Real-time Simultaneous Dual Sensing of Temperature and Magnetic Field using NV-based Nano-diamonds
Sonia Sarkar, Namita Agrawal, Dasika Shishir +1
Quantum sensors based on Nitrogen Vacancy (NV) centers in diamond are highly capable of sensing multiple physical quantities. In this study, we use amplitude-modulated lock-in dete…
Phase-Based Approaches for Rapid Construction of Magnetic Fields in NV Magnetometry
Prabhat Anand, Ankit Khandelwal, Achanna Anil Kumar +5
With the second quantum revolution underway, quantum-enhanced sensors are moving from laboratory demonstrations to field deployments, providing enhanced and even new capabilities.…
Observation of Ultra-low AC Susceptibility in Micro-magnets Using Quantum Diamond Microscope
Dasika Shishir, Matthew L. Markham, Kasturi Saha
AC susceptometry, unlike static susceptometry, offers a deeper insight into magnetic materials. By employing AC susceptibility measurements, one can glean into crucial details rega…
Decoupling Nuclear Spins via Interaction-Induced Freezing in Nitrogen Vacancy Centers in Diamond
Abhishek Kejriwal, Dasika Shishir, Sumiran Pujari +1
Nitrogen-Vacancy (NV) centers in diamonds provide a room-temperature platform for various emerging quantum technologies, e.g. the long nuclear spin coherence times as potential qua…
Sub-second Temporal Magnetic Field Microscopy Using Quantum Defects in Diamond
Madhur Parashar, Anuj Bathla, Dasika Shishir +3
Wide field-of-view magnetic field microscopy has been realised by probing shifts in optically detected magnetic resonance (ODMR) spectrum of Nitrogen Vacancy (NV) defect centers in…
