Query: Laser Trapping of Circular Rydberg Atoms   Rydberg atoms are remarkable tools for quantum simulation and computation.
They are the focus of an intense experimental activity mainly based on
low-angular-momentum Rydberg states. Unfortunately, atomic motion and levels
lifetime limit the experimental time-scale to about 100$\mu$s. Here, we
demonstrate laser trapping of long-lived circular Rydberg states for up to
10ms. Our method is very general and opens many opportunities for quantum
simulation. The 10ms trapping time corresponds to thousands of interaction
cycles in a circular-state-based quantum simulator. It is also promising for
quantum metrology and quantum information with Rydberg atoms.
