So, the speed of light wasn"t breached?

What's to prevent sustaining quantum entangled pairs at seperate sides of the globe by synchronization and then looping them with repeaters?

I was a bit unsure on the speed of light being breached or not as well. In one spot early in the article it mentions that it can't be breached, but then later in the article it makes it sound like that by using the synched lasers, they were able to entangle far away particles, which can transfer information instantly (faster than the speed of light presumably if they are far enough away).

Is it me or this definition of a femtosecond gibberish?

(a millionth of a billionth of a second, or 10-15 seconds),

Which is it? 10-15 seconds or that tiny tiny tiny slice of time?

They are the same thing. It means 10^-15 seconds, which is:
0.000000000000001 s. It is a ridiculously small amount of time.

It is the same as a millionth of a billionth of a second.

sounds like an april fools joke to me

For some explanation of why the speed of light speedlimit was not breeched you might want to take a look at Colin Bruce's book: Schrodinger's Rabbits.

It does a decent job of explaning entanglement and how it works.Definitly worth the read! Cheers!

After reading this article, and similar prior articles, I have not seen anyone say how
much information was passed. I mean, how many bytes?

Also, how do the researchers know it actually went from one point to another?

Thank you very much Ian!

There are no stupid question but I was darn close.
I will know that format for 10**-15 from now on.

Thanks again

My understanding is that the speed of light is obeyed and
yet sidestepped as it were where the frames of references
are not entangled but they are. Or they are entangled but
they are not, as you wish.

Michael Thomas published on his website 2 years ago detailing entangled particle communication along with entangled particle holographic optical nanostorage. Its interesting that the chinese and others claim this as their work, probably visiting his website many times to get their ideas correct before publishing.

the speed of light is not breached as long as multi-dimenional space is taken into consideration.

string theory might be another variant of the entanglement thought.

For those of you wondering whether the speed of light was breached or not, here is clarification for you. Quantum entangled particles "exchange" information instantaneously (faster than the speed of light). Entanglement swapping, discussed here, carries the cost because the generation of entanglement at each stage is limited by a finite probability (thus preserving fidelity) and all stages must be entangled simultaneously for transfer. A collective atomic state is created from forward-scattered Stokes radiation (at the speed of light), implying communication varies as the square of the distance. Hope this clears it up for you.

I would carefully examine these results,
only after being PEER-REVIEWED by
reputable physicists.

Remember how the Chinese scammed
us (scientifically defrauded) on
those "incredible" results in genetics.

FYI:

After synchronizing the clocks to 2 femtoseconds accuracy, then moving one of the clocks a few hundred feet away, wouldn't just the moving of that clock cause time to slow down just a little for that clock, due to Einstien's theory of relativity, and cause the acuracy to be maybe a few tens of femtoseconds off? At any rate, I would suggest moving the faster of the two clocks.

In the measurement of the nature of the speed of light scientists forget the entanglement effect between the quantumn wave/particles (...ons) and atoms . This effect synchronises the constance of the speed of light . As a matter of fact in the two split experiment the entanglement between onòl one Q. wave (bidimensional both in space and time) and the atom of the two fenditures , generates two photons and two Q.bits . The generated photons coming out can be seen by interference effect. See Paolo Manzelli writings in www.wbabin.net .
