An anonymous reader writes "ZDNet Aus reported on a new low noise chip which could help to building the 1.8 billion dollar Square Kilometer Array (SKA), the world's largest radio telescope. Wikipedia claims the telescope will be 50 times as sensitive as current instruments. It will have a resolution of able to detect every active galactic nucleus (AGN) out to a redshift of 6, when the universe was less than 1 billion years old and way crazy. It will have the sensitivity to detect Earth-like radio leakage at a distance of several hundred to a few thousand light years, which will help greatly with the search for extraterrestrial life.
Quoting the Story:
Prof. Jack Singh who designed the chip said: 'The big challenge [was] to overcome the inherent noise in an integrated circuit, and to produce an amplifier with the lowest noise possible, with broad frequency band and high gain.' He also commented on the chip's ability to help with Quantum Computer research, due to its ability to operate at millikelvin temperatures, necessary to prevent quantum decoherence."
