- How can the QR code be viewed and used?
- The tiny QR code is not visible to the naked eye and cannot be scanned with a smartphone; a microscope is needed to view and enlarge it. The current application is limited to showcasing the university's nanotechnology capabilities.
- What technology was used to create the QR code?
- The QR code was created using electron beam lithography at the Münster Nanofabrication Facility. This advanced technology allowed for the creation of such a tiny code, which is currently only used to direct to the university's quantum physics department website.
- What are the potential future applications of this technology?
- While the current application is limited, the creation of this minuscule QR code demonstrates the advancements in nanotechnology and the potential for future applications, such as advanced data storage or microscopic labeling.
- What is the size of the world's smallest QR code and who created it?
- The world's smallest QR code, measuring 5.38 square micrometers, has been created by German students at the University of Münster. It's about 20 times smaller than the previous record holder and smaller than a human red blood cell.
- Who were the individuals and organizations involved in creating and verifying the QR code?
- The team behind the record-breaking QR code consisted of a student and two PhD candidates from the University of Münster's quantum technology department, under the supervision of Professor Carsten Schuck. The achievement has been independently verified by Hitachi High-Tech Europe GmbH.
