(Image: Andreas Gottscholl / Universität Würzburg) A new type of atomic sensor made of boron nitride is presented by researchers in "Nature Communications". The sensor is based on a qubit in the crystal lattice and is superior to comparable sensors. An artificially created spin defect (qubit) in a crystal lattice of boron nitride is suitable as a sensor enabling the measurement of different changes in its local environment. The qubit is a boron vacancy located in a two-dimensional layer of hexagonal boron nitride and has an angular momentum (spin). The defect is very sensitively to its atomic environment, for example to the distances to other atoms or atomic layers. "This allows local measurements of magnetic fields, temperature and even pressure," says Professor Vladimir Dyakonov, head of the Chair of Experimental Physics VI at Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany.
