Tips & Traps: An Interesting Setup for Light-Matter Interaction
April 10th, 2019 KLARA THEOPHILO The Optics and Photonics Research Center (Cepof)
IFSC, University of São Paulo (USP)

The atom-photon interaction is one of the basic principles of quantum computation and communication. Therefore, a continuous effort has been done to improve control and efficiency in this kind of experiment. On this talk, we shall discuss a promising platform for light matter interaction: Trapped atoms combined with high finesse fiber tip cavities. The ultimate goal is to reach the single photon/single atom regime of interaction with the capability of accessing and manipulating the quantum state of the system in a controlled manner.

We will explore two experiments, one which the cavity was designed to interact with neutral atoms trapped in an optical tweezers and another which the cavity was designed to interact with single ions trapped in a 3D segmented trap. In both, we describe the process of obtaining a fiber cavity, as well as the trapping techniques that were implemented.
