Color centers in silicon are leading qubits for scalable quantum information processing. We will discuss recent developments towards a technological platform including the formation of waveguide-integrated color centers, their spectral control, and on-chip single-photon detection.

We demonstrate controllable and reversible spectral tuning of a single quantum emitter in a silicon photonic integrated circuit, achieving up to 400 pm shift at telecom wavelength, paving the way for monolithically integrated quantum technologies.
