Oskar Painter and Colleagues Propose Quantum Entanglement for Motion of Microscopic Objects

12-21-09

Oskar Painter, Associate Professor of Applied Physics, along with colleagues Darrick Change, Postdoctoral Scholar at Institute for Quantum Information, and H. Jeff Kimble, William L. Valentine Professor and Professor of Physics have proposed a new paradigm that should allow scientists to observe quantum behavior in small mechanical systems. Their idea offers a new means of studying the nature of quantum superposition and entanglement in progressively larger and more complex systems. [Caltech Press Release]

DNA Origami Nanoscale Breadboards for Carbon Nanotube Circuits

11-10-09

Hareem T. Maune, a graduate student studying carbon nanotube physics, and Si-ping Han, a graduate student investigating the interactions between carbon nanotubes and DNA have developed DNA origami nanoscale breadboards for carbon nanotube circuits. "This collaborative research project is evidence of how we at Caltech select the top students in science and engineering and place them in an environment where their creativity and imagination can thrive," says Ares Rosakis, chair of the Division of Engineering and Applied Science at Caltech and Theodore von Kármán Professor of Aeronautics and Professor of Mechanical Engineering. The work of these students was supervised by: Erik Winfree, Associate Professor of Computer Science, Computation and Neural Systems, and Bioengineering; William A. Goddard III, Charles and Mary Ferkel Professor of Chemistry, Materials Science, and Applied Physics; Paul W.K. Rothemund, Senior Research Associate, and Marc Bockrath, Associate Professor of Physics at University of California Riverside. [Caltech Press Release]
