The weird quantum world: Entanglement – 'spooky action at a distance' – causes the properties of two atoms to be linked even when they have no contact with one another.

Once the two ions were entangled, the researchers took a measurement of ion A. Because ion A and ion B were entangled, this forced ion B to embody the initial unknown quantum state of ion A. The team then applied a microwave pulse to ion B to recover the original state of ion A.
The researchers report that atom-to-atom teleported information can be recovered accurately 90 per cent of the time – a figure they hope to improve.
Quantum repeaters
Monroe said that their set-up could one day have a use as a 'quantum repeater' – these tackle the problem of generating a signal by temporarily storing the state of a photon. New photons with the same state are generated at each repeater propagating the signal.
"Our system has the potential to form the basis for a lage-scale 'quantum repeater' that can network quantum memories over vast distances," added Monroe. Without quantum repeaters, long-distance quantum communication would not be possible.
"This experiment is an important step toward the realisation of quantum repeaters," wrote physicists M. S. Kim and Jaeyoon Cho of Queen's University in Belfast in an accompanying commentary in the same issue of Science. "With the recent experimental advances, the theoretically presumed quantum paradoxes are slowly revolutionising information technology."
entanglement by dark-information
In my study, published on my website www.darkfieldnavigator.com, I reveal that entanglement is produced by a duonistical state of dark energy and dark matter. In this so called 'darkfield', entanglement is defined by 'dark-information' with speeds far beyond the lightspeed. There is a scientifical team in the university of Geneva (Nicolas Gisin and colleages), who measured a statistical possibility entanglementspeeds of 10 to 10000 times the lightspeed. According to my darkfieldtheory those speeds are located in a layer below the quantummechanics. According to my darkfieldtheory it means that we live at the edge of the event-horizons of an enormous amount of Planck holes, which evapourate in a flash. The 'dark-information' is released by the hardly non-existing Planck holes. So one can consider the universe as an enormous amount of hardly non-existing Planck holes producing 'dark-information' to recalculate the quantumdynamics. My darkfieldtheory is new physics, revolutionary and theoretical prepared for peer-review in an interactive way by the internet. This is because the institutional physics-reviews neglect progress of clear new ideas.
I recommend you to write an article for me on 'cosmos'-web about my darkfieldtheory. Please inform me, if you do so.
