Use of AI: Placebo effect increases risk-taking

Human augmentation technologies refer to technological aids that enhance human abilities. They include things like exoskeletons, but also augmented reality headsets. A study at the Chair of Human-Centered Ubiquitous Media at LMU has now shown that users have high expectations of the effects of these technologies. As soon as they believe that AI is enhancing their cognitive abilities, they increase their risk-taking. And they do this independently of whether the AI is actually assisting them. “The hype around AI applications affects the expectations of users. This can lead to riskier behavior,” says Steeven Villa, doctoral researcher ...

Boost for the quantum internet

Quantum networks connect quantum processors or quantum sensors with each other. This allows tap-proof communication and high-performance distributed sensor networks. Between network nodes, quantum information is exchanged by photons that travel through optical waveguides. Over long distances, however, the likelihood of photons being lost increases dramatically. As quantum information cannot simply be copied and amplified, 25 years ago Hans Briegel, Wolfgang Dür, Ignacio Cirac and Peter Zoller, then all at the University of Innsbruck, provided the blueprints for a quantum repeater. These feature light-matter entanglement sources and memories ...
