Entanglement beats the diffraction limit
PhysicsWeb - Entanglement beats the diffraction limit: "Physicists have succeeded in 'entangling' more than two photons for the first time. A Canadian team has entangled three photons while an Austrian team have created a four-photon entangled state. The wavelengths of the entangled states are three and four times shorter than the original wavelengths of the photons. By overcoming the so-called diffraction limit, entangled photons could prove useful in a range of applications ranging from lithography to microscopy."
