The quantum computers that will equip our offices in the coming years will be able to store a huge amount of data, with the help of the original hosting system: diamonds!
For several years, researchers around the world have been very interested in the properties of diamonds for storing data in quantum computers. Japanese company Namiki Precision Jewel developed with the help of Saga University, Diamond 5.5 cm Capable of hosting the equivalent of 1 billion Blu-ray discs, which is equivalent to 25 exabytes or 25 billion gigabytes!
Diamond as a hard disk
According to Namiki, this is the equivalent of all mobile data distributed across the world in one day. Something that makes you feel comfortable on a daily basis… Using diamonds to store data is the preferred method in quantum computers. Its structure already contains a defect, the nitrogen vacancy center (or “NV”), where the data can be accommodated.
This data is not classic 0 or 1 bit, quantum computing is organized around qubits which can be 0 and 1. It is up to the computer to organize them according to its needs. Their storage is made possible by magnetic traps that absorb positive ions.
The researchers explain that The NV center consists of a nitrogen atom and a corresponding vacancy in the diamond lattice “The NV center will form a small magnetic force and.” It acts as a quantum memory at the atomic level However, things are not that easy (it really isn’t when we talk about quantum…): too much nitrogen can degrade diamond’s storage properties.
So a diamond must be large enough and very pure to do its job of storing quantum bits. The one who made it Namiki (called Kenzan DiamondIt offers these features: With a height of 5.5 cm, it is a “slice” of diamond that could be marketed next year. The researchers are already working on a model twice as large.
