Research paperTheoreticalComputational DFTComputed PhononGeneration of phonon quantum states and quantum correlations among single photon emitters in hexagonal boron nitrideHugo Molinares, Fernanda Pinilla, Enrique Mu˜noz, Francisco Mu˜noz et al.arXiv·2024·10.1140/epjqt/s40507-024-00286-2·arXiv:2308.06244AbstractHexagonal boron nitride exhibits two types of defects with great potential for quantum information technologies: single-photon emitters (SPEs) and one-dimensional grain boundaries hosting topologically-protected phonons, termed topologically-protected phonon lines (TPL). Here, by means of a simple effective model and density functional theory calculations, we show that it is possible to use these phonons for the transmission of information. Particularly, a single SPE can be used to induce single-, two- and qubit-phonon states in the one dimensional channel, and two distant SPEs can be coupled by the TPL that acts as a waveguide, thus exhibiting strong quantum correlations.Read more
