In quantum computing, a qubit or quantum bit is the basic unit of quantum information—the quantum version of the classical binary bit physically realized with a two-state device. A qubit is a two-state (or two-level) quantum-mechanical system, one of the simplest quantum systems displaying the peculiarity of quantum mechanics. Examples …

JSTARS is a joint development project of the US Air Force and Army which provides a picture of the ground situation equivalent to that of the air situation provided by AWACS. Operating from a stand-off position often in excess of 200 km, it can detect, locate and classify tracks and …
