Dr. Ting Yu's research featured in latest issue of Science magazine

Article looks at new developments in the dynamical behavior of quantum systems

HOBOKEN, N.J. - An article co-authored by Dr. Ting Yu, an Associate Professor for the Schaefer School of Engineering & Science at Stevens Institute of Technology, is featured in the most recent edition of Science magazine.

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."

About Science magazine

Founded in 1880 on $10,000 of seed money from the American inventor Thomas Edison, Science has grown to become the world's leading outlet for scientific news, commentary, and cutting-edge research, with the largest paid circulation of any peer-reviewed general-science journal. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. In content, too, the journal is truly international in scope; some 35 percent to 40 percent of the corresponding authors on its papers are based outside the United States. Its articles consistently rank among world's most cited research.

About Stevens Institute of Technology

Founded in 1870, Stevens Institute of Technology is one of the leading technological universities in the world dedicated to learning and research. Through its broad-based curricula, nurturing of creative inventiveness, and cross disciplinary research, the Institute is at the forefront of global challenges in engineering, science, and technology management. Partnerships and collaboration between, and among, business, industry, government and other universities contribute to the enriched environment of the Institute. A new model for technology commercialization in academe, known as Technogenesis®, involves external partners in launching business enterprises to create broad opportunities and shared value. Stevens offers baccalaureates, master's and doctoral degrees in engineering, science, computer science and management, in addition to a baccalaureate degree in the humanities and liberal arts, and in business and technology. The university has a total enrollment of 2,150 undergraduate and 3,500 graduate students with about 250 full-time faculty. Stevens' graduate programs have attracted international participation from China, India, Southeast Asia, Europe and Latin America. Additional information may be obtained from its web page at
