Thomas Long will give a talk titled “Latin America and the Liberal International Order: Historical Trajectories and Contemporary Challenges.” He is an assistant professor in the Department of Politics and International Studies at the University of Warwick and is Fulbright Visiting Professor at the Instituto de Ciencia Política of the Pontificia Universidad Católica of Chile. He is also an affiliated professor at the Centro de Investigación y Docencia Económicas (CIDE) in Mexico City. He holds a Ph.D. in international relations from American University and was nominated for both the “Brilliant Newcomer” and “Student Experience” awards at the University of Warwick. Long’s research interests include U.S.-Latin American relations, Latin American foreign policy, North America and the dynamics of asymmetrical international relations. His first book, Latin America Confronts the United States: Asymmetry and Influence (Cambridge University Press, 2015) was named one of the best books of 2016 by Foreign Affairs.
This event is free and open to the public and is sponsored by the Department of Political Science at Amherst College along with additional funds from the Lamont Fund and the Lurcy Endowment.
Andrew Eddins '11 from the Department of Physics at the University of California, Berkeley, will discuss "Superconducting Circuits for Quantum Metrology with Squeezed Microwaves."
Abstract: Intensive development of superconducting circuits has been driven by the prospect of quantum-computing applications. While most agree that practical quantum computers remain many years away, the interim development of quantum circuits opens previously inaccessible classes of quantum-physics experiments. For example, circuits have recently emerged as a powerful platform for studying the interaction of matter with a distinctly quantum type of radiation known as “squeezed” radiation, famous for enabling precision beyond the limit set by intrinsic quantum uncertainty, yet notoriously difficult to couple to in conventional AMO setups using lasers and atoms. In this talk, I will present a brief introduction to superconducting circuits, then discuss two experiments leveraging the circuit environment’s compatibility with squeezing, first studying how squeezing modifies fluorescence spectra of an atomic system, and second investigating the use of squeezing for the readout of a quantum-bit, the building block of proposed quantum computers. The results include the first confirmation of two nearly three-decade-old predictions of quantum optics, and the first demonstration that squeezed microwaves can improve the signal-to-noise ratio of quantum-bit readout."
