Researchers use quantum entanglement to improve differential interference contrast microscopy

(Phys.org)—A team of researchers with members from Hokkaido and Osaka Universities in Japan has used quantum entanglement of photons to improve image results created using differential interference contrast microscopy. In their paper published in Nature Communications, the team describes how they used entangled photons to enhance an image taken of an etched (to a depth of just 17 nanometers) letter “Q” on a glass plate, and how much improvement was observed.
