Researchers create orientation-independent magnetic field-sensing nanotube spin qubits
Tongcang Li, a professor of physics and electrical and computer engineering, leads a team that has developed the BNNTs with optically active spin qubits. "BNNT spin qubits are more sensitive to detecting off-axis magnetic fields than a diamond nitrogen-vacancy center, which is primarily sensitive to fields that are parallel to its axis, but not perpendicular," Li said. "BNNTs also are more cost-effective and offer more resilience than brittle diamond tips."
