Talk Title: "The Story of Stopped Light"
Recent experiments have shown that a pulse of light can
be brought to a stop in a specially-prepared cloud of
atoms, and then re-accelerated and released on command.
This talk will describe how "stopped light"
is a new manifestation of the rules of quantum mechanics,
with potential applications to optical communication networks,
including ultra-secure quantum communication.
Dr. Ronald Walsworth is a Senior Lecturer on Physics at Harvard
University and a Senior Scientist at the Smithsonian Institution. He
leads a research group pursuing a wide range of investigations,
including the development of atomic clocks; precise tests of
fundamental physical laws and symmetries; "stopped light" and
applications to quantum information processing; studies of porous and
granular media; and biomedical imaging with applications to pulmonary
physiology and medicine. His research has been featured in media such
as the New York Times, Boston Globe, National Public Radio,
Scientific American, Physics Today, and Discover Magazine.
