  Solid-state color centers with manipulatable spin qubits and telecom-ranged
fluorescence are ideal platforms for quantum communications and distributed
quantum computations. In this work, we coherently control the nitrogen-vacancy
(NV) center spins in silicon carbide at room temperature, in which
telecom-wavelength emission is detected. We increase the NV concentration
six-fold through optimization of implantation conditions. Hence, coherent
control of NV center spins is achieved at room temperature and the coherence
time T2 can be reached to around 17.1 {\mu}s. Furthermore, investigation of
fluorescence properties of single NV centers shows that they are room
temperature photostable single photon sources at telecom range. Taking
advantages of technologically mature materials, the experiment demonstrates
that the NV centers in silicon carbide are promising platforms for large-scale
integrated quantum photonics and long-distance quantum networks.
