This pocket-sized diamond wafer may retailer as much as 25 exabytes

TL;DR: A workforce from Japan has created the most important diamond garage tool ever, in a position to carry as much as 25 exabytes. Even though meant to be used as quantum reminiscence, the 2-inch diamond wafer is notable for being usable even at room temperature. The corporate production it plans to commercialize it subsequent yr.

Jap researchers, along an organization that specialize in commercial jewel parts, have evolved a brand new manner of mass-producing 2-inch diamond wafers. Dubbed Kenzan Diamonds, those might be used to retailer as much as 25 exabytes of knowledge, which is 25 million terabytes or the similar of one billion Blu-Ray discs.

Sadly, those diamond wafers may not be changing the SSDs in our PCs anytime quickly as they act as quantum reminiscence. It makes use of a defect in diamond, known as the nitrogen-vacancy middle, to retailer a quantum bit.

This defect lets in researchers to learn out the precise spin of an electron. It is notable as a result of those diamond qubits can be utilized even at room temperature, now not slightly below the cryogenic stipulations that quantum computer systems typically require.

Up to now, a diamond wafer with the vital purity for quantum computing packages used to be restricted to only a 4mm sq.. Making an attempt to fabricate larger wafers would introduce upper ranges of nitrogen impurities, rendering them unnecessary.

Researchers from Saga College teamed up with Adamant Namiki Precision Jewel Co. to unravel this drawback. The use of a procedure known as step float enlargement, they develop the diamonds on a sapphire substrate lined with an iridium movie. They declare this new manner makes it inexpensive to supply the diamonds whilst minimizing nitrogen absorption, protecting it under 3 portions in keeping with billion.

The corporate plans to introduce Kenzan Diamond wafers commercially subsequent yr, and it’s already operating on growing 4-inch wafers.
