Speaker: John A. Rogers, Northwestern University
Talk Title: Director of the Querrey-Simpson Institute for Bioelectronics
Series: Munushian Seminar Series
Abstract: A remarkable feature of modern integrated circuit technology is its ability to operate in a stable fashion, almost indefinitely, without physical or chemical change. Recently developed classes of electronic materials create an opportunity to engineer the opposite outcome, in the form of 'transient' devices that dissolve, disintegrate, degrade or otherwise physically disappear at triggered times or with controlled rates. Water-soluble classes of transient electronic devices serve as the foundations for applications in zero-impact environmental monitors, 'green' consumer electronic gadgetry and bio-resorbable medical implants. This talk describes the foundational concepts in materials science, electrical engineering and assembly processes for bio/ecoresorbable electronics in a variety of formats and with a range of functions. Bioresorbable wireless stimulators that accelerate neuroregeneration of injured peripheral nerves and pacemakers that minimize risks after cardiac surgeries represent some recent system level examples.
Biography: Professor John A. Rogers obtained BA and BS degrees in chemistry and in physics from the University of Texas, Austin, in 1989. From MIT, he received SM degrees in physics and in chemistry in 1992 and the PhD degree in physical chemistry in 1995. From 1995 to 1997, Rogers was a Junior Fellow in the Harvard University Society of Fellows. He joined Bell Laboratories as a Member of Technical Staff in 1997 and then served as Director of the Condensed Matter Physics Research Department from the end of 2000 to 2002. He then spent thirteen years on the faculty at University of Illinois, most recently as the Swanlund Chair Professor and Director of the Seitz Materials Research Laboratory. In the Fall of 2016, he moved to Northwestern University where he is Director of the recently endowed Querrey-Simpson Institute for Bioelectronics. He has co-authored nearly 900 papers and his co-inventor on more than 100 patents. His research has been recognized by many awards, including a MacArthur Fellowship (2009), the Lemelson-MIT Prize (2011), the Smithsonian Award for American Ingenuity in the Physical Sciences (2013), the Benjamin Franklin Medal from the Franklin Institute (2019), and a Guggenheim Fellowship (2021). He is a member of the National Academy of Engineering, the National Academy of Sciences, the National Academy of Medicine and the American Academy of Arts and Sciences.

Talk Title: A Hybrid Platform for Quantum Computing
Series: Nano Science & Technology
Abstract: Material defects are ubiquitous. Seven decades ago, defects challenged the new-born semiconductor industry, and today they are one of the major roadblocks for quantum technologies. Solid-state quantum devices, in particular, superconducting qubits, stand out as one of the leading platforms for fault-tolerant quantum computing. However, the performance of superconducting qubits is limited by the presence of various microscopic forms of two-level state (TLS) defects in the amorphous surfaces of the materials that make up the qubits. Previous attempts to address this issue mostly focused on circuit designs that reduced the negative impact of TLS, but advancements have plateaued since around 2012. In this seminar, I will introduce an orthogonal approach that engineers the TLS into a highly useful quantum resource that could positively impact the superconducting qubit's performance. First, I will introduce a hybrid platform which utilizes acoustic bandgap metamaterials to structure phonon modes and significantly enhance the TLS lifetime. Next, I will discuss quantum sensing techniques developed for color centers in diamond, and their applications to this hybrid system to gain further insights into the defect physics. Lastly, I will discuss the prospects of quantum computing based on the hybrid platform.
Biography: Mo Chen is a postdoctoral scholar in the Department of Applied Physics and the Institute for Quantum Information and Matter at the California Institute of Technology. He received his B.S. in Optics from Fudan University in 2012 and his S.M. and Ph.D. in Mechanical Engineering from the Massachusetts Institute of Technology in 2015 and 2020, respectively. His research interests are focused on gaining a fundamental understanding of device physics and applying that knowledge to engineer novel quantum devices, such as qubits, quantum sensors, and quantum memories.
