Caltech Physicist Named National Security Science and Engineering Faculty Fellow

Caltech's H. Jeff Kimble named National Security Science and Engineering Faculty Fellow.

Caltech Mourns the Passing of Andrew Lange

Physicist Andrew Lange passes away at the age of 52.

Caltech Astronomer Spots Second Smallest Exoplanet

Astronomers from Caltech and other institutions, using the highly sensitive 10-meter Keck I telescope atop Hawaii's Mauna Kea, have detected an extrasolar planet with a mass just four times that of Earth. The planet, which orbits its parent star HD156668 about once every four days, is the second-smallest world among the more than 400 exoplanets (planets located outside our solar system) that have been found to date.

Caltech Physicists Propose Quantum Entanglement for Motion of Microscopic Objects

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.

High Energy Physicists Set New Record for Network Data Transfer

An international team of high-energy physicists, computer scientists, and network engineers led by the California Institute of Technology (Caltech) joined forces to capture the Bandwidth Challenge award for massive data transfers during the SuperComputing 2009 (SC09) conference held in Portland, Oregon.

F. Brock Fuller, 82

F. Brock Fuller, emeritus professor of mathematics at the California Institute of Technology (Caltech), died on November 6 at the Rafael Convalescent Hospital in San Rafael, California, four years after being diagnosed with diffuse Lewy body disease. He was 82.

LIGO Listens for Gravitational Echoes of the Birth of the Universe

An investigation by the LIGO Scientific Collaboration and the Virgo Collaboration has significantly advanced our understanding of the early evolution of the universe. Analysis of data taken from 2005 to 2007 sets the most stringent limits yet on the amount of gravitational waves that could have come from the Big Bang in the gravitational wave frequency band where LIGO can observe. The results put new constraints on the details of how the universe looked in its earliest moments.

Caltech Physicists Create First Nanoscale Mass Spectrometer

Using devices millionths of a meter in size, physicists at the California Institute of Technology (Caltech) have developed a technique to determine the mass of a single molecule, in real time.

Mechanics: Nano Meets Quantum

Physicists at Caltech have developed a new tool that can be used to search for quantum effects in an ordinary object.

Uncertainty Principle Used to Detect Entanglement of Photon Shared Among Four Locations

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.
