Quantum

Quantum walks are the quantum version of classical random walks, which are a mathematical means for describing a natural random walk, e.g., simply wandering around randomly.   In a “classical random walk”, you could imagine someone starting at the centre of a city, and making a random decision at each …

China is developing a new type of spy satellite using ghost imaging technology which could spot stealth aircraft and see through smokescreens and camouflage.   Ron Meyers, quantum physicist at the Army Research Laboratory. Meyers explained ghost imaging, a technique that allows a high resolution camera to produce an image …

The first quantum revolution enabled inventions such as the laser and transistor, the basic building block of computers, when scientists knew the rules of quantum mechanics and built devices that followed those rules. The second quantum revolution is all about controlling individual quantum systems,, such as charged molecules, to a …

The US Government has now tuned to Quantum sensors to detect stealthy Russian and Chinese submarines. Quantum sensors are measuring device that takes advantage of quantum correlations, such as states in a quantum superposition or entanglement, for better sensitivity and resolution than can be obtained by classical systems. Quantum sensors …
