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 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.
However, truly scalable systems require integration of all passive and active photonic devices on the same chip, including sources. Following the same advances in design, fabrication, and heterogenous integration, even Titanium:sapphire laser, the workhorse of optics laboratories, can be miniaturized into sub-cubic centimeter volume together with its pump. We demonstrate such a laser, and show how it can replace commercial tabletop Ti:sapphire lasers in our quantum optics experiments without any loss in performance.
