Two interesting findings from physicists in China:

Diamond data storage: At below 100 degrees Kelvin, a common diamond defect, the nitrogen-vacancy (NV) center (a nitrogen atom impurity paired with a “hole” where a carbon atom is absent from the matrix structure) could be used to store information because of the predictable way in which electrons confined in the center interact with electromagnetic waves.

Entropic uncertainty principle: An optical experiment to test the entropic uncertainty principle suggests that quantum entanglement may help reduce uncertainty to zero.
