BookmarkScienceDaily (Jan. 30, 2009) — Dr. Ting Yu, an Associate Professor for the Schaefer School of Engineering & Science at Stevens Institute of Technology has co-authored a study in the journal Science examining new developments in the dynamical behavior of quantum systems.
Yu, who works in the department of Physics and Engineering Physics, writes about a new development in the dynamical behavior of entanglement of quantum systems.
"The surprising discovery that correlation between two quantum units of information called qubits can be degraded by environmental noise in a way not seen previously in studies of dissipation," writes Yu. "This new route for dissipation attacks quantum entanglement, the essential resource for quantum information as well as the central feature in the Einstein-Podolsky-Rosen so-called paradox and in discussions of the fate of Schrödinger's cat."
The article reviews recent progress in studies focused on this phenomenon, labeled ESD, which stands for early-stage disentanglement or, more frequently, entanglement sudden death.
As he has in the past, Yu paired up with Dr. Joseph H. Eberly, a member of the Center for Quantum Information and Director of the Rochester Theory Center for Optical Science and Engineering at the University of Rochester.
"Quantum information science is an emerging field that may bring about revolutionary technological advances in the 21st century. At Stevens we emphasize the importance of quantum information science," said Yu. "This is a very exciting research area and Stevens offers an environment where we can continue to advance our research."
