Description
Quantum metrology based on solid-state color centers has advanced significantly through the development of robust sensing protocols, including Ramsey interferometry, Hahn echo, and dynamical decoupling sequences. Color center qubits are particularly promising platforms for quantum sensing due to their ability to operate under a wide range of conditions, from vacuum to ambient environments and from cryogenic to room temperatures, depending on the application. In this talk, I will introduce the fundamental principles of quantum metrology using solid-state color centers, with a particular focus on defect qubits in diamond. I will then discuss recent efforts to achieve quantum-enhanced sensing by exploiting quantum correlations among defect qubits. Finally, I will highlight emerging applications of color center qubits in particle physics, including the search for axion dark matter, and present ongoing experimental efforts in this direction.
