Quantum science emerged from studies of the smallest objects in nature. Today, it promises to deepen our understanding of the universe and deliver groundbreaking technology, from quantum computers to ultra-precise measuring devices to next-generation materials, with many of these advances happening at Caltech. In Conversations on the Quantum World, you will hear directly from Caltech experts about the next quantum revolution and have the opportunity to ask your own questions.

Electronics continue to shrink in size to grow in capability, speed, and efficiency. The devices that power society now rely on components engineered at the nanoscale. At such small scales, quantum effects begin to take over, exerting a powerful influence on how materials work. Industry professionals turn to physicists for answers about these seemingly confounding but critically important effects. In this event, experimental physicist Nai-Chang Yeh will share insights on what quantum materials are and why we can expect them in all our future technologies.


This is a free event, but registration is required. The first 1,000 attendees can join the Zoom webinar. Others will be provided with a YouTube link.

About the Participants

Nai-Chang YehThomas W. Hogan Professor of PhysicsNai-Chang Yeh invents powerful tools and approaches to study and engineer materials at the scale of billionths of a meter. She investigates materials with fascinating quantum properties, such as superconductors, exotic magnets, graphene, topological materials, and materials made of atomically thin sheets or wires. She is interested in their potential uses in efficient nano-electronics, optoelectronics, quantum computers, energy technologies, and other applications. Yeh previously co-directed Caltech's Kavli Nanoscience Institute for six years (2013–2019). An eager student from an early age, she was inspired by the example of her mother, a mathematics professor in Taiwan, and her doctoral adviser at MIT, Mildred Dresselhaus.

Ann MotrunichLead Writer, Caltech's Office of Strategic CommunicationsAnn Motrunich is a writer focused on advancement communications and community relations at Caltech. She received a BS from Western Washington University and an MFA in creative nonfiction from the University of Arizona. Prior to joining Caltech, she worked in scholarly publishing and communications planning and served as a park ranger in one of the most remote communities in the Pacific Northwest.

This series is presented by the Caltech Science Exchange, which brings expert insight to the scientific questions that define our time. The Science Exchange offers trustworthy answers, clear explanations, and fact-driven conversation on critical topics in science and technology.
