- Quantum Mechanics Discovery Could Make Current Encryption Obsolete
According to quantum mechanics, small magnetic objects called nanomagnets can exist in two distinct states (i.e. north pole up and north pole down). They can switch their state through a phenomenon called quantum tunneling. When the nanomagnet switches its ...

- Atomic Coilgun Experiment Reveals Most Atoms Can Be Cooled And Stopped
Stopping and cooling most of the atoms of the periodic table is now possible using a pair of techniques developed by physicist Mark Raizen at The University of Texas at Austin. Raizen stopped atoms by passing a supersonic beam through an “atomic coilgun” a ...

- Mercury Versus Aluminum: The Race For The World's Most Accurate Clock
An atomic clock that uses an aluminum atom to apply the logic of computers to the peculiarities of the quantum world now rivals the world's most accurate clock, based on a single mercury atom. Both clocks are at least 10 times more accurate than the c ...
