An international research team has demonstrated that the intrinsic disorder of the compound semiconductor CuInSnS₄ can be exploited to influence its optical properties. While the atomic vibrations also sense the local disorder, their response is averaged over many different local environments and therefore appears isotropic, as expected for a cubic crystal.
The Korea Research Institute of Standards and Science (KRISS) has developed a room-temperature single-photon source built into a compact 19-inch rack-mounted device that operates without cryogenic cooling. Designed as a plug-and-play system that works as soon as it is powered on, the device moves quantum light source technology beyond the laboratory and closer to practical, onsite use.

Researchers at ETH Zurich have developed a method that uses a single ion to detect electromagnetic fields above a surface and to create a three-dimensional map of them. In the future, this approach can be used to improve chips for quantum computers and quantum sensors.

Researchers from the Molecular Physics and Physical Chemistry departments of the Fritz Haber Institute have shown how two highly synchronized infrared (IR) laser beams can control molecules as they switch between different structural conformations. Their study provides a new window into how molecules rearrange themselves during chemical reactions, offering fundamental insights into the microscopic
