London, Oct 15 : Using cheap lenses like those used in CD players, scientists have devised a new way to collide individual photons and atoms, which may revolutionise quantum networks, making them cheaper and easier to build.
Collision of single atom with a single photon is vital for operating many prototype quantum communications methods, including quantum networks and sending data using "spooky action at a distance".
The new technique uses cheap lenses to transfer data between light and matter.
And, according to physicists from Singapore and Germany, the new method that Quantum communications offers theoretically unbreakable security by encoding data into the quantum characteristics of photons.
