TL;DR: A workforce from Japan has created the biggest diamond storage machine ever, capable of maintain as much as 25 exabytes. Though supposed to be used as quantum reminiscence, the 2-inch diamond wafer is notable for being usable even at room temperature. The corporate manufacturing it plans to commercialize it subsequent 12 months.
Japanese researchers, alongside an organization specializing in industrial jewel parts, have developed a brand new methodology of mass-producing 2-inch diamond wafers. Dubbed Kenzan Diamonds, these could possibly be used to retailer as much as 25 exabytes of knowledge, which is 25 million terabytes or the equal of 1 billion Blu-Ray discs.
Sadly, these diamond wafers will not be changing the SSDs in our PCs anytime quickly as they act as quantum reminiscence. It makes use of a defect in diamond, referred to as the nitrogen-vacancy middle, to retailer a quantum bit.
This defect permits researchers to learn out the particular spin of an electron. It is notable as a result of these diamond qubits can be utilized even at room temperature, not slightly below the cryogenic circumstances that quantum computer systems normally require.
Beforehand, a diamond wafer with the mandatory purity for quantum computing functions was restricted to only a 4mm sq.. Trying to fabricate larger wafers would introduce larger ranges of nitrogen impurities, rendering them ineffective.
Researchers from Saga College teamed up with Adamant Namiki Precision Jewel Co. to resolve this drawback. Utilizing a course of referred to as step move development, they develop the diamonds on a sapphire substrate coated with an iridium movie. They declare this new methodology makes it cheaper to supply the diamonds whereas minimizing nitrogen absorption, conserving it under three elements per billion.
The corporate plans to introduce Kenzan Diamond wafers commercially subsequent 12 months, and it’s already engaged on growing 4-inch wafers.
