Physicists at the University of Vienna and the Austrian Academy of Sciences have successfully
transmitted quantum states between La Palma (from the Jacobus Kapteyn Telescope) and Tenerife,
over a record distance of 143 km. This experiment provides the basis for a worldwide information
network, in which quantum mechanical effects enable the exchange of messages with greater security,
and allow certain calculations to be performed more efficiently than with conventional technologies.
In such a future 'quantum internet', quantum teleportation will be a key protocol for the transmission
of information between quantum computers.
