Quantum computers become ever more powerful, but how can we be sure that the answers they return are accurate? A team of physicists from Vienna, Innsbruck, Oxford, and Singapore solves this problem by letting quantum computers check each other. Quantum computers are advancing at a rapid pace and ...
Researchers at the University of Vienna’s Faculty of Physics in collaboration with colleagues from the Oak Ridge National Laboratory in the USA have uncovered a non-destructive mechanism to manipulate donor impurities within silicon using focused electron irradiation. In this novel indirect ...
"We are excited of the prospect of creating new materials that are designed starting at the atomic level, based on this method"
Properties of materials are often defined by imperfections in their atomic structure, especially when the material itself is just one atom thick, such as graphene. Researchers at the University of Vienna have now developed a method for controlled creation of such imperfections into graphene at ...
Analysis of particularly complex gas mixtures with unprecedented accuracy
In an international cooperation with partners from industry and research, physicists from the University of Vienna, together with Thorlabs, the National Institute of Standards and Technology (NIST), and the University of Kansas, have now succeeded for the first time in demonstrating ...
Structures built around a single layer of graphene allow for strong optical nonlinearities
A wide array of technologies, ranging from lasers and optical telecommunication to quantum computing rely on nonlinear optical interaction. Typically, these nonlinear interactions, which allow a beam of light, for example, to change its frequency, are implemented by bulk materials. In a new study ...
Helium ions create and heal radiation damage
Several minerals suffer radioactive self-irradiation and hence experience long-term changes of their properties. The mineral monazite virtually behaves "just alike Camembert cheese in which holes are drilled": Existing radiation damage heals itself. An international research team led by Lutz ...
Cutting-edge technology allows for real-time monitoring of biomineralisation
21st century societal challenges such as demographic developments and an ageing population demand for new functional materials, such as for bone prostheses. Nature often serves as inspiration when designing these materials. In a recent study published in Analytical Chemistry, a team led by ERC ...
International research project observes ultrafast particle growth through ammonia and nitric acid
When winter smog takes over Asian mega-cities, more particulate matter is measured in the streets than expected. An international team, including researchers from Goethe University Frankfurt, as well as the universities in Vienna and Innsbruck, has now discovered that nitric acid and ammonia in ...
Researchers from Graz University of Technology and the University of Vienna are demonstrating for the first time how the energy flow between strongly interacting molecular states can be better described. Since the 1990s, femtochemistry has been researching ultrafast processes at the molecular ...
Physicists at the University of Vienna in collaboration with the Max Planck Institute for Polymer Research have discovered a new type of glass formed by long, cyclic molecules. The scientists successfully demonstrated that by making parts of the rings more mobile, the rings become more strongly ...
