Quantum-entangled light from a vibrating membrane

Entanglement, a powerful form of correlation among quantum systems, is an important resource for quantum computing. Researchers from the Quantum Optomechanics group at the Niels Bohr Institute, University of Copenhagen, recently entangled two laser beams through bouncing them off the same mechanical resonator, a tensioned membrane. This provides a novel way of entangling disparate electromagnetic fields, from microwave radiation to optical…

The US Army Wants To Microwave Drones in Midair

“The U.S. Army, as part of a broad counter-unmanned aerial systems strategy, is pushing forward with the U.S. Air Force to develop a high-powered microwave weapon,” reports Popular Mechanics: Microwave radiation can disrupt or destroy electronic equipment exposed to them, “cooking” internal circuits much in the same way a fork or other metal objects placed in a microwave oven will cause…
