Realizing quantum bits

In computers of the future, information might be stored in the form of quantum bits. But how can a quantum bit be realised?

Lasers could make hard drives faster, simpler and higher density

(Phys.org) —Researchers at the University of California, San Diego have discovered that for a wide range of ferromagnetic materials the direction of magnetization can be completely controlled by polarized light without ...

Controlling skyrmions for better electronics

Physicists at the University of Hamburg managed for the first time to individually write and delete single skyrmions, a knot-like magnetic entity. Such vortex-shaped magnetic structures exhibit unique properties which make ...

Smallest vibration sensor in the quantum world

Carbon nanotubes and magnetic molecules are considered building blocks of future nanoelectronic systems. Their electric and mechanical properties play an important role. Researchers of Karlsruhe Institute of Technology and ...

Manipulating magnetic forces with light

The magnetic forces in magnetic materials like iron can be rapidly manipulated with light. Rubicon Researcher Johan Mentink, together with Martin Eckstein from the University of Hamburg CFEL/MPSD, has theoretically demonstrated ...
