"coherent control ultrabright single spin hexagonal boron nitride room temperature... nitrogen-vacancy diamond center... negatively charged boron vacancy... ultrabright single-spin color centers 85% probability, which is enhanced 21X... photon emissivity 25 MHz... captured its Rabi oscillation signal and conducted Hahn echo experiments. It was the first time that a single-spin color center in hBN was manipulated at room temperature, representing a new stage in the application of quantum information"
