...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.

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
