The exchange of a ‘secret key’ for encrypting and decrypting messages over a distance of 1,120 kilometres is reported in Nature this week. This achievement is made using entanglement-based quantum key distribution, a theoretically secure communication technique. Previous attempts to directly distribute quantum keys between two ground users under real-world conditions have reached distances of only around 100 kil...
In a complex bio-environment, does heavy ion transfer play a role? A study conducted by a team of researchers from the Institute of Modern Physics (IMP), the Institute of Applied Physics and Computational Mathematics, and Centre de recherche sur les Ions, les MAtériaux et la Photonique (CIMAP) in France reporting a new channel involving heavy N<sup>+</sup> ion transfer observed in a charged Van der Waals cluster ...
Newly released genomes from Neolithic East Asia have unveiled a missing piece of human prehistory, according to a study conducted by Prof. FU Qiaomei's team from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences.
New research by scientists at the Dalian Institute of Chemical Physics has shown, surprisingly, in the simplest, well-studied reaction, there is still uncovered mechanism. It leads to clear quantum interference and verifies again that Nature does "play dice".
Claims that the coronavirus pandemic originated in a laboratory in the Chinese city of Wuhan have no basis in fact, the head of the lab told Reuters, adding that there were still no conclusive answers as to where the disease started.
What is the origin of the famous interstellar object 'Oumuamua? How was it formed and where did it come from? Researchers from the National Astronomical Observatories of China offer a first comprehensive answer to this mystery.
