Researchers create orientation-independent magnetic field-sensing nanotube spin qubits

(Funded by the National Science Foundation)
Purdue University researchers have developed patent-pending one-dimensional boron nitride nanotubes containing spin qubits, or spin defects. These nanotubes are more sensitive in detecting off-axis magnetic fields at high resolution than traditional diamond tips used in scanning probe magnetic-field microscopes. Applications include quantum-sensing technology that measures changes in magnetic fields and collects and analyzes data at the atomic level.
