Making teleportation 'fuel-efficient' Beam me up Teleportation,
so familiar to science fiction fans, may have come a small step
closer thanks to research by a team of physicists in the United
Kingdom. Over the past decade, scientists have shown that the
powerful connections generated between particles through the
quantum law of 'entanglement' could allow information to be
teleported. Now, PhD student Sergii Strelchuk from the
University of Cambridge, and others, have described a scheme
that would make such teleportation more practical and efficient.
In their paper, published in the journal Physical Review
Letters, the researchers explain that previous teleportation
protocols have fallen into one of two categories. Some only send
scrambled information requiring correction by the receiver,
while more recent "port-based" teleportation schemes don't
require a correction, but need an impractical amount of
entanglement, which would destroy the entangled state. In the
new research, physicists provide a theoretical s
