Deep Space Communication May Switch To Lasers

Lasers, the highly concentrated light beams once considered unsuitable for long-distance communications, may become the best way to transmit large amounts of data across deep space.Scientists at the U.S. National Institute of Standards and Technology and NASA's Jet Propulsion Laboratory say they have developed a tiny array of superconducting light sensors sensitive enough to detect the smallest particle of light - a single photon. Even more, the chip can detect the position - left or...
