Nanotechnology Now - Press Release: Scientists boost quantum signals while reducing noise: "Squeezing" noise over a broad frequency bandwidth in a quantum system could lead to faster and more accurate quantum measurements nanotech-now.com - get the latest breaking news, showbiz & celebrity photos, sport news & rumours, viral videos and top stories from nanotech-now.com Daily Mail and Mail on Sunday newspapers.
Researchers developed a special type of amplifier that uses a technique known as squeezing to amplify quantum signals by a factor of 100 while reducing the noise that is inherent in quantum systems by an order of magnitude. Their device is the first to demonstrate squeezing over a broad frequency bandwidth of 1.75 gigahertz, nearly two orders of magnitude higher than other architectures.
