ABSTRACT: 

Cold atoms trapped in arrays of optical tweezers are today considered a very versatile platform for quantum science experiments. We will introduce the basic techniques underlying these experiments and show how one can exploit different types of interactions between Rydberg atoms to engineer various quantum spin models to study many-body physics. We will review some of the most recent results obtained using this platform.

BIO:
Daniel Barredo completed his PhD in the Surface Science laboratory at Universidad Autónoma de Madrid in 2009. He then was awarded a Marie Curie Fellowship to work with Rydberg atoms in thermal vapor cells in the group of T. Pfau in Stuttgart. He continued his research in the group of A. Browaeys at Institut d’Optique (Palaiseau), where he contributed to the development of a new platform for quantum simulation based on programmable arrays of individual atoms trapped in optical tweezers and excited to Rydberg states. This Rydberg quantum simulator can now operate with full individual control over ~200 qubits and be reliably used to tackle real world open problems in condensed-matter physics. Daniel moved to CINN (CSIC, Spain) in 2021 with a Ramón y Cajal contract to continue his research in quantum information science.
