2D Materials in Quantum Technologies: Emitters, Sensores and Photonic Applications

In this work, we address the role of two-dimensional or van der Waals materials as a versatile platform for emerging quantum technologies. We begin with a brief revision on the fundamentals of quantum mechanics and condensed matter physics, highlighting the experimental progress that enabled observing and controlling quantum phenomena on a nanometric scale. We introduce the 2D materials class, such as hBN and TMDs, and their relevance as single photon emitters, quantum sensors, and optoelectronic and photonic devices. We discuss the mechanisms behind the generation of radiative defects and the properties of twisted-heterostructures and spin-orbit coupling, emphasizing the potential for operation at room temperature. Lastly, we underscore these systems’ educational and interdisciplinary impact, enabling accessible experimental approaches for higher education and science outreach. 2D materials bring together theory, technique, and accessibility, becoming allies in forming professionals who are prepared to promote the concepts of quantum physics in a clear and inclusive manner.
