Quantum computing is still in its infancy. But it has an incredible potential to solve problems that are beyond the reach and speed of conventional high-performance computers.

A Japanese company Adamant Namiki Precision Jewelry Company, working with researchers from Saga University in Kyushu, Japan has developed a new method to produce diamond wafers that could soon be used in quantum computers. This technology could lead to the realization of quantum computers in the future.

Diamonds are one of the most promising materials for quantum computing systems. But too much nitrogen in a diamond disrupts its quantum storage capabilities.

The diamond wafers measuring two inches developed by Japanese researchers have a nitrogen purity that’s less than three PPB.  Until now, the available diamond wafers with the required purity were too small (up to 4mm square) to be used in quantum computing applications.

Kenzan Diamonds” are pure enough to be used in quantum computing

Called Kenzan Diamond, these diamond wafers have such immense data density that they can store the data equivalent of a billion Blu-Ray discs.

While one Blu-Ray can store up to 25 GB, this diamond wafer could store a whopping 25 exabytes (EB) equivalent to one billion Blu-Ray discs of data due to the ultra-high purity of the diamond.

Adamant Namiki is working on doubling the size of the wafers and plans to commercialize Kenzen Diamonds next year.
