A diamond quantum sensor is used to determine the magnetic properties of individual atomic layers of the material chromium triiodide in a quantitative manner. It was shown that the direction of the spins in successive layers alternate in the layers. (University of Basel, Department of Physics)

Unprecedented insight into two-dimensional magnets

The discovery of ferromagnetism in 2D van der Waals (vdW) crystals has generated widespread interest. Making further progress requires quantitative knowledge of the magnetic...
Researchers from MIT and elsewhere have recorded the “temporal coherence” of a graphene qubit — how long it maintains a special state that lets it represent two logical states simultaneously — marking a critical step forward for practical quantum computing

Physicists record lifetime of graphene qubits

For the first ever time, MIT scientists have quantified the temporal coherence (lifetime) of graphene qubits- meaning to what extent it can keep up a...
