Inventors include Garrote Contreras, Estivaliz; Terradillos Fernndez, Elena; Gonzlez Rodrguez, Marta Number; Vidal Asensio, Xavier; Lvarez Gila, Aitor; Casanova Marcos, Jorge; Munuera Javaloy, Carlos; Tobalina Novo, Ander; and Varona Uriarte, Borja.
The application for the patent was published on July 03, 2026, under issue no. 27/2026.
Abstract: A method (200) for generating a tag from a crystalline structure (102) comprising at least one defect color center (104) and a plurality of non-zero spin nuclei (106) in the vicinity of each defect color center (104), the method comprising: applying (204) at least one microwave field sequence to the crystalline structure (102); applying (206) an optical radiation to the crystalline structure (102) to excite at least one defect color center; detecting (208), for at least one defect color center (104) and at least one nuclei of the plurality of non-zero spin nuclei (106) located in the vicinity thereof, a response of the crystalline structure (102); from the detected response, determining (210), by a processor (114), an atomic signature of the crystalline structure (102), said atomic signature comprising information of the non-zero spin nuclei distribution of the at least one defect color center (104); generating (212), by the processor (114), a unique tag based on the atomic signature.
