    The People's Daily reports the opening of the world's first, totally secure, quantum communications line. The line connects Shanghai to Beijing and some points in between.

    Guests attend the opening ceremony of the Jing-Hu, or Beijing-Shanghai,Trunk Line, in Beijing, capital of China, Sept. 29, 2017.

    The line also connects to the world's first quantum satellite which has been in operation for some months.

    WT this year: "True Christians bring honour to the Most High when they prayerfully consider the dangers of using worldly technology."

    WT in five years: "Are we not thrilled to see the World wide increase of secure downloads of Bible based literature? Certainly this is evidence of Jehovah's backing."

    Grin! Are you quoting our former loving brothers as evidence that YHWH or JESUS have sent the holy spirit to provide secure downloads?

    I'm not sure what they may mean when they use the term, 'secure downloads' , but my understanding of current 'in use' technology is that no current system is completely safe. (If I'm wrong, someone please correct me). Its possible their use of the term may hinge on so-called unbreakable encryption. If so further developments in quantum computing may end that possibility. (See: http://theconversation.com/will-superfast-quantum-computers-mean-the-end-of-unbreakable-encryption-64402 )

    Again as I understand the situation, there has been a lot of research around the world into the possible development of quantum technology for completely safe electronic communication.

    Back in June, Australia's government owned media group mentioned the successful development of a quantum satellite. Under the Heading - "Chinese scientists use satellite to smash quantum entanglement distance record" the report stated:

    "The experiment by a group of Chinese researchers, led by Professor Jian-Wei Pan of the Chinese Academy of Sciences (CAS), takes us a step closer to achieving instant, unhackable communication."

    This new quantum method of secure unhackable transmission uses light. The downloads of "new light" available via holy spirit to the GB seem to be subject to some pretty severe hacking attacks.

    Simply, the claim is that communications on it can not be hacked or intercepted. That's why there's been so much research effort focused on quantum computing and communications

    Supposedly, all present communications can be overheard if you have the right gear. (Think the USA's Pine Gap facility near Alice Springs in the NT). Any telephone conversation in Asia (or Australia) can be overheard. Of course, if its encrypted you may not be able to decode it, but (again its a claim) with the advent of extremely powerful quantum computing, most current encryption could be decoded. So a different approach will be required to provide secure communications.

    We're talking about some very complex stuff, and I admit I really don't understand it.

    An overview of it has been discussed on a web-site specialising in this stuff, and it also reports (on Sept 30) :

    "Earlier today, China's pioneering quantum satellite Micius facilitated the first-ever intercontinental video conference using a quantum communications network. The video call connected Chunli Bai, the president of the Chinese Academy of Sciences in Beijing, with Anton Zeilinger, president of the Austrian Academy of Sciences in Vienna, a distance of over 4,600 miles. It was the first real-world demonstration that showed that a global quantum internet is not only possible, but within reach. "
