A team of Louisiana researchers, including a group from the Tulane University School of Science and Engineering, has developed a smart quantum technology that could have real-world applications to quantum networks and future quantum communications systems used in the military. Ryan Glasser, an associate professor of physics at Tulane, and his team in the Department of Physics, collaborated on the study with researchers from Louisiana State University. The study was featured on the cover of the March 2021 issue of “Recent developments in optical technologies have resulted in extremely high information transfer rates using the spatial properties of light i.e. images (and more complex structured beams),” Glasser said. “However, a difficulty in such communications using light through free-space is that turbulence can severely distort the beams, resulting in errors in the communication.” ....
E-Mail Researchers from Louisiana State University have introduced a smart quantum technology for the spatial mode correction of single photons. In a paper featured on the cover of the March 2021 issue of Advanced Quantum Technologies, the authors exploit the self-learning and self-evolving features of artificial neural networks to correct the distorted spatial profile of single photons. The authors, PhD candidate Narayan Bhusal, postdoctoral researcher Chenglong You, graduate student Mingyuan Hong, undergraduate student Joshua Fabre, and Assistant Professor Omar S. Magaña?Loaiza of LSU together with collaborators Sanjaya Lohani, Erin M. Knutson, and Ryan T. Glasser of Tulane University and Pengcheng Zhao of Qingdao University of Science and Technology report on the potential of artificial intelligence to correct spatial modes at the single-photon level. ....
LSU researchers are building a quantum simulator to study how light interacts with different materials in solar cells to increase their efficiency. LSU Physics professor Omar Magana-Loaiza and postdoctoral researcher Chenglong You received a grant from the U.S. Department of Energy to build a one-of-a-kind quantum device. Their research could help scientists find better materials to build solar cells and make them more efficient. The sun emits light made up of speeding photons that travel to the Earth, and solar cells convert the energy of those photons into electrical energy. Most solar cells are made from crystalline silicon, a semiconductor material that helps transport photons in the conversion of light energy to electrical energy. ....
