Industrial manufacturing is subject to stringent testing protocols aimed at guaranteeing the quality of the final product. In some circumstances, though, these methods are not sensitive enough to detect flaws, leading to incorrect determinations of quality. Researchers at the Istituto Nazionale di Ricerca Metrologica (INRiM) in Torino, Italy have now shown that alternatives based on quantum entanglement can produce more accurate assessments of “good” and “failed” products. Importantly, the INRiM team’s system uses relatively simple equipment, increasing the chances that it could be used in industrial settings.

Physics World: Frequency upconversion makes infrared light visible
A new way of converting infrared light into visible wavelengths could make it possible to detect and measure mid-infrared signals using cheap and efficient sensors like those found in mobile-phone cameras. The method, which was developed independently by two teams of researchers, could have applications in areas as diverse as personalized medicine, environmental monitoring and security.
