Time Crystals on Money?! Future of Cryptography is Here!

Physicists at the University of Colorado Boulder have created the first visible time crystal using liquid crystals that swirl into never-ending patterns when illuminated by light, operating at room temperature and visible to the naked eye; this breakthrough enables revolutionary applications in cryptography and anti-counterfeiting, including dynamic QR codes that change periodically (e.g., 2-second, 3-second, and 5-second cycles) and unforgeable signatures on currency that can be verified by shining a flashlight, representing a transition from theoretical quantum systems to practical macroscopic engineering applications.
