(color online) The schematic of the experimental setup. A 532-nm laser was used for the initialization and readout of the NV electron spin. Control of the spin was realized through the resonant microwave pulse radiated from a copper wire mounted on the diamond. A static vector magnetic field is applied. NV frame of reference is defined by x, y, and z axes, where ϕ and θ represent the azimuth and polar angles with respect to the x and z axes respectively.
