As interest in quantum systems surges due to their potential applications in quantum computing, information storage, and sensing, molecular spins emerge as promising candidates for these technologies. Unlike conventional systems such as superconducting qubits and trapped ions, molecular spins offer unique advantages in stability, tunability, and scalability. However, key challenges remain in assessing their coherent properties, which are crucial for practical application. Existing techniques face limitations in terms of environmental requirements, complexity, and invasiveness. In this context, Nitrogen-Vacancy (NV) centers in diamonds emerge as a highly suitable solution, as they can operate at a wide range of temperatures and provide non-invasive optical readout. This study aims to leverage on the capabilities of NV-center-based sensors to probe the coherent properties of molecular spins, thus providing insights into their viability as stable and controllable components for future quantum technologies.
