  • Spin systems in solid state materials are promising qubit candidates for quantum information or quantum sensing. A major prerequisite here is the spin coherence time. In this work, we show a spin control sequence which, by applying RF pulses of variable detuning, allows the inhomogeneous $T_2^*$ time to be increased while retaining the spin phase oscillations as a primary figure of merit for coherence. We experimentally demonstrate the scheme on single NV centers in diamond and analytically… CONTINUE READING
