Title:  Quantum technologies with semiconductor color centers in integrated photonics Abstract: Optically interfaced spin qubits based on diamond and silicon carbide color centers are considered promising candidates for scalable quantum networks and sensors. However, they can also be used to build chip-scale quantum many body systems with tunable all to all interactions between qubits enabled by photonics - useful for quantum simulation and possibly computing. Our recent efforts have focused on tin-vacancy (SnV-) color center in diamond where we have shown high fidelity microwave control of an electron-spin at 1.7K temperature, high fidelity single shot (optical) readout of an electron spin, high quality quantum photonic interface, and even heterogeneous integration with lithium niobate for frequency conversion, making this color center very interesting candidate for implementation of quantum networks. Moreover, our recent demonstration of coherent and controlled interactions of multiple qubits (silicon vacancy - VSi color centers) inside a single silicon carbide resonator has established these systems as promising candidates  for  other quantum technologies, including quantum simulation and possibly even quantum computing. We also show how chip-scale Ti:sapphire laser can replace commercial tabletop lasers in our quantum optics experiments without any loss in performance, leading to truly scalable quantum systems on chip.
