Witness the groundbreaking innovation from Purdue University as researchers unveil their latest creation – one-dimensional boron nitride nanotubes (BNNTs) housing cutting-edge spin qubits. These revolutionary BNNTs outperform conventional diamond tips in detecting off-axis magnetic fields with unparalleled precision, setting a new standard in scanning probe magnetic-field microscopes.
Leading this remarkable advancement is Tongcang Li, a distinguished professor of physics and electrical and computer engineering at Purdue University. Together with his team of brilliant minds including Xingyu Gao, Sumukh Vaidya, and Saakshi Dikshit – all graduate students at Purdue, they have published their findings in the prestigious journal Nature Communications.
“The BNNT spin qubits exhibit exceptional sensitivity to off-axis magnetic fields compared to diamond nitrogen-vacancy centers. Additionally, BNNTs offer superior cost-effectiveness and durability when compared to fragile diamond tips,” explained Li.
These BNNTs open up a realm of possibilities in quantum-sensing technology for precise measurement and analysis of magnetic field variations at the atomic level.
“Furthermore, their applications extend to industries such as semiconductors and nanoscale MRI,” added Gao.
The experimental setup involved state-of-the-art laboratory equipment including lasers, detectors, and signal generators essential for manipulating the quantum state of the nanotube spin qubits.
