What is it about?
Defects in hexagonal boron nitride may host single-photon emitters, a crucial component for quantum networks. We have shown for the first time that these defects can be transferred, like legos, onto different structures without losing their unique single-photon emission.

Why is it important?
Our findings show that the van der Waals material, hexagonal boron nitride, remains intact through a lego-type transfer process onto other surfaces. This process maintains the single-photon purity, and other unique photonic properties such as the radiative lifetime, stability of the emitter, and spectral line shape. This may lead to further discoveries combining these photonic properties with exotic or unique properties of other electronic, magnetic, or plasmonic materials.
Perspectives
I hope that this article gives some insights into the materials that may gather interest for quantum applications. Two-dimensional van der Waals materials have offered unique properties from 3D bulk crystals that have advanced science in electronics, optics, and magnetism like flexible electronics, high-speed devices, low-energy consumption technology, and more. The study of materials at the atomic scale opens up a wide variety of possibilities to discover in science and engineering
