Making progress: this latest achievement in entanglement could lead to better quantum computers. (Courtesy: iStock/Devrimb) A protocol for entangling microwave and optical photons has been demonstrated by researchers in Austria. This has the potential to help to overcome one of the central issues in the formation of a quantum internet by allowing microwave frequency circuits

Glaciers accumulate significant amounts of fallout radionuclides from nuclear accidents and weapons testing – sometimes in the highest radioactive concentrations ever found outside of nuclear exclusion zones and test sites. Michael Allen digs into the depths of this unexpected issue and the associated risks as glaciers melt Think of glaciers and images of vast, pristine
