View MoreThe detection and modulation of single quantum states and molecular scale imaging technology are important directions in the development of precision spectroscopy instruments. With the in-depth exploration of magnetic detection technology, CIQTEK independently produced and developed a quantum diamond single spin spectrometer, based on the spectroscopic technology of nitrogen-vacancy center in diamond, which has super high magnetic detection instinct and has wide and important application prospects in different disciplines such as physics, chemistry, biology, materials, and medicine [1-11]. Development of Magnetometry Technology Spin magnetic resonance technology is by far one of the most developed and widely used conventional techniques. Magnetic detection-related spectrometers have a long history of development, and there are different methods to achieve magnetic resonance detection which have their own advantages and disadvantages. Figure 1 visualizes the distribution of several general technical means such as Hall sensors, SQUID detectors, and the spin magnetic resonance in terms of sensitivity and resolution [12]. Compared with the conventional magnetometry techniques, the diamond-based magnetic resonance method has a large improvement in both core metrics, which provides a strong reference for the development of a quantum diamond single-spin spectroscopy. Figure 1: Comparison of the indicators of various magnetometry techniques Hall sensors have been commonly used in laboratory magnetic field measurements since the 1950s. These detectors are based on the Hall effect for direct measurements of external magnetic fields [13]. When the direction of the magnetic field is different from the direction of the current in the loop, the electrons in the conductor are deflected due to the Lorentz force, and a potential difference is generated, through which the magnitude of the magnetic field is directly measured. Magnetic field probes have mainly consisted of semiconductor crystals that are able to be made into monolithic integrated circuits, which are shock resistant and easy to use but are not accurate enough. Superconducting quantum interferometer (SQUID) is a magnetic flux sensor based on Josephson junctions [14], which can measure weak magnetic signals using the variation of the voltage across the Josephson junction with the external magnetic flux in the closed loop.In the 1960s, Robert et al. successfully developed SQUID.Such magnetometry techniques have high magnetic detection sensitivity, but the instrument needs to operate in a low-temperature environment and expensive. Microscopic magnetic detection based on the diamond system is the emerging method for magnetic resonance detection. The technique combines the optical detection magnetic resonance technique (ODMR) and the point defects of nitrogen-vacancy (NV) color centers in diamond, which works by preparing NV color centers as quantum in...
