Teleporting Accomplished At An Atomic Level

Hogwash on the whole "teleporting people" nonsense angle of this article. A quantum state ain't a fly or a human body.

So at best we can now send Morse code dits and dahs (or up and down spins, rather) of quantum states across a distance at the speed of light. I wonder who will be the first to send a quantum "SOS"?

Gee, I covered this back in a 2007 news story (and back then it was old news).

Don't expect to be teleporting around the globe, but don't be surprised if your high speed internet connection (or similar) incorporates un-hackable and secure quantum teleportation of data in the future (a real application under development).

Somehow I'm doubtful that the governements of the world would ever let a truly secure connection they can't evesdrop on make it to the consumer level.

In other words, "spook agencies" won't like "spooky action".

Just because you cannot (theoretically) tap into a quantum state transmission line doesn't mean you cannot monitor the receiving end after the data is converted back to standard non-quantum electrical impulses.

As with weapon and armor development, each try to surpass the other thru development but nether one surpasses the other for very long.

True, but y'know....

I used to surf anonamized (is that the term?), and encrypt my email

Until I realized I didn't have anything to say worth protecting, and certainly nothing worth irritating the people we refer to.

as for the teleport - old news; who is applying for a grant?

Glossy coffee-table fluff. Where's the beef? This article is like an empty, gift-wrapped box. They lure you to their site with the promise of something interesting and then immerse you in mindless adverts once you get there. For example, try hovering your mouse over the "technology" link near the end of the article. The popup reads: "Try Matthew's Auto near Syracuse for affordable pre-owned vehicles."

This website is crap.

Subtracting photons from arbitrary light fields: experimental test of coherent state invariance by single-photon annihilation

A Zavatta et al 2008 New J. Phys. 10 123006 (10pp) doi: 10.1088/1367-2630/10/12/123006

This experimentally proved a theory (that dates from the 1960's and got the guy the Nobel) and will allow a tap in a Quantum Encrypted transmission. I knew this would happen eventually... but this was quick. This is for anybody who thought simple Quantum Encryption would actually be "unbreakable" forever.

This is what happens when marketing hype meets science (or any other discipline). They said Titanic was unsinkable, remember?

Even if quantum encryption were unbreakable, messages sent in this way can be corrupted so that the receiving end receives nothing but gibberish. Third-party decryption isn't the only hack, but it's the one the blinkered marketing types emphasize. Destructive interception - scrambling - can be just as valuable (if not more so in some circumstances), particularly if both the message content and its timing are critical.
