的最佳情况。
Three body resonant interactions between Rydberg atoms are considered in order to perform few-body quantum gates. So far, the resonances found in cesium or rubidium atoms relied on an adjacent two-body resonance which ceases to exist for principal quantum numbers above $n \simeq 40$. We have proposed recently a new class of 3-body interaction resonances in alkali-metal Rydberg atoms [P. Cheinet \textit{et al.}, Quant. Elect. \textbf{50}, 213 (2020)], which circumvienes this limit. We investigate here the relative strength between this new class of 3-body interaction resonance and quasi-forbidden 2-body interaction resonances in rubidium and cesium Rydberg atoms. We then identify the best case scenario for detecting and using this 3-body interaction.
