CVD diamond-based quantum information storage equipment and preparation method thereof

The invention relates to the technical field of quantum computing, and further discloses CVD diamond-based quantum information storage equipment. The CVD diamond-based quantum information storage equipment comprises an outer shell, an inner shell, a main board, a CVD diamond wafer, a monochromatic laser and a microwave coil, the bottom of the inner shell is fixedly arranged at the bottom of the outer shell; the main board is horizontally positioned in the inner shell; insertion holes are formed in four corners of the surface of the main board; a screw rod is movably sleeved with each of the plurality of inserting holes; the lower ends of the plurality of screw rods are fixedly connected with the bottom of the inner shell; springs are movably connected to the rod walls of the multiple screws and located below the main plate in a sleeving mode. The lower ends of the springs are fixedly connected with the bottom of the inner shell, the upper ends of the springs are fixedly connected withthe lower surface of the
