"quick, efficient flow of information though optical fiber to stack of several tiny diamond (some carbon atoms replaced with tin atoms) microchiplet waveguides, several being nodes controlling information flow in quantum internet... electronic qubit (electron) interacts with environment, nuclear qubit (spinning nucleus of an atom) does not, thus preserving information for long time... electron moving in diamond gets stuck at tin defect, transferring its information to spinning tin nucleus with strong interaction between both"
