Caltech Professor Receives German Award for Laser Innovations

H. Jeff Kimble, Valentine Professor and professor of physics at the California Institute of Technology in Pasadena, has been chosen by the private non-profit German foundation Berthold Leibinger Stiftung as the initial recipient of its new Berthold Leibinger Zukunftspreis ("Future Prize"). To be presented every two years, the prize is intended to honor "outstanding JeffKimble.jpgmilestones in research" related to laser light and carries an award of 20,000 euros (approximately $25,000). The jury recognized Kimble "for his groundbreaking experiments in the field of cavity quantum electrodynamics," which form "an essential foundation for quantum information technology...a key technology of the 21st century." Kimble's group studies the quantum mechanics of open systems, and his experiments are basic investigations of the nature of the interaction of light and matter. He said he chose cavity quantum electrodynamics as one of the few experimentally viable systems in which "the intrinsic quantum mechanical coupling dominates losses due to dissipation." Kimble is interested in transforming fundamental physical processes into scientific tools for advancing quantum information science, with applications ranging from quantum metrology to the processing and distribution of quantum information. In 1997 Kimble and his colleagues proposed and analyzed a "quantum Internet" composed of nodes capable of storing and manipulating quantum mechanical states and channels for linking the nodes together in a fully coherent fashion. The network could have nodes consisting of atoms trapped in optical cavities and channels formed by fiber-optic links carrying single-photon states. More recently his research group built a single-atom laser and observed photon blockade, where a first photon in an atom-cavity system blocks the passage of a second photon.

Glossary
electrodynamics
The study of the generation of electromagnetic power by radiation from high-energy beams.
metrology
Metrology is the science and practice of measurement. It encompasses the theoretical and practical aspects of measurement, including the development of measurement standards, techniques, and instruments, as well as the application of measurement principles in various fields. The primary objectives of metrology are to ensure accuracy, reliability, and consistency in measurements and to establish traceability to recognized standards. Metrology plays a crucial role in science, industry,...
photon
A quantum of electromagnetic energy of a single mode; i.e., a single wavelength, direction and polarization. As a unit of energy, each photon equals hn, h being Planck's constant and n, the frequency of the propagating electromagnetic wave. The momentum of the photon in the direction of propagation is hn/c, c being the speed of light.
quantum
The term quantum refers to the fundamental unit or discrete amount of a physical quantity involved in interactions at the atomic and subatomic scales. It originates from quantum theory, a branch of physics that emerged in the early 20th century to explain phenomena observed on very small scales, where classical physics fails to provide accurate explanations. In the context of quantum theory, several key concepts are associated with the term quantum: Quantum mechanics: This is the branch of...
