Instant teleportation

Article Abstract:

Quantum physicists are looking for ways to make teleportation possible. Teleportation is based on the idea that a physical object is equivalent to the information needed to construct it. In a certain sense, teleportation, which is sending a copy of an object to a receiver while leaving the object at the point of transmission, is possible within classical physics. This is exemplified by the facsimile machine. However, reducing the scale of reproduction eventually leads to violation of the uncertainty principle of quantum mechanics. To solve this problem, quantum teleportation makes use of the concept of 'entanglement.'

Illuminating entanglement

Article Abstract:

Massachusetts Institute of Technology educators have made Richard Feynman's sequence of demonstrations of wave-particle quality and the uncertainty principle more feasible in the laboratory. Their experiment does not use two slits but also features an atom beam split into two parts moving along different paths and showing an interference pattern upon recombination. A unique feature is that interference is restored as separation further increases.

Deterministic quantum teleportation of atomic qubits

Article Abstract:

Unconditional teleportation of massive particle qubits using atomic ions confined in a segmented ion trap, which aids individual qubit addressing, is described. Quantum teleportation provides a means to transport quantum information efficiently from one location to another, without the physical transfer of the associated quantum-information carrier.
