- Abstract summary: Hexagonal boron nitride exhibits two types of defects with great potential for quantum information technologies.
A single SPE can be used to induce single-, two- and qubit-phonon states in the one dimensional channel.
Two distant SPEs can be coupled by the TPL that acts as a waveguide, thus exhibiting strong quantum correlations.

- Abstract: Hexagonal 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 as {\it{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 \textit{(ii)} two distant SPEs can
be coupled by the TPL that acts as a waveguide, thus exhibiting strong quantum
correlations. We highlight the possibilities offered by this material-built-in
nano-architecture as a phononic device for quantum information technologies.
