Using one of the world’s most advanced spectroscopy systems, researchers have developed a framework to guide studies in next-generation quantum information technologies.
For the first time, scientists in the Femtosecond Spectroscopy Unit at the Okinawa Institute of Science and Technology (OIST) have directly tracked how dark excitons evolve in atomically thin materials. This achievement paves the way for advances in both classical and quantum information technologies. The study was published in Nature Communications.
Professor Keshav Dani, who leads the unit, emphasized the importance of the work: “Dark excitons have great potential as information carriers, because they are inherently less likely to interact with light, and hence less prone to degradation of their quantum properties. However, this invisibility also makes them very challenging to study and manipulate. Building on a previous breakthrough at OIST in 2020, we have opened a route to the creation, observation, and manipulation of dark excitons.”
