...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.

1. What is quantum telecloning?

Quantum telecloning is a process in quantum mechanics where scientists create remote copies of laser light by teleporting the quantum state of a photon from one location to another.

2. How is quantum telecloning different from regular cloning?

Quantum telecloning involves the transfer of quantum information, which is impossible to do with classical cloning. Regular cloning creates identical copies of an object, while quantum telecloning creates identical copies of the quantum state of an object.

3. What is the significance of quantum telecloning?

Quantum telecloning has significant implications for quantum information processing and quantum communication. It allows for the remote transfer of quantum states, which can be used for secure communication and quantum computing.

4. How do scientists create remote copies of laser light through quantum telecloning?

Scientists use a combination of quantum entanglement and quantum teleportation to transfer the quantum state of a photon from one location to another. This allows for the creation of identical copies of the original photon's quantum state at a remote location.

5. What are the potential applications of quantum telecloning?

Quantum telecloning has potential applications in quantum communication, quantum cryptography, and quantum computing. It can also be used for remote sensing and imaging, as well as for studying the fundamentals of quantum mechanics.
