Scientists eye safe communications by slowing down mild

Scientists eye secure communications by slowing down light

We have already seen what fiber optics can do for web speeds, and it appears just like the medium might be used for quantum communications too. See, as EurekAlert tells it, scientists from the Vienna College of Know-how have found out a solution to modify the fabric so it may be used to regulate the velocity of sunshine. The researchers efficiently grafted cesium atoms to the fibers, permitting them to sluggish mild down from its typical 671 million MPH tempo to round 112 MPH (one hundred eighty KPH). The researchers have been capable of deliver the sunshine to a whole cease after which restart it later, too — one thing EurekAlert says in a reasonably main step towards quantum web. It would be far more safe than what we have now at present as properly, provided that professor Arno Rauschenbeutel says that quantum physics at its very core permits for a connection between sender and receiver and anybody tapping in will not go unnoticed.
