摘要
Megabar pressures are of crucial importance for cutting-edge studies of condensed matter physics and geophysics.With the development of diamond anvil cell(DAC),laboratory studies of high pressure have entered the megabar era for decades.However,it is still challenging to implement in situ magnetic sensing under ultrahigh pressures.In this work,we demonstrate optically detected magnetic resonance and coherent quantum control of diamond nitrogen-vacancy(NV)center,a promising quantum sensor inside the DAC,up to 1.4 Mbar.The pressure dependence of optical and spin properties of NV centers in diamond are quantified,and the evolution of an external magnetic field has been successfully tracked at about 80 GPa.These results shed new light on our understanding of diamond NV centers and pave the way for quantum sensing under extreme conditions.
