[0]KentuckyFC writes “An international team of physicists has applied the
ideas of cloaking to the quantum world and [1]worked out how to hide
quantum objects such as molecules. In the quantum world, seeing is
equivalent to detecting a quantum object. In the case of molecules, that
means looking for the terahertz radiation they produce when they vibrate
([2]abstract). By designing a ‘quantum corral,’ an elliptical
nanostructures that absorbs terahertz waves at a precise frequency, the
team says it is possible to hide molecules that emit at exactly that
frequency. They say their quantum corral would be ideally suited to
detecting molecules of specific species while ignoring others. And that
may mean a new generation of molecular detectors on the horizon.”
