Breakthrough in 2D Quantum Sensors Unlocks Advanced Magnetic Field Detection
Scientists at the University of Cambridge have developed a next-generation 2D quantum sensor that detects vectorial magnetic fields with unprecedented accuracy. By leveraging atomic spin defects in hexagonal boron nitride (hBN), this innovation surpasses traditional diamond-based quantum sensors, offering multi-axis detection and enhanced sensitivity at the nanoscale. How Hexagonal Boron Nitride Transforms Quantum Sensing Hexagonal boron nitride, a two-dimensional material similar to graphene, possesses unique quantum properties that make it ideal for sensing applications. Unlike conventional quantum sensors relying on nitrogen vacancy centers in diamond, hBN-based sensors provide multi-axis magnetic field detection, enabling researchers to measure directional variations with superior precision. Atomic-scale defects within hBN absorb and emit visible light in response to local magnetic conditions, allowing real-time monitoring of quantum interactions. Advancements in Nanosc...
