Quantum Optics
Quantum Optics is the study of radiation and matter in the optical wavelength domain, where tests of fundamental physical questions are under way with unprecedented precision. The University of Rochester has been one of the world's leading centers of quantum optics from the beginning of the field in the 1960's. At present there are more than a dozen different research groups at the University involved in some aspect of quantum optics. Sophisticated probes of atoms and photons permit new insights into the foundations of quantum mechanics, with a focus on its counter-intuitive non-local character. They are also motivated by realization of futuristic applications such as quantum computing, crytography and teleportation, and exciting advances in laser cooling and trapping, recognized in the award of the 1997 Nobel Prize in Physics, which was shared by UR alumnus Steven Chu (B.S. 1970, and now US Secretary of Energy).
Departmental research in quantum optics spans a wide range of the above topics.
Prof. Agrawal's research interests are in the area of theoretical optics, particularly quantum electronics, nonlinear optics, and laser physics. His current research is focused on nonlinear silicon photonics, highly nonlinear fibers, and all-optical signal processing with semiconductor optical amplifiers.
The Cooling and Trapping (CAT) Laboratory of Prof. Bigelow is focusing on topological excitations of a spinor Bose-Einstein condensate for fundamental understanding and for application to quantum metrology and information. The CAT group also has a leading program on the formation and control of ultra-cold polar molecules. Experimental and theoretical work spans a range of studies of nonlinear atom (and molecular) optics.
Prof. Boyd is interested in studies of the nonlinear interaction of light with matter, in the use of nonlinear optics to control the group velocity of light, in the development of nanostructured materials with exotic optical properties, in the study of quantum states of light, and in the development of applications of these techniques.
Prof. Eberly's group is involved in theoretical studies of nonclassical states of radiation, continuous quantum entanglement, optical dark-state solitons, and electron correlation in high-field ionization.
Prof. Howell's interests are in experimental and theoretical studies of the foundations of quantum mechanics and in quantum information science. His studies include high transverse momentum-position and time-energy entanglement, slow and stopped light, low light level nonlinear optics and weak values.
Prof. Jordan investigates the quantum theory of dynamics and measurement in condensed matter and optical contexts. He is involved in research of electron transport and fluctuations in mesoscopic systems, many-body quantum entanglement, quantum thermodynamics, and the foundations of quantum mechanics.
Prof. Stroud's group carries out theoretical and experimental studies exploring the boundary between classical and quantum mechanics, and the ways in which the phenomena of quantum optics can lead to practical device applications.
Prof. Wolf and his research group carry out investigations chiefly in the theories of coherence and polarization of light, in inverse scattering, and are also developing a theory for determining phases of diffracted beams in X-ray crystallography.
