New Developments In Dynamical Behavior Of Quantum Systems

Summary:
Scientists have examined new developments in the dynamical behavior of quantum systems in a recent article in Science.

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 Schrφdinger'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."

Algonquin Power Goes Activist on Its Target Gas Natural

TheStreet (July 23, 2014) — When The Deal's Amanda Levin exclusively reported that Gas Natural had been talking to potential suitors, the Ohio company responded with a flat denial, claiming its board had not talked to anyone about a possible sale. Lo and behold, Canadian utility Algonquin Power and Utilities not only had approached the company, but it did it three times. Its last offer was for $13 per share as Gas Natural's was trading at a 60-day moving average of about $12.50 per share. Now Algonquin, which has a 4.9% stake in Gas Natural, has taken its case to shareholders, calling on them to back its proposals or, possibly, a change in the target's board.
