Human Cardiac Measurements with Diamond Magnetometers
Muhib Omar, Magnus Benke, Shaowen Zhang +27
We demonstrate direct, non-invasive and non-contact detection of human cardiac magnetic signals using quantum sensors based on nitrogen-vacancy (NV) centers in diamond. Three confi…
Zero- to low-field J-spectroscopy with a diamond magnetometer
Muhib Omar, Jingyan Xu, Raphael Kircher +8
We report measurements of zero- to ultra-low-field nuclear magnetic resonance (ZULF NMR) signals at frequencies of a few hertz with a diamond-based magnetic sensor. The sensing dia…
Towards high-sensitivity magnetometry with nitrogen vacancy centers in diamond using the singlet infrared absorption
Ali Tayefeh Younesi, Muhib Omar, Arne Wickenbrock +2
The negatively-charged nitrogen vacancy (NV) center in diamond is widely used for quantum sensing since the sensitivity of the spin triplet in the electronic ground state to…
Microwave-free wide-field magnetometry using nitrogen-vacancy centers
Joseph Shaji Rebeirro, Muhib Omar, Till Lenz +4
A wide-field magnetometer utilizing nitrogen-vacancy (NV) centers in diamond that does not require microwaves is demonstrated. It is designed for applications where microwaves need…
Diamond-optic enhanced photon collection efficiency for sensing with nitrogen-vacancy centers
Muhib Omar, Andreas Conta, Andreas Westerhoff +4
We present a design to increase the amount of collected fluorescence emitted by nitrogen-vacancy color centers in diamond used for quantum-sensing. An improvement was measured in c…
Near zero-field microwave-free magnetometry with ensembles of nitrogen-vacancy centers in diamond
Omkar Dhungel, Till Lenz, Muhib Omar +8
We study cross-relaxation features near zero magnetic field with ensembles of nitrogen-vacancy (NV) centers in diamond and examine their properties in samples with a range (0.9 ppm…
Fiberized diamond-based vector magnetometers
Georgios Chatzidrosos, Joseph Shaji Rebeirro, Huijie Zheng +10
We present two fiberized vector magnetic-field sensors, based on nitrogen-vacancy (NV) centers in diamond. The sensors feature sub-nT/ magnetic sensitivity. We…
