An experiment with "frustrated magnets" could help us to develop the first quantum computers




Scientists have made a step forward in the development of quantum computers.

In condensed matter, "frustration" is a phenomenon that involves sticking atoms in specific positions, unusual. The same phenomenon is described as a sum of inter-atomic forces that favor different structures, thus entering the conflict. This "frustration" create complicated structures and behaviors.

Frustrated magnets are a class of materials that similarly developing new features due to this phenomenon. Specifically, the magnets lose their magnetism at low temperatures. In an experiment conducted by researchers at Princeton University scientists have made a breakthrough proportions "could clarify the mechanism superconductivităţii high temperature friction-free electricity transmission".

The researchers wanted to see if frustrated magnets presents "Hall effect" that occurs when currents of charged particles in a conductor accumulate in one hand if you are in a magnetic field.

Given that frustrated magnets are not magnetic at low temperatures, observing the Hall would be an important advance in the field of computers and could lead to the development of quantum computers.

"Talking about the Hall effect for neutral particles is an oxymoron, a crazy idea," says one of the authors, Phuan Ong, from Princeton. However, the effect was observed.

"We are all very surprised because we work and play in a world classical non-quantum. May seem very strange quantum behavior and this is just one example of something that should not happen in reality is there, "added Ong.
