Optical clock arrays for quantum metrology

该项目的目标是通过实验研究被称为压缩态的量子态是否可以用于提高基于锶原子光学跃迁的下一代原子钟的性能。为了做到这一点，我们将创建单个原子的三维阵列，这些原子被捕获在被称为光镊子的聚焦激光光束中。通过利用里德堡态中原子之间的远程相互作用，这些原子将被耦合在一起。相关的主题领域是原子物理、量子光学和精密测量。

The goal of this project is to investigate experimentally whether quantum states known as squeezed states can be used to enhance the performance of the next generation of atomic clocks that are based on optical transitions in strontium atoms. To do this, we will create three dimensional arrays of individual atoms trapped in focussed laser beams known as optical tweezers. The atoms will be coupled together by exploiting the long-range interaction between atoms in Rydberg states. The relevant thematic areas are atomic physics, quantum optics and precision measurement.
