Researchers analyze performance of first updatable holographic 3D display (PhysOrg.com) -- In 2008, researchers from the University of Arizona created a holographic 3D display that could write and erase images, making it the first updatable (or rewritable) holographic 3D display ever demonstrated. The key to the display was a photorefractive polymer material, which enabled the researchers to take advantage of the potential of holography to a greater extent than previously allowed. Now, in a follow-up study, the researchers have reported the results of their analysis on the performance of the display, including how the polymer enables display enhancements and what more needs to be done before such displays can be widely used. Yale scientists bring quantum optics to a microchip A report in the journal Nature describes the first experiment in which a single photon is coherently coupled to a single superconducting qubit (quantum bit or "artificial atom"). This represents a new paradigm in which quantum optics experiments can be performed in a micro-chip electrical circuit using microwaves instead of visible photons and lasers. The work is a collaboration of the laboratory of Professor Robert Schoelkopf and the theory group of Professor Steven Girvin in the Departments of Applied Physics and Physics at Yale University. Displays of the future: Smart, bendy, 3D and more Talk about gazing into the future. Imagine ultra high-definition TVs not much thicker than a millimeter. How about electronic books made with plastic screens that flex like a magazine? Or perhaps a display that lets you touch a virtual version of yourself on the other side of the glass?
