A central challenge for scalable quantum computing, sensing, and networking is the creation and distribution of entanglement among multiple individually-addressable qubits. Color centers in silicon emitting at telecommunications wavelengths have emerged as a promising candidate for optically-addressable qubits that are compatible with existing mature semiconductor and telecommunication industry platforms. We demonstrate silicon color centers coupled to foundry-compatible silicon waveguides. We produced G-centers via carbon implantation in commercial silicon-on-insulator waveguides and measure through-waveguide single-photon emission in the telecommunications O-band.
