Erbium-implanted silicon is promising for both photonic and quantum-technology platforms, since it possesses both telecommunications and integrated-circuit processing compatibility. However, several differentcenters are generated during the implantation and annealing process, the presence of which could hinder the development of these applications. Whenis coimplanted withandions, and the appropriate annealing process is used, one of these centers, which is present at higherconcentrations, can be eliminated. Characterization of samples withconcentrations of <is limited by the sensitivity of standard electron paramagnetic resonance (EPR) instruments. The collective coupling strength between a superconducting (SC)lumped-element resonator and a-implantedsample at 20 mK is measured to be about 1 MHz, which provides a basis for the characterization of low-concentration-implantedand for future networks of hybrid quantum systems that exchange quantum information over the telecommunication network. Of six known-related EPR centers, only one trigonal center couples to the SC resonator.
