U.S. Defense Looks To Quantum Radar

The US military is taking its war on terror where even Albert Einstein feared to tread - into the baffling world of quantum mechanics. Lockheed Martin, a main US defense contractor, thinks it can exploit research on the fringes of theoretical physics to build the ultimate radar, which could see through anything, from buildings to solid earth. The company has designed and patented a scanner based on the principle of quantum entanglement - a far out concept, even by the weird standards of the quantum world. It says the device could penetrate any type of defence, to identify hidden weapons and roadside bombs from hundreds of miles away. Quantum entanglement says that two particles can be joined so that whatever happens to one must also happen to its partner, however far apart they are. Einstein called it "spooky action at a distance". Lockheed Martin prefers: "Quantum radar is capable of providing information about targets that cannot be provided using classical radar systems."
