On April 25th, according to media reports, Japan’s Adamant Namiki Precision Jewelry Society and Shiga University jointly announced that they have successfully achieved mass production of diamond wafers on April 19th, which will be dedicated to the storage medium of quantum computers in the future.
The single 55mm wafer can store the equivalent of 1 billion Blu-ray discs, or 25 exabytes, and is scheduled to be put into production in 2023.
The material of this diamond wafer is ultra-high-purity diamond with nitrogen concentration controlled below 3ppb (3 parts per billion), so as to ensure that there will not be too many voids generated by nitrogen inside the wafer, so as to achieve this Amazing storage density.
Encyclopedia data shows that exabytes, the unit of computer storage capacity, is also commonly expressed in EB. In conversion, 1EB=1024PB, 1PB=1024TB, 1TB=1024GB.
PS: Wafer refers to the silicon wafer used to make silicon semiconductor circuits, and its original material is silicon. High-purity polysilicon is dissolved and mixed with silicon crystal seeds, which are then slowly pulled out to form cylindrical monocrystalline silicon. The silicon ingot is ground, polished and sliced to form a silicon wafer, that is, a wafer.
