In an exciting development that could revolutionize several industries, researchers at the University of Calgary have made a groundbreaking discovery regarding the use of diamonds in quantum technology. This revelation may transform our understanding of materials science, particularly in how diamonds can be employed in data centers and laser manufacturing.
An age-old adage about diamonds might have become outdated by 2026, as today, diamonds are proving to be invaluable resources for quantum scientists. This shift in perception stems from a remarkable research paper published in December 2025 by the Quantum Nanophotonics Lab at the University of Calgary, which explored the fundamental characteristics of diamonds and their application in the field of quantum nanophotonics. Simply put, quantum nanophotonics deals with the tiny structures that influence the way light behaves at a quantum level.
The research team was able to demonstrate a phenomenon known as second-harmonic generation, which involves converting one color of light into another by altering the frequency and wavelength of a light wave when interacting with diamonds. Traditionally, it was thought that the symmetrical crystalline structure of diamonds prevented such optical transformations from occurring.
Dr. Paul Barclay, a professor in the Department of Physics and Astronomy and head of the Quantum Nanophotonics Lab, expressed the significance of this discovery. "Not only are we challenging conventional wisdom by observing these effects, but we’ve also found a way to control the extent to which we are defying those conventions," he explained in an interview with BetaKit.
Diamonds have not been recognized in the past as suitable candidates for these kinds of effects due to inherent limitations tied to their crystal structure. However, this research team cleverly utilized minute defects within the diamond’s crystal lattice to bypass these restrictions, opening the door to innovative applications within quantum nanophotonics.
Sigurd Flågan, a postdoctoral researcher in the lab who spearheaded the experimental work leading up to this finding, noted the exceptional durability of diamonds when handling high-powered lasers. "Diamonds can endure substantial amounts of laser energy without sustaining damage," he stated. As a result of this discovery, he added, it is now feasible to create optical switches, lasers, or modulators that can manage significantly higher power levels than what is currently possible.
Practical implications of this research could lead to advancements in various areas, including enhanced capabilities in data centers, high-powered laser manufacturing, and refined optical processing techniques.
While the lab’s findings were published just last month, Flågan shared that the research journey has spanned several years, beginning with initial observations made three years ago. "The experiments conducted at the end of 2023 extended into 2024. Yet, it wasn't until early 2025 that we fully understood the model behind what we observed," he revealed.
This research initiative is supported in part by YEGAF, a nonprofit organization focused on highlighting business stories in Alberta, which reflects the growing interest in technological advancements in the region.
