Folded 2D materials have properties useful for quantum
communications

Graphene is a material made of carbon atoms one layer
thick, arranged in a honeycomb structure. It has been used to make
materials stronger, create ultra-high frequency components for
communications, boost battery performance and even used to make
COVID-19 tests. It’s the archetypal two-dimensional (2D)
material—but there’s much more to 2D materials than
graphene.
