Stretching Diamonds Unlocks Powerful New Quantum Sensing Abilities

Researchers showed that stretching or compressing diamond can predictably tune silicon-vacancy defects.

Computational modeling found changes in the defects’ atomic structure, optical response, and magnetic behavior under strain.

A major structural transition appears beyond about 4% tensile strain.

The results could enable strain-controlled quantum sensors for precise measurement of pressure, temperature, and deformation in harsh nanoscale environments.
