我们在钠玻色-爱因斯坦凝聚体（BEC）中实验证明了一种基于种子初态的新型自旋混合干涉术。播种是有用的，因为它加速了纠缠对的产生，允许许多碰撞快速发生，在干涉仪的臂中产生大量的粒子。我们的干涉仪的纠缠探测态是通过F= 1旋量BEC中的自旋交换碰撞产生的，其中具有磁量子数的原子对
We experimentally demonstrate a new type of spin-mixing interferometry in sodium Bose–Einstein condensates (BECs) based on seeded initial states. Seeding is useful because it speeds up the generation of entangled pairs, allowing many collisions to take place quickly, creating large populations in the arms of the interferometer. The entangled probe states of our interferometer are generated via spin-exchange collisions in F= 1 spinor BECs, where pairs of atoms with the magnetic quantum number
