In a paper recently published by the Physics Review, Shimon Kolkowitz and team explain how an atomic clock can be improved by splitting it up

Thanks to their remarkable precision and accuracy, optical atomic clocks are rapidly advancing the frontiers of timekeeping...

QUANT-NET consortium seeks to establish a distributed quantum computing network

January 8, 2024

Members of Quant-Net

QUANT-NET researchers Erhan Saglamyurek, Hartmut Häffner, Inder Monga and Wenji Wu demonstrate their ion-trap quantum processor, a key subsystem in the network testbed connecting Häffner’s UC Berkeley physics lab to Berkeley Lab.

Today’s internet distributes classical bits and bytes of information over global, even interstellar, distances. The quantum internet of tomorrow, on the other hand...

Dan Stamper-Kurn

Professor

Dan M. Stamper-Kurn came to Berkeley following his studies at the Massachusetts Institute of Technology (Ph.D. 2000) and postdoctoral work at the California Institute of Technology (1999 – 2001). He is the recipient of the 2000 APS Division of Atomic, Optical and Molecular Physics Outstanding Thesis award, the Alfred P. Sloan Fellowship (2001 – 2003), the David and Lucile Packard Fellowship in Science and Engineering (2002 – 2007), and the Presidential Young Investigator Award in Science and Engineering (2002). He holds the Class of 1936 Second Chair in the College of Letters and Sciences...

Feng Wang

Professor

Feng Wang received a B.A. from Fudan University, Shanghai, in 1999 and a Ph.D. from Columbia University in 2004. From 2005-2007, he has been a Miller Fellow with Miller Institute for Basic Science at Berkeley. He joined the physics faculty in fall, 2007.

Research Interests

We are interested in light-matter interaction in condensed matter physics, with an emphasis on novel physical phenomena emerging in nanoscale structures and at surfaces/interfaces. When electrons and phonons are confined in nanometer scale or at surface/interfaces, they respond differently to external stimuli. We...

Matt C. Pyle

Assistant Professor, Michael M. Garland Chair

Matt Pyle received B.S. in Physics (2001) and B.E. in Aerospace Engineering (2002) from the University of Notre Dame, and a Ph.D. in Physics from Stanford University (2012). Subsequently, he crossed the bay and was a postdoctoral researcher at Berkeley. He joined the Berkeley Physics faculty as the Garland Assistant Professor in 2015.

Research Interests

Many of the questions that we would like to ask about the nature of the universe today, for example "could dark matter be composed of particles with mass less than that of a proton?", are simply impossible to answer with present...

Stephen Leone

The John R. Thomas Professor in Physics

Dr. Leone received his B.A. in Chemistry at Northwestern University in 1970 and his Ph.D. in Chemistry at the University of California at Berkeley with Professor C. Bradley Moore in 1974. He was an assistant professor at the University of Southern California from 1974-76. He assumed a position with NIST and the University of Colorado in 1976 and became a full professor in 1982. Dr. Leone was a Fellow and staff member of the National Institute of Standards and Technology, a Fellow of JILA, as well as an Adjoint Professor of Chemistry and Biochemistry and a Lecturer of Physics at the...

Eric Y. Ma

Assistant Professor

Eric Y. Ma received his B.S. in Physics from Peking University in 2010 and his Ph.D. in Applied Physics from Stanford University in 2016. He stayed at Stanford as a joint postdoctoral scholar in Applied Physics and Electrical Engineering. He was also briefly Senior Scientist at Apple. In July 2021 Dr. Ma joined UC Berkeley full-time as Assistant Professor in Physics and by courtesy EECS, and currently holds the Georgia Lee Chair in Physics.

Research Interests

Most practical phenomena, except those related to nuclear reactions, can be well described by atomic nuclei and electrons...

Alessandra Lanzara

Professor, Charles Kittel Chair in Physics

Alessandra Lanzara received her PhD in physics from Universita’ di Roma La Sapienza, Italy in 1999. She was a postdoc at Stanford University for three years since 1999. In 2002 she joined the physics Department faculty at UC Berkeley as Assistant Professor and since 2011 she is a Full Professor. She is also a Senior Faculty Scientist at the Materials Sciences Division of the Lawrence Berkeley National Laboratory since 2002.

She is recipient of many prizes among which was elected Fellow of the American Physical Society in 2008 and elected to the American Academy of Art and Science in...

Hartmut Haeffner

Professor

Hartmut Häffner received his PhD in physics from the University of Mainz / Germany in 2000. After short periods as a Postdoctoral fellow in Mainz and Bangalore/India, he received a Feodor-Lynen fellowship from the Alexander-von-Humboldt foundation Germany and went to NIST / Gaithersburg as a guest researcher (2000-2001). In 2001 he moved to the University of Innsbruck / Austria as a university assistant where he held a Marie-Curie fellowship from the European Union from 2002 - 2004. From 2004 till 2009 he worked as senior scientist at the Institute for Quantum Optics and Quantum...
