Quantum Telecloning: Scientists Create Remote Copies of Laser Light

[Ivan Seeking]

...The scientists have succeeded in making the first remote copies of beams of laser light, by combining quantum cloning with quantum teleportation into a single experimental step. Telecloning is more efficient than any combination of teleportation and local cloning because it relies on a new form of quantum entanglement - multipartite entanglement.[continued]

The paper is http://prola.aps.org/searchabstract/PRL/v96/i6/e060504?qid=cd1ed767723909f4&qseq=1&show=10" (links to abstract - sorry Ivan but the physorg write-up is awful)

and it is available for free as an e-print at arXiv /quant-ph:
http://arxiv.org/PS_cache/quant-ph/pdf/0507/0507240.pdf"

A very interesting development, I'm yet to read the paper (need more coffee for that). Anyone who's new to the subject of multipartite entanglement, I recommend the very recent review by Eisert and Gross:

Do you have Acrobat Reader installed? (it's free). Then clicking on a pdf will open it up automatically for you.
