Findings help pave way for next generation of computer chips Stretching for thousands of miles beneath oceans, optical fibers now connect every continent except for Antarctica. With less data loss and higher bandwidth, optical-fiber technology allows information to zip around the world, bringing pictures, video, and other data from every corner of the globe to your computer in a split second. But although optical fibers are increasingly replacing copper wires, carrying information via photons...

Milestone reached on the path to integrated quantum technology Quantum information processing is arguably one of the most fascinating facets of modern quantum physics. A quantum computer operates with quantum bits (qubits) as units of information. Obeying the laws of quantum mechanics, such a computer would be capable of addressing several of the most difficult computational tasks unsolvable with present technology. In the past few decades, scientists learned to perform room-sized experiments...
