Quantum leap in communications?

Until a bird flies in the path of LOS and instantly fries or disrupts the communication. lols
 
If they can quantum entangle stuff already, why bother with primitive stuff like light beams?

Just get 2 pens entangled, write something on a page, and the other one will do exactly the same.

Or just do it with logic gates in a computer, type something on one and it appears on the other one as well..
 
Jees, what's with all the negativity. I'm just glad to hear that some kind of research is actually still happening in SA and that they're getting results.
Good work. They have my support.
I'm sure they're way ahead of any dumb negative remark someone can come up with here. If not, then kudos for actually DOING SOMETHING cool.

Yes, this is me, taking the comments waaay too seriously... ;)

Flying qubits...thats quite a long way off still. Creating *any* kind of qubit is bleeding edge right now. And thats in full lab settings nevermind flying through the air.

Awesome that SA is participating though....its far fetched right now, but its only a matter of time until all that becomes feasible. And if it does SA should be in the middle of it :)

Quantum cryptography was successfully hacked last year: http://www.nature.com/news/2010/100520/full/news.2010.256.html

One implementation of it was hacked. The underlying mechanism is still sound.

Because they can't fit a couple tons of lab equipment into your cellphone. And if they could it would still not be any use since its single bits we are talking about.
 
'Free space quantum communication'

sounds like one of those phrases that creates hype, gets lots of investments, then disappears never to be heard from again...

Who said anything about cellphones? It's for transmitting secret information, between buildings, with 2 lasers aimed at each other, thus needing Line of Sight.

You fail at understanding entangled states.
 
To my little brain this sounds like not just 'bleeding edge' but 'theoretical bleeding edge.

Unfortunately, thanks to dishonest kooks like Deepak Chopra and the fsucking homeopaths constantly using the term so dishonestly just to peddle their moronic quackery, when I hear anything is 'quantum' these days, if it's not a published quantum physicist speaking I assume it's just more BS.

I assume Dr Roux is the real deal, being MyBB and everything... :)

In the words of the brilliant Richard Feynman, if you think you understand quantum theory, you don't understand quantum theory.
 
I can just imagine...

*Phones Telkom*

You: Yes, hello, my Quantum-Line is down *Provide relevant details*

Them: Unfortunately we are currently having an issue with our quantum-receiving array. You can expect the problem to be fixed within the next 6 months.

You: ... Thanks....

Why did he fail? They are just opposite that is all. And a serious mission to create in a lab and that is an understatement. But in theory I reckon it would be instant <1ms latency communication to Mars even :D
 
Nice one, I just wonder how iffy these laser beams would be in say a city or hilly environment. I have never really been a fan of line of site, too much that could get in the way.

Anyway good to see SA is doing something that actually is on the cutting edge of tech. Of course then there is Telkom, also on the cutting edge of tech, and to prove that I quote a Telkom "engineer" when he was trying to tell me why I have to put up with a severely crippled ADSL line: "Our scientists have determined that home users do not need more than a 384 kbps ADSL line, so they have designed the DSLAM you connect to to only handle that." :sick:

All I can ask of the real scientists like Dr Roux: If you guys ever get this thing working, for the love of G, DO NOT let Telkom get their hands on it. ;)

Harry Potter has done that already -- he is the master of it :erm::D
and
His creator will probaly end up the winner in terms of "money-in-the-bank"

See -- it is easy to understand Quantums

:whistle:

:D
 
Read an article about this in "ScienceScope" CSIR quarterly publication .. Defence and Security .. using twisted light in info systems. Same bloke.. very interesting
