Scientists have identified a method to create multiple copies of quantum information by encrypting them with a one-time decryption key, sidestepping the no-cloning theorem. This approach, developed by Achim Kempf and colleagues at the University of Waterloo, was tested on an IBM quantum processor. The technique could enhance redundancy in quantum computing and storage systems.
