- Abstract summary: We develop a parallel optically detected magnetic resonance (PODMR) spectrometer to address, manipulate and read out an array of single nitrogen-vacancy (NV) centers in diamond in parallel.
In this spectrometer, we use an array of micro-lens to generate 20 * 20 laser-spot lattice (LSL) on the objective focal plane, and then align the LSL with an array of single NV centers.
The quantum states of NV centers are manipulated by a uniform microwave field from a Omega-shape coplanar coil.

- Abstract: We develop a parallel optically detected magnetic resonance (PODMR)
spectrometer to address, manipulate and read out an array of single
nitrogen-vacancy (NV) centers in diamond in parallel. In this spectrometer, we
use an array of micro-lens to generate 20 * 20 laser-spot lattice (LSL) on the
objective focal plane, and then align the LSL with an array of single NV
centers. The quantum states of NV centers are manipulated by a uniform
microwave field from a {\Omega}-shape coplanar coil. As an experimental
demonstration, we observe 80 NV centers in the field of view. Among them,
magnetic resonance (MR) spectrums and Rabi oscillations of 18 NV centers along
the external magnetic field are measured in parallel. These results can be
directly used to realize parallel quantum sensing and multiple times speedup
compared with the confocal technique. Regarding the nanoscale MR technique,
PODMR will be crucial for high throughput single molecular MR spectrum and
imaging.

Microwave or radio-frequency driving poses a significant limitation for miniaturization, energy-efficiency and non-invasiveness of quantum sensors.
We overcome this limitation by demonstrating a purely optical approach to coherent quantum sensing.

The nitrogen-vacancy (NV) center is one of the most interesting to be used as a platform for quantum technologies and nanosensing.
Traditionally, synthetic diamond is irradiated with high-energy electrons or nitrogen ions to generate these color-centers.
For precise positioning of the NV centers, fs-laser irradiation has been proposed as an alternative approach to produce spatially localized NV centers in diamond.
