Rydberg atoms and molecules are characterized by having one or more electrons in highly excited bound states. Such atoms and molecules are said to be in “Rydberg states” and are also called “hollow” atoms and […]

After several years of operation, the STEREO collaboration published the final results of their antineutrino studies. With their data, the researchers excluded hints for the existence of sterile neutrinos, an additional neutrino state expected in […]
“Suppose you knew everything there was to know about a water molecule—the chemical formula, the bond angle, etc.,” says Joseph Thywissen, a professor in the Department of Physics and a member of the Centre for […]
The early 20th century saw the advent of quantum mechanics to describe the properties of small particles, such as electrons or atoms. Schrödinger’s equation in quantum mechanics can successfully predict the electronic structure of atoms […]
One of the biggest achievements of quantum physics was recasting our vision of the atom. Out was the early 1900s model of a solar system in miniature, in which electrons looped around a solid nucleus. […]
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. […]
