Quantum Science with Tweezer Arrays

Friday August 7, 2020
1:00 pm


 Presenter:  Manuel Andres, Caltech
 Series:  CQuIC Seminars
 Abstract:  A VIRTUAL AMO SEMINAR presented in a Zoom meeting vetted by CQuIC. See https://sites.google.com/stanford.edu/virtual-amo-seminar/schedule for the meeting link.

Cold atoms in optical tweezer arrays have emerged as a versatile platform for quantum science. I will review these developments, including atom-by-atom assembly as a method to generate defect-free arrays [1] as well as quantum simulation of spin models with Rydberg atoms [2], followed by a brief discussion of current limitations. Our work at Caltech now merges these directions with control of narrow and ultra-narrow optical transitions in alkaline earth atoms. I will give an overview of new opportunities in this context and recent results from our lab: 1) A record in imaging-fidelity for neutral atoms and demonstration of narrow-line cooling in tweezers [3,4]. 2) Rydberg excitation from a meta-stable clock state, which resulted in leading fidelities for entanglement of two neutral atoms [5]. 3) Demonstration of an optical clock with single-atom detection in tweezer arrays [6].
