Freeze-frame: U of A researchers develop microscope that can see electrons in motion
Posted by Omuterema Akhahenda in categories: bioengineering, chemistry, quantum physics
Imagine owning a camera so powerful it can take freeze-frame photographs of a moving electron – an object traveling so fast it could circle the Earth many times in a second. Researchers at the University of Arizona have developed the world’s fastest electron microscope that can do just that.
They believe their work will lead to groundbreaking advancements in physics, chemistry, bioengineering, materials sciences and more.
“When you get the latest version of a smartphone, it comes with a better camera,” said Mohammed Hassan, associate professor of physics and optical sciences. “This transmission electron microscope is like a very powerful camera in the latest version of smartphones; it allows us to take pictures of things we were not able to see before – like electrons. With this microscope, we hope the scientific community can understand the quantum physics behind how an electron behaves and how an electron moves.”

Researchers use high-performance computing to analyze a quantum photonics experiment
Posted by Saúl Morales Rodriguéz in categories: computing, quantum physics
For the first time ever, scientists at Paderborn University have used high-performance computing (HPC) at large scales to analyze a quantum photonics experiment. In specific terms, this involved the tomographic reconstruction of experimental data from a quantum detector. This is a device that measures individual photons.

Zero Resistance Breakthrough: Meet the Quantum Sandwich Powering the Future
Posted by Saúl Morales Rodriguéz in categories: computing, quantum physics
Researchers have developed a new “sandwich” structure material that exhibits the quantum anomalous Hall effect, enabling electrons to travel with almost no resistance at higher temperatures.
This breakthrough could significantly enhance computing power while dramatically reducing energy consumption. The structure is based on a layered approach with bismuth telluride and manganese bismuth telluride, promising faster and more efficient future electronic devices.
