Integrating optics and electronics into systems such as fiber-optic data links has revolutionized how we transmit information. A second revolution awaits as researchers seek to develop chips in which individual atoms control the movement of light within the chip through optical "wires," and photons could replace electrons as the vehicle for performing computations. Andrei Faraon (BS '04), an assistant professor of applied physics and materials science in the Division of Engineering and Applied Science, presents a preview of this revolution at 8 p.m. on Wednesday, December 17, in Caltech's Beckman Auditorium. Admission is free.

Researchers have set a new world record for data transfer, helping to usher in the next generation of high-speed network technology. The international team was able to transfer data in opposite directions at a combined rate of 186 gigabits per second (Gbps) in a wide-area network circuit. The rate is equivalent to moving two million gigabytes per day, fast enough to transfer nearly 100,000 full Blu-ray disks—each with a complete movie and all the extras—in a day.

Caltech has been awarded $12.6 million in funding over the next five years by the National Science Foundation to create a new Physics Frontiers Center. Dubbed the Institute for Quantum Information and Matter (IQIM), the center will bring physicists and computer scientists together to push theoretical and experimental boundaries in the study of exotic quantum states.

For the first time, researchers at Caltech, in collaboration with a team from the University of Vienna, have managed to cool a miniature mechanical object to its lowest possible energy state using laser light. The achievement paves the way for the development of exquisitely sensitive detectors as well as for quantum experiments that scientists have long dreamed of conducting.

Caltech researchers, led by William L. Valentine Professor and professor of physics H. Jeff Kimble, have made an important achievement in the field of quantum information. Their proof-of-principle experiment, in which they demonstrate quantum entanglement with a four-part system, helps pave the way toward quantum networks and quantum computers, machines much faster than conventional, silicon-based ones.

Researchers at the Caltech have proposed a new paradigm that should allow scientists to observe quantum behavior in small mechanical systems. Their ideas, described in the early online issue of the Proceedings of the National Academy of Sciences, offer a new means of addressing one of the most fascinating issues in quantum mechanics: the nature of quantum superposition and entanglement in progressively larger and more complex systems.

Scientists at Caltech have developed an efficient method to detect entanglement shared among multiple parts of an optical system. They show how entanglement, in the form of beams of light simultaneously propagating along four distinct paths, can be detected with a surprisingly small number of measurements. Entanglement is an essential resource in quantum information science, which is the study of advanced computation and communication based on the laws of quantum mechanics.

Building on seven years of record-breaking developments, an international team of physicists, computer scientists, and network engineers led by the California Institute of Technology (Caltech)--with partners from Michigan, Florida, Tennessee, Fermilab, Brookhaven, CERN, Brazil, Pakistan, Korea, and Estonia--set new records for sustained data transfer among storage systems during the SuperComputing 2008 (SC08) conference recently held in Austin, Texas. Caltech's exhibit at SC08 by the High Energy Physics (HEP) group and the Center for Advanced Computing Research (CACR) demonstrated new applications and systems for globally distributed data analysis for the Large Hadron Collider (LHC) at CERN, along with Caltech's global monitoring system MonALISA (http://monalisa.caltech.edu) and its collaboration system EVO (Enabling Virtual Organizations; http://evo.caltech.edu), together with near real-time simulations of earthquakes in the Southern California region, experiences in time-domain astronomy with Google Sky, and recent results in multiphysics multiscale modeling.

Scientists at the California Institute of Technology have laid the groundwork for a crucial step in quantum information science. They show how entanglement, an essential property of quantum mechanics, can be generated between beams of light, stored in a quantum memory, and mapped back into light with the push of a button.
