SEMINAR: Pol Forn-Diaz [Caltech]
Cavity Quantum Electrodynamics on a chip
Feb 28, 2013 11:00 AM to Feb 28, 2013 12:00 PM atPol Forn-Diaz
Cavity quantum electrodynamics, or cavity QED, is the study of the fundamental interactions between light (photons) and matter (atoms) which take place inside an optical cavity. The first single atom experiments in cavity QED witnessed unique quantum effects which appear only when a single photon is present in the cavity. The last 20 years have seen remarkable achievements in this field, some of which were honored with the Nobel prize last October.
Atoms in optical cavities have attracted special interest as a potential platform for quantum information science. Quantum information is a modern branch of physics that employs the properties of certain quantum mechanical systems for generating, processing and transmitting special quantum states. Such states might be used to process quantum algorithms, or be stored in a quantum memory, in analogy to our conventional computers. In order to perform useful tasks, quantum information devices must be scaled up to a large number of connected components. To achieve scalability with atoms in cavities, one approach is to use tools from nanotechnology to create cavities on a patterned chip.
In this talk I will give an overview of recent progress in the field of cavity QED, including an introduction to the basic concepts of quantum information. I will then describe the quantum information experiments we conduct on cold atoms in cavities at the California Institute of Technology.
Refreshments at 10:50 AM. Seminar begins at 11:00 AM.
