Quantum entanglement demonstrated

PORTLAND, Ore. — The National Institute of Standards and Technology (NIST) said it has demonstrated what it claims is the world's first entangled atoms that could be used to communicate information nondestructively.
By creating multiple pairings of entangled atoms, NIST scientist Dietrich Leibfried was able to transmit quantum data and verify its reception from one pair without destroying the information in the other pair...

First Quantum Teleportation Between Light and Matter

The concept of quantum teleportation - the disembodied complete transfer of the state of a quantum system to any other place - was first experimentally realised between two different light beams. Later it became also possible to transfer the properties of a stored ion to another object of the same kind. A team of scientist headed by Prof. Ignacio Cirac at MPQ and by Prof. Eugene Polzik at Niels Bohr Institute in Copenhagen has now shown that the quantum states of a light pulse can also be transferred to a macroscopic object, an ensemble of 10 to the power of 12 atoms (Nature, 4 October 2006). This is the first case of successful teleportation between objects of a different nature - the one representing a "flying" medium (light), the other a "stationary" medium (atoms). The result presented here is of interest not only for fundamental research, but also primarily for practical application in realising quantum computers or transmitting coded data (quantum cryptography)...
