The exploration of innovative condensed matter physics techniques, as well as their most current innovations and N2-V magnetometry scenarios, are covered in this paper. Nitrogen-vacancy (N2-V) cores in diamond are incorporated in the N2-V magnetometry method, which allows for highly sensitive and precise measurements of magnetic fields (B). With a particular emphasis on three areas such as ferromagnetic materials/Anti ferromagnetic materials, Superconducting materials and Metals/Semiconductors. We highlight the rapidly expanding interest in employing N2-V magnetometry to investigate condensed matter physics in this study. The behavior of specific magnetic domains, domain barriers, and other nanoscale structures could be studied using the high sensitivity and spatial resolution of N2-V magnetometry. The utilization of N2-V magnetometry in numerous disciplines, including biology and materials science, are additionally explored. Future applications of N2-V magnetometry in the study of innovative condensed matter physics processes provide a wealth of fascinating possibilities which includes the creation of novel diamond materials, the integration of N2-V magnetometry with other methodologies.

Scalable and addressable integrated manipulation of qubits is crucial for practical quantum information applications. Different waveguides have been used to transport the optical and electrical driving pulses, which are usually required for qubit manipulation. However, the separated multifields may limit the compactness and efficiency of manipulation and introduce unwanted perturbation. Here, we develop a tapered fiber-nanowire-electrode hybrid structure to realize integrated optical and microwave manipulation of solid-state spins at nanoscale. Visible light and microwave driving pulses are simultaneously transported and concentrated along an Ag nanowire. Studied with spin defects in diamond, the results show that the different driving fields are aligned with high accuracy. The spatially selective spin manipulation is realized. And the frequency-scanning optically detected magnetic resonance (ODMR) of spin qubits is measured, illustrating the potential for portable quantum sensing. Our work provides a new scheme for developing compact, miniaturized quantum sensors and quantum information processing devices.

Nitrogen-vacancy centers have demonstrated significant potential as quantum magnetometers for nanoscale phenomena and sensitive field detection, attributed to their exceptional spin coherence at room temperature. However, it is challenging to achieve solid-state magnetometers that can simultaneously possess high spatial resolution and high field sensitivity. Here we demonstrate nanoscale quantum sensing with high field sensitivity by using on-chip diamond micro-ring resonators. The ring resonator enables the efficient use of photons by confining them in a nanoscale region, enabling the magnetic sensitivity of 1.0 μT/√Hz on a photonic chip with a measurement contrast of theoretical limit. We also show that the proposed on-chip approach can improve the sensitivity via efficient light extraction with photonic waveguide coupling. Our work provides a pathway toward the development of chip-scale packaged sensing devices that can detect various nanoscale physical quantities for fundamental science, chemistry, and medical applications.
