Photon Pair Coupled in Glass Fiber
Trachman writes: Austrian scientists have discovered a way to couple photon pairs. When two identical photons are coupled and the phase of one is changed, then thanks to the magic of quantum mechanics, the phase of the other photon also changes (abstract). Scientists predict this can advance quantum optics and quantum computations, taking us a step closer to having data transmissions secure from the nosy agencies of the world.
If any of you have expertise in this area, could you share your thoughts on the essence of this discovery and its associated potential practical applications?

Actually, it is even worse: "quantum modulation" is complete BS as networking technology and cannot scale to any real-world WAN networking, except on dedicated links. Why this nonsense gets touted every time is a mystery to me. In addition, what was done so far on dedicated links got broken. It is also not needed at all, as it is so slow that all you do with it is transfer a symmetric encryption key and then you use a conventional VPN. The key exchange is not a vulnerable part of a VPN link, at least if done right. So, in practice, this stuff does not scale, cannot be routed and is not increasing security anyways.
As to privacy being dead, that is a completely unrelated issue, and it is untrue. Strong encryption works. You do have to use it and you do need to invest at least a few days to find out how to use it right, this is not a "single click" problem. (Well, almost nothing is a "single click" problem, but people are stupid and believe the defective things they get delivered as "single click" would actually be beneficial.)
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.
we all made a conscious decision on that? I must have missed that somehow. Privacy is not dead. There is always something that can be done to ensure good enough level of privacy that also allows good enough chances to catch criminals. The current violations of privacy are not used to do even that but serve the powers that be. And that needs to change.
We don't get to decide. There are no serious privacy oriented options left in the marketplace. Privacy is about as hopeless as buying stuff not-made-in-China.
However, if you find that to be offensive, feel free to create misleading information to poison the various databases about you. The nice thing about companies collecting and reselling information about everyone is that they're so gullible. Just be reasonable enough that the new data doesn't get flagged and omitted. If you're a "Fry Technician" at a Fortune 500 company's franchisee, you may want more than one hop between now and your aspiring Bruce Wayne persona.
Depending on how much free time you have, or how much you just like to game the system, you can do things from provide grossly inaccurate income information to those that ask, to having one or more businesses (or hobbies looking like businesses), or creating new people. The easiest, legal way to create fictitious people is "authorized users" on a corporate credit card account. Anyone willing to pay a yearly fee can open a corporate account, then add anyone they want with little more than a name. As long as you use your fake people for legitimate transactions and pay your bills, there's nothing illegal about it.
Back on topic, hopefully developments like this can later be turned into more secure communication technologies that can be used after the advertising&data-merchant economy collapses.
