Theoretical physicists from Lancaster University in the UK have designed a nanomotor that operates by a novel mechanism: an electron wind.


Physicists Store Images in Vapor

June 23, 2008 | User rating: 4.5 / 5 after 93 vote(s) | User comments: 4

Books are written on solid pieces of paper for an obvious reason: the atoms in a solid don’t move around much, keeping the words and pictures in place for centuries. Trying to store letters and images in a ...


Researchers Suggest Quantum Dots as Media for Teleportation

June 21, 2007 | User rating: 4.3 / 5 after 135 vote(s) | No comments yet

According to recent research, tiny clusters of atoms known as quantum dots may be excellent media for quantum teleportation, a physics phenomenon in which information – in the form of a quantum state, a very specific mathematical ...
