Seeing the light with nist's new noiseless optical amplifier

(Phys.org) -- Most devices that amplify light suffer from the same problem: making the image brighter also adds muddying distortion. Scientists working at the National Institute of Standards and Technology have demonstrated that they can amplify weak light signals without adding noise while also carrying more information—more pixels—than other low-noise amplifiers. The new development could improve optical communications, quantum computing and information processing, and enhance biological and astronomical imaging.
