Quantum metrology with alkaline-earth atom arrays

Programmable arrays of alkaline-earth atoms have emerged as a versatile experimental platform for quantum science. Together with Rydberg interactions, control at the single-particle level makes such atom arrays ideal systems for studying how quantum entanglement can be harnessed to improve the performance of optical atomic clocks. In this talk, I will discuss recent work from JILA, where we have achieved this goal by engineering Rydberg interactions to prepare entangled states with metrological gain.
