A challenge in building scalable quantum networks is connecting different quantum systems that operate using photons at different frequencies. A study published in Advanced Photonics Nexus investigates four-wave mixing in gas-filled hollow-core fibers as a method for converting photons between frequency bands while preserving the quantum information they carry. The study demonstrates that this approach preserves the properties of light needed for quantum information transfer, providing a potential pathway toward large-scale quantum networks.

New research from the University of Colorado Boulder could lead to big advances in passenger jet aerodynamic performance and fuel economy

A major two-year trial by RMIT University, Westernport Water and Australia’s national science agency CSIRO measured the impact of floating platforms of native plants on greenhouse gas emissions from a wastewater lagoon in Phillip Island, southeast Australia.  

The results published in the Journal of Environmental Management reveal dramatic results, with CO₂ emissions dropping by up to 36%, methane by up to 66% and nitrogen by 18% in the lagoon with a floating wetland installed, compared to the control lagoon with no wetland platform. 

A simple ball-milling process dramatically enhanced the antiviral activity of manganese-based oxides, as reported by researchers from Science Tokyo. The team treated four manganese-containing materials with ball milling in ethanol, which altered their surface chemistry and greatly improved their ability to inactivate an enveloped virus similar to SARS-CoV-2. The findings reveal a promising strategy for designing low-cost, high-performance antiviral materials for coatings and other self-disinfecting surfaces.
