In a breakthrough study, scientists have demonstrated nonlocal effects in biexciton emission. Biexcitons are two-electron complexes created by the recombination of two excited electrons in a semiconductor material. They are of great interest to researchers due to their potential applications in quantum information processing and optoelectronics.

Using a special type of photoluminescence spectroscopy, researchers at the University of Regensburg in Germany were able to observe nonlocal effects in biexciton emission. Nonlocal effects are a quantum phenomenon in which two particles interact without being in direct contact. In their experiment, the team was able to observe a correlation between the emission of two biexcitons that were separated by several nanometers. The team believes that these nonlocal interactions can be used to control the emission of biexcitons, which could have a major impact on the development of quantum information processing and optoelectronics.
