Diamond Magnetometer and Precision Metrology

Principal Investigator Paola Cappellaro


In recent years metrology and quantum information science have emerged as complementary areas of research. We aim at applying the principles of quantum information science to the development of nano-scale magnetic field sensors based on single spin qubits in diamond. We focus on improving the diamond magnetometer readout, enhancing its coherence, improving its spatial resolution and devising strategies to achieve sensitivity beyond the Heisenberg limit. Ideas and techniques from quantum information science are critical in achieving these goals, from quantum non-demolition measurement, to dynamical decoupling and spin squeezing.
