The researcher further adds that their work bridges quantum and optical data storage, meeting the need for better quantum systems and improved classical memory storage. The research began during França’s Ph.D. studies at the University of São Paulo in Brazil, where he focused on radiation dosimeters – devices that passively monitor radiation exposure for workers in hospitals, synchrotrons, and other radiation facilities. These materials can absorb radiation and store the exposure information for a specific period.
França explained that when the crystal absorbs enough energy, it releases electrons and holes, which are then captured by the defects. This information can be read by releasing the electrons and detecting them optically. Recognizing its potential for memory storage, França brought this non-quantum approach to Zhong’s quantum laboratory, leading to the interdisciplinary innovation.
