Categories
Kevin P. O’Brien is the Emanuel E. Landsman Career Development Assistant Professor in MIT’s Department of Electrical Engineering and Computer Science and a principal investigator in the Research Laboratory of Electronics. His research focuses on engineering nonlinear and quantum-mechanical light-matter interactions at microwave frequencies using the platform of superconducting circuits. The goals are to explore quantum mechanics in engineered systems, like metamaterials, and to make quantum computing successful by developing the technology it depends on, like quantum-limited amplifiers, isolators and qubits. O’Brien earned a BS in physics from Purdue University, and a PhD in physics from the University of California, Berkeley, studying the nonlinear properties of optical metamaterials with ultrafast optics and performing theoretical work on superconducting quantum-limited amplifiers. As a postdoc at UC Berkeley he led the development of multi-qubit quantum processors.
