Donald N. Langenberg, 1932-2019

Donald N. Langenberg, a physicist who served as the Chancellor of the University System of Maryland from 1990-2002, died January 25, 2019, at his home in Baltimore.  He was 86.
 
After receiving his Ph.D. at the University of California, Berkeley, Langenberg researched low temperature solid state physics at the Laboratory for Research on the Structure of Matter at the University of Pennsylvania. In 1972 he became the lab's director, and subsequently held a number of senior administrative positions at Penn. He was the Deputy Director of the National Science Foundation from 1980-82, then Chancellor of the University of Illinois, Chicago, where he oversaw the merger of two large and distinct entities. From there, he was selected to oversee the 11-campus University System of Maryland, which had been reorganized just two years earlier. 
 
Langenberg had a deep commitment to education. He was born in rural North Dakota to deaf parents, and left home as a toddler to stay with his grandparents in Iowa, learn English and start school. He later returned to North Dakota, where he graduated from high school before entering Iowa State University for an undegraduate degree in physics. 
 
After retiring as USM Chancellor, he remained very active, chairing the Committee on Undergraduate Physics Education Research and Implementation of the National Academies of Science and serving on the National Research Council's Committee on the Study of Teacher Preparation Programs in the United States. Other roles included work as the Vice-Chair of the National Council for Science and the Environment and on the Board of Trustees of the University of the District of Columbia. Langenberg served as President of the American Physical Society in 1993.
 

Norbert M. Linke Joins UMD Physics

Norbert M. Linke has joined the Department of Physics as an assistant professor. He has been a member of the department since 2015, first as a post-doc and then as a research scientist at the Joint Quantum Institute. Working in the group of Chris Monroe, he led a project that turned a physics experiment into a programmable quantum computer. This work helped establish trapped atomic ions as a leading contender in the quantum computing realm, and produced the first cross-platform comparison of two quantum computers in 2017

Linke was born in Munich, Germany,  and graduated from the University of Ulm, Germany. He received his doctorate at the University of Oxford, UK, working on micro-fabricated ion-traps, high-fidelity quantum gates, and microwave-addressing of ions under David Lucas. 

His new group at UMD continues to work on quantum applications with trapped ions, implementing more sophisticated algorithms, but also expanding to simulations of new and unusual quantum dynamics involving the ions' motional degrees of freedom. Additionally, his lab has launched a new project to realize long-distance quantum communication using trapped ions and near-telecom photons.

Weber Garden Dedication Held March 12

WeberMemorialNews12919 2The Department of Physics and College of Mathematical and Natural Sciences held a dedication of the Weber Garden on Tuesday, March 12, 2019, which included remarks by colleagues and friends of Joe Weber and a colloquium by Nobel Laureate Rai Weiss: What Joe Weber started: Gravitational wave astronomy. 
 
The garden, next to the main entrance of the Physical Sciences Complex, highlights the ultrapure aluminum gravity bars of UMD physicist Joseph Weber, a pioneer in the search for gravitational waves. Prof. Emeritus Charles W. Misner and his wife Susanne established the Weber Endowment for Gravitational Physics
 
The 2016 announcement that the LIGO experiment had detected gravitational waves led to the Nobel Prize for Weiss, Kip Thorne and Barry Barish.  UMD's key contributions in theoretical and experimental gravitational physics were discussed at a Nov. 1, 2016 symposium, A Celebration of Gravitational Waves.

Christopher Monroe Quoted in Gizmodo Article on IBM's New Quantum Computer

Distinguished University Professor & Bice Seci-Zorn Professor Christopher Monroe was quoted in the Gizmodo article, "Why Experts Are Skeptical of IBM's New Commercial Quantum Computer," which explores "Q System One, or as the IBM team described it, “the world’s first fully integrated universal quantum computing system designed for scientific and commercial use.”"
