Hidden side channels of quantum sources can impair secure communication
Amita Gnanapandithan, a PhD student at the University of Toronto Engineering, demonstrated the existence of a “hidden” side channel in devices that generate photons used in quantum communications using both practical experiments and computer modeling. Credit: University of Toronto Engineering/Tyler Irving A team of researchers at the University of Toronto Engineering discovered a multidimensional side channel hidden in existing quantum…

The world’s first quantum microsatellites demonstrate secure communication with multiple ground stations
Schematic diagram of quantum key distribution experiments between quantum microsatellite zinan-1 and ground stations. Credit: Nature (2025). doi:10.1038/s41586-025-08739-z The research team developed the world’s first quantum microsatellite, demonstrating real-time quantum key distribution (QKD) between satellites and multiple compact mobile ground stations. The research led by USTC’s Pan Jianwei, Peng Chengzhi and Liao Shengkai has been published in collaboration with the…

Thousands of small, time sensors that secure time can collectively map chemical concentration in a narrow tube.
The human intestinal system (A) can be represented as a series of plugflow reaction devices (B), a model that describes a chemical reaction in the flowing cylindrical system. Time recognition particles (C) pass through the plugflow system and detect interest chemicals known as analysis. Credit: Manion et al. , 2025. A diagram made partially in a violence. When synthesizing chemicals,…
