论文摘要
三体förster共振$ {\ rm 3} \ times np_ {3/2} \ to ns_ {1/2} +(n +1)s_ {1/2} +np_ {1/2} +np_ {3/2}^{*}^{**} $由DC电场控制了DC电场,由DC电场造成了几个Counder的作者。这种潜在在三量量子门上进行潜在应用的缺点之一是两体förster共振$ {\ rm 2} \ times np_ {3/2} {3/2} \ to ns_ {1/2} +(n +1)s_ {1/2}的可能性仅适用于他们的可能性。 $ n \ le 38 $。在本文中,我们提出和分析了新型$ {\ rm 3} \ times np_ {3/2} \ to ns_ {1/2} +(n +1)s_ {1/2} +np_ {1/2},$对unutial to unterial to unterized to unterial $ n $ ns_ {1/2} +(n +1)s_ {1/2} +(n +1)s_ {1/2} +(n +1),$可用于Quyt unteragy $ n $。它的特定特征还是,第三个原子转变为具有不同的总角矩$ j = 1/2 $的状态,该状态没有鲜明的结构,因此完全不存在两体的共振。数值计算表明,对于不太强烈的相互作用,可以观察到集体状态人群的连贯的三体振荡,这对于开发由电场控制的三个Qubit量子门的新方案非常有意义。
The three-body Förster resonances ${\rm 3}\times nP_{3/2} \to nS_{1/2} +(n+1)S_{1/2} +nP_{3/2}^{*} $ controlled by a dc electric field were realized earlier by the authors in an ensemble of several cold Rydberg Rb atoms. One of the drawbacks of such resonances for potential application in three-qubit quantum gates is the proximity of the two-body Förster resonance ${\rm 2}\times nP_{3/2} \to nS_{1/2} +(n+1)S_{1/2}, $ as well as the possibility of their implementation only for states with values of the principal quantum numbers $n\le 38$. In this paper we propose and analyze a three-body resonance of a new type ${\rm 3}\times nP_{3/2} \to nS_{1/2} +(n+1)S_{1/2} +nP_{1/2} , $ which can be realized for arbitrary $n$. Its specific feature is also that the third atom transits into a state with a different total angular moment $J=1/2$, which has no Stark structure, so that the two-body resonance is completely absent. Numerical calculations showed that for not too strong interaction, it is possible to observe coherent three-body oscillation of the populations of collective states, which is of interest for developing new schemes of three-qubit quantum gates controlled by an electric field.
