So there's an absolutely amazing, vitally important physics research paper just published entitled "Quantum Encrypted Information Sent Over An Eight Node, Mesh Network" by M. Peev et al (sic).
According to this site, it's published in the New Journal of Physics, 11, 075001 (37pp), DOI: 10.1088/1367-2630/11/7/075001.
Well first, as of today, that particular DOI doesn't appear to exist and nor does page 075001 et seq. of the New Jornal of Physics, which is published by the Uk Institute of Physics (IoP). Nor does any preprint exist - at least not that I could find. There is this on the arXiv.org server. M Peev seems to be there as one of the authors, but it's one year old and anyway doesn't give the "New Journal of Physics" as the destination journal. So just where is "Quantum Encrypted Information Sent Over An Eight Node, Mesh Network"?
It seems that some physicists are so desperate to hype their research that they are becoming like politicians - bad politicians at that - and making claims that something exists before it's actually available for scrutiny. I don't think Isaac or Albert would have done this. Tut! Tut!
