They are the ultimate unknown – the blackest and most dense objects in the universe that do not even let light escape.

However, to achieve the same kind of interaction with sound waves has been a more challenging undertaking.
The researchers at the Chalmers University of Technology in Sweden have now succeeded in making acoustic waves couple to an artificial atom.
"We have opened a new door into the quantum world by talking and listening to atoms," said Per Delsing, head of the experimental research group.
