Semiconductor platforms based on color centers are suitable for implementing scalable quantum systems, based on excellent spin quantum memories with direct photonic interfaces, the possibility to perform high speed and high fidelity quantum gates, combined with expertise in scaling semiconductor circuits. However, there are many remaining challenges to address, including color centers integration into optical structures, as well as the inhomogeneity and imperfections of the qubits resulting from the nonuniform solid state environment. We show how a combination of new computational techniques, nanofabrication approaches, and fast optical and electrical control offers a unique way to address these challenges and to implement scalable quantum systems in diamond and silicon carbide.
