纠缠对于许多量子应用是至关重要的，包括量子信息处理、量子模拟和量子增强传感。由于其丰富的内部结构和相互作用，分子被认为是一个很有前途的量子科学平台。然而，单独控制的分子的确定性纠缠一直是一个长期存在的实验挑战。我们演示了单独制备的分子的按需纠缠。利用可重构光钳阵列制备的分子对之间的电偶极相互作用，我们确定地产生了贝尔分子对。我们的结果展示了量子应用所需的关键构件，并可能推进使用俘获分子的量子增强基础物理测试。
Entanglement is crucial to many quantum applications, including quantum information processing, quantum simulation, and quantum-enhanced sensing. Because of their rich internal structure and interactions, molecules have been proposed as a promising platform for quantum science. Deterministic entanglement of individually controlled molecules has nevertheless been a long-standing experimental challenge. We demonstrate ondemand entanglement of individually prepared molecules. Using the electric dipolar interaction between pairs of molecules prepared by using a reconfigurable optical tweezer array, we deterministically created Bell pairs of molecules. Our results demonstrate the key building blocks needed for quantum applications and may advance quantum-enhanced fundamental physics tests that use trapped molecules.
