The lower Er concentration samples of 1016 cm-3 showed inhomogeneous broadening of less than 100 MHz. Using bichromatic excitation, we were able to polarize the spin states and extract a site that is present in the high and low oxygen concentration samples. The measured lifetime of the electron spin in the optical ground state was as long as 30 seconds at a magnetic field of 60 mT and a temperature of 20 mK. By introducing a wire antenna, we observed Rabi oscillations of over 1 MHz. These narrow optical linewidths and long spin lifetimes show that Er in Si is a promising candidate for future quantum information processing applications.
