Experimental quantum teleportation
TL;DR: In this article, the authors demonstrated the feasibility of quantum teleportation over arbitrary distances of the state of a quantum system by using a measurement such that the second photon of the entangled pair acquires the polarization of the initial photon.

Quantum state transfer and entanglement distribution among distant nodes in a quantum network
TL;DR: In this paper, a scheme to utilize photons for ideal quantum transmission between atoms located at spatially separated nodes of a quantum network was proposed, which employs special laser pulses that excite an atom inside an optical cavity at the sending node so that its state is mapped into a time-symmetric photon wave packet that will enter a cavity at receiving node and be absorbed by an atom there with unit probability.

Ultra-bright source of polarization-entangled photons
TL;DR: In this paper, a source of polarization-entangled photon pairs has been provided that is more than ten times brighter, per unit of pump power, than previous sources, with another factor of 30 to 75 expected to be readily achievable.

Quantum repeaters based on entanglement purification
TL;DR: A scheme is presented that allows entanglement purification over arbitrary long channels and tolerates errors on the percent level and requires a polynomial overhead in time, and an overhead in local resources that grows only logarithmically with the length of the channel.
