Why this matters: new research or scientific developments with potential real-world impact.
An international team of researchers, including scientists from Paderborn University, has reached an important milestone on the path toward a quantum internet. For the first time, they successfully teleported the polarization state of a single photon from one quantum dot to another that was physically separated. In simple terms, this means the properties of one photon were transferred to another through quantum teleportation.
This achievement is a key step for future quantum communication networks. In the experiment, researchers used a 270m free-space optical link to connect the systems. The findings have been published in the journal Nature Communications.
At Paderborn University, doctoral and postdoctoral researchers spent about ten years working on optical measurements, data analysis, and evaluation. During this time, Professor Klaus J ns's group collaborated closely with a team led by Professor Rinaldo Trotta at the Sapienza University of Rome.
