A team of physicists from the University of Münster in Germany has created the smallest quick response (QR) code in the world, earning them a place in the Guinness World Records. The QR code measures 5.38 square millimeters in size, which is smaller by about 20 times than the previous world record held by a research team in Singapore, and about 7 times smaller than a human red blood cell. The QR code is too small to be seen with the naked eye, but it can be magnified several times on a computer screen using a microscope. The code is linked to the university's website on quantum physics and was recognized as a record by Guinness World Records after independent measurements were conducted by a technology company. The university plans to use this record to promote the study of physics.
