论文摘要
我们展示了相关的原子对来源，其特征是两个相反的动量和两个空间模式，形成钟形状态，仅涉及外部自由度。我们通过在相关的两粒子发射模式中观察到的强度挤压到-10 dB来表征发射原子束的状态。我们此外，相对于发射原子，在归一化的二阶相关函数$ g^{（2）} $中表明了真正的两粒子干扰。
We demonstrate a source for correlated pairs of atoms characterized by two opposite momenta and two spatial modes forming a Bell state only involving external degrees of freedom. We characterize the state of the emitted atom beams by observing strong number squeezing up to -10 dB in the correlated two-particle modes of emission. We furthermore demonstrate genuine two-particle interference in the normalized second-order correlation function $g^{(2)}$ relative to the emitted atoms.
