New nanohole-based microscopy monitors electrochemical reactions millisecond by millisecond

Many technological applications, such as sensors and batteries, greatly rely on electrochemical reactions. Improving these technologies depends on understanding how electrochemical reactions work. However, most current methods cannot look at electrochemical reactions in detail.

Scientists at Utrecht University have now developed a new method that overcomes this limitation. This provides a powerful new way to study and improve electrochemical processes. The study is published in PNAS.

Hydrogen production by water electrolysis is one example where electrochemical reactions at electrodes matter for sustainable technology. But the decisive steps happen within just a few nanometers of the electrode surface, which is too small for most conventional methods to resolve.

Optical switch protocol verifies entangled quantum states in real time without destroying them

The fragility and laws of quantum physics generally make the characterization of quantum systems time‑consuming. Furthermore, when a quantum system is measured, it is destroyed in the process. A breakthrough by researchers at the University of Vienna demonstrates a novel method for quantum state certification that efficiently verifies entangled quantum states in real time without destroying all available states—a decisive step forward in the development of robust quantum computers and quantum networks.

The work was carried out in Philip Walther’s laboratories at the Faculty of Physics and the Vienna Center for Quantum Science and Technology (VCQ) and published in the journal Science Advances.

Entangled quantum states are the fundamental building blocks of many new quantum technologies, from ultra‑secure communication to powerful quantum computing. However, before these delicate states can be used, they must be rigorously verified to ensure their quality and integrity.
