The sensible blue of the Hope Diamond is brought on by small impurities in its crystal construction. Comparable diamond impurities are additionally giving hope to scientists trying to create supplies that can be utilized for quantum computing and quantum sensing.

In new analysis from the U.S. Division of Vitality’s (DOE) Argonne Nationwide Laboratory, researchers have created extraordinarily skinny membranes of pure diamond. In a number of areas within the of the membrane, nonetheless, the staff substituted with different atoms, notably nitrogen. These defects hook up with neighboring atomic vacancies—areas the place an atom is lacking—creating uncommon quantum methods generally known as “coloration facilities.” Such coloration facilities are websites for storing and processing quantum data.

Geared up with a solution to cheaply and simply create diamond membranes which have strong coloration facilities, scientists at Argonne hope to construct a form of meeting line for producing massive numbers of those membranes for quantum experiments all over the world.

The flexibility to develop the membranes could possibly be the ticket to enhancing collaboration between completely different laboratories dedicated to quantum data science, stated College of Chicago graduate scholar Xinghan Guo, lead creator of the examine.

“Primarily, we hope this can finally give us the power to turn into a one-stop store for quantum sensing supplies,” Guo stated.

“The defects within the diamond are fascinating to us as a result of they are often exploited for quantum utility,” stated Nazar Delegan, scientist in Argonne’s Supplies Science division and the Pritzker College of Molecular Engineering on the College of Chicago and a collaborator with Q-NEXT. “Making these membranes permits us to combine these defects with different methods and allows new experimental configurations.”

Diamond is mechanically arduous, chemically secure and usually costly—in different phrases, it’s form of a scientific nightmare, notoriously troublesome to manufacture and combine. On the similar time, diamond’s explicit construction makes it a terrific host for coloration facilities that may retailer quantum data for a very long time, Guo stated.

“Typical diamond as a substrate is tremendous arduous to work with,” he stated. “Our membranes are thinner and extra accessible for a variety of experiments.”

The brand new diamond materials common by the researchers provides larger crystal and floor high quality, enabling larger management over the coherence of the colour facilities.

“You possibly can peel the off and put it on a variety of substrates, even put it on a silicon wafer. It is an affordable, versatile and simple approach of working with with out having to work instantly with typical diamond,” Guo stated.

“As a result of we’re capable of management and preserve the quantum properties in particular person defects inside these very skinny supplies, it makes this platform promising as foundation for a quantum applied sciences,” Delegan stated.

A paper based mostly on the examine appeared within the December 13, 2021, on-line version of Nano Letters.
