“…By observing the atoms' absorption profile, and specifically its Fourier decomposition, we can deduce the alignment of the magnetic field in three dimensions. Similar to other recent work [38,39], our scheme requires only a single probe beam, thereby avoiding potential transverse dephasing effects. Unlike these previous schemes, the sim-ple F = 1 → F = 0 configuration allows us to decouple the effect of 3D alignment from a modification of the magnetic field strength: demonstrating an atomic compass based on the absorption profile of a vector vortex beam.…”

We describe and demonstrate how 3D magnetic field alignment can be inferred from single absorption images of an atomic cloud. While optically pumped magnetometers conventionally rely on temporal measurement of the Larmor precession of atomic dipoles, here a cold atomic vapour provides a spatial interface between vector light and external magnetic fields. Using a vector vortex beam, we inscribe structured atomic spin polarisation in a cloud of cold rubidium atoms, and record images of the resulting absorption patterns. The polar angle of an external magnetic field can be deduced with spatial Fourier analysis. This effect presents an alternative concept for detecting magnetic vector fields, and demonstrates, more generally, how introducing spatial phases between atomic energy levels can translate transient effects to the spatial domain.

We describe and demonstrate how 3D magnetic field alignment can be inferred from single-shot absorption images of an atomic cloud. While optically pumped magnetometers conventionally rely on temporal measurement of the Larmor precession of atomic dipoles, here cold atomic vapours provide a spatial interface between vector light and external magnetic fields. Using a vector vortex beam, we inscribe structured atomic spin polarisation in a cloud of cold rubidium atoms, and record images of the resulting absorption patterns. The spherical alignment can be deduced with spatial Fourier analysis. This effect not only raises the prospect of a conceptually new approach to detecting magnetic fields, but, more generally, demonstrates how introducing spatial phases between atomic energy levels can translate transient effects to the spatial domain.

“…With the development of quantum information science, various quantum systems have widely potential applications in the rapidly emerging research fields like quantum computation [1][2][3][4][5], quantum simulation [6][7][8][9][10], and quantum metrology [11][12][13][14]. In particular, the nitrogen-vacancy (NV) centers in diamond work as excellent quantum sensors for magnetic fields [15,16], electric fields [17], and temperatures [18]. With the assistance of optically detected magnetic resonance (ODMR) technique, manipulation and detection of NV centers can be easily realized by utilizing laser pumping and resonant alternating magnetic fields [19], where the spin-state-dependent fluorescence can be collected by suitable detectors depending on its intensity.…”

We report a mixed-signal data acquisition (DAQ) system for optically detected magnetic resonance (ODMR) of solid-state spins. This system is designed and implemented based on a Field-Programmable-Gate-Array (FPGA) chip assisted with high-speed peripherals. The ODMR experiments often require high-speed mixedsignal data acquisition and processing for general and specific tasks. To this end, we realized a mixed-signal DAQ system which can acquire both analog and digital signals with precise hardware synchronization. The system consist of 4 analog channels (2 inputs and 2 outputs) and 16 optional digital channels works at up to 125 MHz clock rate. With this system, we performed general-purpose ODMR and advanced Lock-in detection experiments of nitrogen-vacancy (NV) centers, and the reported DAQ system shows excellent performance in both single and ensemble spin cases. This work provides a uniform DAQ solution for NV center quantum control system and could be easily extended to other spin-based systems.
