Few terms are more ubiquitous in the scientific arena these days than "quantum."
Technologies based on the notoriously tricky laws of quantum mechanics promise to enable computers much more powerful than today's fastest supercomputers, unhackable secure communications and unprecedented sensing capabilities necessary for further scientific discovery.
But for these technologies to see the light of day, researchers must develop efficient quantum communications networks that connect quantum devices while preserving the delicate states of the particles used to transmit information.
A team of researchers at the Department of Energy's Oak Ridge National Laboratory, along with colleagues at Purdue University, has taken an important step toward this goal by harnessing the frequency, or color, of light. Such capabilities could contribute to more practical and large-scale quantum networks exponentially more powerful and secure than the classical networks we have today.
