Revealing and reducing growth-induced interfacial disorder in preferentially aligned nitrogen-vacancy centers in diamond
Cheng-I Ho, Marina Davydova, Patrik Straňák +6
Nitrogen-vacancy (NV) centers in chemical-vapor-deposition (CVD) diamond can form preferentially oriented ensembles with high sensing performance and low densities of lattice defec…
Optically Addressable Molecular Spins at 2D Surfaces
Xuankai Zhou, Yan-Tung Kong, Cheuk Kit Cheung +18
Optically addressable spins at material surfaces have represented a long-standing ambition in quantum sensing, providing atomic resolution and quantum-limited sensitivity. However,…
Readout of a solid state spin ensemble at the projection noise limit
Rouven Maier, Cheng-I Ho, Andrej Denisenko +4
Spin ensembles are central to quantum science, from frequency standards and fundamental physics searches to magnetic resonance spectroscopy and quantum sensing. Their performance i…
Deformation-Driven Enhancement of Spin Defect Emission in Hexagonal Boron Nitride
Jianpei Geng, Xuankai Zhou, Nils Gross +11
The negatively charged boron vacancy (VB-) in hexagonal boron nitride (hBN) has been extensively investigated as it offers a novel playground for two-dimensional quantum sensing, w…
Efficient Detection of Statistical RF Fields at High Magnetic Field with a Quantum Sensor
Rouven Maier, Cheng-I Ho, Hitoshi Sumiya +4
Nuclear magnetic resonance (NMR) spectroscopy is widely used in fields ranging from chemistry, material science to neuroscience. Nanoscale NMR spectroscopy using Nitrogen-vacancy (…
Optical levitation of fluorescent silicon carbide nanoparticles in vacuum
Seyed Khalil Alavi, Cheng-I Ho, Iuliia Neumann +4
Levitated optomechanics is an emerging field in quantum science that explores the quantum motion of mesoscopic particles levitated in a vacuum. Expanding this approach to particles…
