Optical fibers are the backbone of our modern information networks. From long-range communication over the internet to high-speed information transfer within data centers and stock exchanges, optical fiber remains critical in our globalized world. Click […]
An international team of scientists collaborating within the Würzburg-Dresden Cluster of Excellence ct.qmat has achieved a breakthrough in quantum research—the first detection of excitons (electrically neutral quasiparticles) in a topological insulator. Click to rate this […]
Heat and computers do not mix well. If computers overheat, they do not work well or may even crash. But what about the quantum computers of the future? These high-performance devices are even more sensitive […]
Approximately two decades ago, it was shown theoretically that quantum computers could easily solve certain computationally demanding problems like factoring large numbers into prime numbers or searching efficiently in databases. These possibilities have triggered intense […]
Controlling the internal states of quantum systems is one of the biggest challenges in quantum materials. At the deepest level, single molecules can display different quantum states, even while possessing the same number of electrons. […]
Weyl semimetals are topological materials whose low-energy excitations obey the Weyl equation. In a Weyl semimetal, the conduction and valence bands touch at discrete points in momentum space called Weyl nodes. Weyl nodes are monopoles […]
Topology refers to the overall property that remains unchanged despite continuous local modifications. A coffee cup and a donut are no different to mathematicians because they have the same topological charge. Materials with various topological […]
Quantum computers hold the promise of performing certain tasks that are intractable even on the world’s most powerful supercomputers. In the future, scientists anticipate using quantum computing to emulate materials systems, simulate quantum chemistry, and […]
Neutrinos mind their own business. Each second, billions of these fundamental particles will pass through stars, planets, buildings, and human bodies and will rarely ever be stopped by them, like a subatomic subway crowd. It’s […]
Nuclear physicists have found a new way to use the Relativistic Heavy Ion Collider (RHIC)—a particle collider at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory—to see the shape and details inside atomic nuclei. […]
