Adding bridges to stabilize quantum networks

Thu, 01/23/2025 - 4:31pm
While entangled photons hold incredible promise for quantum computing and communications, they have a major inherent disadvantage. After one use, they simply disappear. In a new study physicists propose a new strategy to maintain communications in a constantly changing, unpredictable quantum network. By rebuilding these disappearing connections, the researchers found the network eventually settles into a stable -- albeit different -- state.

Artificial intelligence in biomedicine: A key to analyzing millions of individual cells

Thu, 01/23/2025 - 10:18am
Our bodies are made up of around 75 billion cells. But what function does each individual cell perform and how greatly do a healthy person's cells differ from those of someone with a disease? To draw conclusions, enormous quantities of data must be analyzed and interpreted. For this purpose, machine learning methods are applied. Researchers have now tested self-supervised learning as a promising approach for testing 20 million cells or more.

Scientists harness the power of 'layered' crystals for energy innovation

Tue, 01/21/2025 - 1:23pm
Scientists are unlocking the secrets of halide perovskites -- a material that's poised to reshape our future by bringing us closer to a new age of energy-efficient optoelectronics. Two physics professors are studying the material at the nanoscale: a place where objects are invisible to the naked eye. At this level, the extraordinary properties of halide perovskites come to life, thanks to the material's unique structure of ultra-thin crystals -- making it astonishingly efficient at converting sunlight into energy. Think solar panels that are not only more affordable but also far more effective at powering homes. Or LED lights that burn brighter and last longer while consuming less energy.
