Welcome

The Institute for Quantum Information and Matter (IQIM) at Caltech is a Physics Frontiers Center supported by the National Science Foundation and the Gordon and Betty Moore Foundation. IQIM researchers study physical systems in which the weirdness of the quantum world becomes manifest on macroscopic scales. Our research programs span quantum information science, quantum condensed matter physics, quantum optics, and the quantum mechanics of mechanical systems.

Kerry VahalaResearchers in the laboratory of Kerry Vahala, Ted and Ginger Jenkins Professor of Information Science and Technology and Applied Physics; Executive Officer for Applied Physics and Materials Science, have developed a method to stabilize microwave signals in the range of gigahertz, or billions of cycles per second—using a pair of laser beams as the reference, in lieu of a crystal.

Quartz crystals "tune" oscillators by vibrating at relatively low frequencies—those that fall at or below the range of megahertz, or millions of cycles per second, like radio waves. However, quartz crystals are so good at tuning these low frequencies that years ago, researchers were able to apply a technique called electrical frequency division that could convert higher-frequency microwave signals into lower-frequency signals, and then stabilize these with quartz.
