Researchers in the Computational Materials Group at the University of California, Santa Barbara (UCSB) have uncovered the fundamental limits on optical transparency in the class of materials known as transparent conducting oxides. Their discovery will support development of energy efficiency improvements for devices that depend on optoelectronic technology, such as light- emitting diodes and solar cells.

A team of physicists headed by Prof.

(PhysOrg.com) -- Taking another step toward demonstrating quantum behavior in a quantum computer, researchers from the Vancouver-based company D-Wave Systems, Inc., have performed a technique called quantum annealing, which could provide the computational model for a quantum processor.
