Rydberg atom arrays for quantum simulation, computation, and metrology

Rydberg atoms in arrays of optical tweezers open up new horizons for quantum simulation, computation, and metrology. We will explore how individual atoms can be trapped and arranged, creating customizable arrays that serve as a versatile platform for quantum applications. We will review ongoing efforts in the community to implement different spin models with hundreds of particles for simulating quantum many-body phenomena [1,2]. Furthermore, we will illustrate how entanglement in these systems can be harnessed to generate scalable spin squeezing for metrological applications [3]. Finally, we will provide perspectives on the developments of Rydberg atoms arrays for quantum computing, highlighting the ability of the platform to implement high-fidelity quantum gates and scalable quantum circuits [4].
