Beam me up ... Quantum teleporter breakthrough: (PhysOrg.com) -- Researchers have achieved a breakthrough in quantum communications and computing using a teleporter and a paradoxical cat.

The breakthrough is the first-ever transfer, or , of a particular complex set of quantum information from one point to another, opening the way for high-speed, high-fidelity transmission of large volumes of information, such as keys, via quantum communications networks.  The research was published in the April edition of the journal Science.  Teleportation – the transfer of quantum information from one location to another using normal, "classical" communications - is one of the fundamental quantum communication techniques.  The cat in the equation was not a living, breathing feline but rather "wave packets" of light representing the famous "thought experiment" known as Schrodinger’s Cat. Schrodinger’s Cat was a paradox proposed by early 20th century physicist Erwin Schrodinger to describe the situation in which normal, "classical" objects can exist in a quantum "superposition" - having two states at once.   link
