Graduate and Postdoc Fellow Seminar: Wilson J. Yanez Parreno

What materials will be used to build my quantum computer? Silicon based and low temperature grown superconductors for quantum information applications

My name is Wilson J. Yánez Parreño and I am a postdoctoral researcher working with Chris Palmstrom. My research focuses on the synthesis of quantum materials and the development of heterostructures made of dissimilar materials to engineer novel physical behavior. During this talk I will present my postdoctoral work on the synthesis of silicon based and low temperature grown superconductors for quantum information applications using molecular beam epitaxy. I will discuss the advantages and challenges that these systems present and the approach that our lab has taken to overcome then. I will talk about superconductivity, epitaxy, transmon qubits, ultra high vacuum, microwave loss, structural disorder, and the new way we found to change the color of superconducting aluminum from completely reflective to yellow.
