How will the NSA intercept this then?

Scientists teleport quantum information across the room

Researchers working at TU Delft's Kavli Institute of Nanoscience in the Netherlands claim to have successfully transferred data via teleportation. By exploiting the quantum phenomenon known as particle entanglement, the team says it transferred information across a 3 m (10 ft) distance, without the information actually traveling through the intervening space.

"Entanglement is arguably the strangest and most intriguing consequence of the laws of quantum mechanics," said the head of the research project, Professor Ronald Hanson. "When two particles become entangled, their identities merge: their collective state is precisely determined, but the individual identity of each of the particles has disappeared. The entangled particles behave as one, even when separated by a large distance."

As electrons in an atom exist in orbits around a nucleus – like the way that the Earth spins on its axis – electrons also have "spin." When two electrons are entangled (that is, when they interact physically) and are then forcibly separated, the spin information on each becomes opposite to the other; they are essentially turned into mirror images.


However – and this is the bit that Einstein found "creepy" in his rejection of the entanglement theory – when one of the entangled electrons has its spin direction changed by some means, the other electron immediately reverses its own spin direction. The distance in the Kavli Institute tests was 3 m (10 ft) but, theoretically, this distance could have been hundreds of light years.

You could use this method to send stuff to Keplor-10c.

Very exciting!

I imagine it would be possible to detect if this was intercepted anyway? I remember Simon Singh talked about "Quantum Money" in his code book to make the point that any attempt to observe "qubits" would result in a faulty transmission as they'd be destroyed.

Let's hope it takes off.

Look forward to it, we'll be able to tell where Quantum P0rno is but never where it's going...

p to the e

You'll be able to state at what position to start the porno or at what speed to play it at but not both!

hmmm

They'll intercept it at either end of course. There's too many naive people that think that cryptography and protecting traffic from interception is the be all and end all of security - signs on all these searches for "unbreakable" communication protocols.

None of this matters if your router has a capturing device. Or your PC has a trojan copying all your traffic. Or your laptop is taken from you at a border. Or you are "encouraged" to hand over your passwords.

I'm inclined to agree hmmm but I don't see any reason to throw the baby out with the bath water - an encrypted laptop seized at the border for instance won't do law enforcement much good unless they can scare you into handing over the password with unjust jail sentences.

Speaking of routers, have you heard of dd-wrt ? I want to install it on home router but my better half won't let me.

BULLRUN and QUANTUM INSERT has us all.. and no, these are not random words from barbaric dreams, nor our secret grandmother recipe .. these are very sophisticated and highly funded programs, which NSA uses in order to open doors on pretty much any electronic mean.

BULLRUN, is all about buying developers and having them insert malicious code or backdoors. This would not have to be a very obvious one, but could also be a "flaw" - such as the one of cryptographic library SSL was (HeartBleed bug) - where it would leak info and private memory data to a direct attacker.

QUANTUM INSERT is about implants, where NSA would use zero-day vulnerabilities or malware for gaining access to computers. Essentially, doing the very same job that criminals do, but under the excuse of "world peace, stability and security".

What an irony of it all. Promoting insecurity and violation of privacy, in the name of security...

Hi bd101,

I've heard of the programs but I see that as inspiration to update our existing security practices, not to throw up my hands in despair and concede the NSA have access to all our private data.

The Tor network is an excellent case in point - the NSA have been unable to compromise the overall structure of it (with the exception of a well publicised Firefox exploit which has since been patched) so they've been focusing on targeting the endpoints (keylogging, rubber hose crypto etc.)

Do you believe that confidential communications still can't be achieved, for instance via using Torchat with OTR messaging?

Numerous tor end-nodes are already compromised. While it is quick and easy to set up, I would not depend on it as a "golden ticket" to anonymity.

Surely that's only an issue if you make use of exit nodes though? If you kept your communications within the tor network e.g. By using bitmessage's onion domain to exchange e-mails encrypted with gpg, I'd say that's sufficiently robust to prevent your messages being intercepted through DPI etc. - Of course you'd still need to keep your private key safe and connect to the tor network securely by using a private bridge - Snowden himself said strong encryption still does work if we're able and willing to use it.

You're absolutely right - I didn't read your original post all the way to the end, so my misake there.

Thanks CathalC2011 I wasn't being horrible, just wasn't sure we were on the same page.

In a more general sense end points can encompass your own computer - tor can't protect against 'evil maid' attacks nor can it protect any files you've downloaded via the network.

Personally I'm a fan of using the TAILS Live CD with an encrypted USB Stick for the ultra secret stuff but of course you have to be very careful about saying you've come up with a perfect way to keep your data safe.
