It depends on what you want to transmit. Of course, videoconferencing is kind of out of range, but a lot of very interesting things were done in the age of 14.4kbps modems. In any case, most applications are likely to be of the plaintext type: diplomatic memos, banking info and the like.
Which is why quantum cryptography uses a one-time pad as an encryption algorithm which, coupled with quantum key distribution, becomes secure. It's not like OTPs are rocket science. It's the QKD part that's hard.
How much is a 500Gb drive worth nowadays? 150$? So your OVER NINE THOUSAND drives are worth about, hum....1.35M$. CERN has a budget of about 5B$.
It's the speed at which data is coming that's a problem. Not the total amount of data.
Mod parent Insightful. This ain't funny. It's a one-line proof by contradiction that the experiment won't work. Unless there is no free will, in which case.....
...looks at you in the eye and waves his hands......

Whatever the amount of payment, I think that they are allowed to check your credit history. In particular, they are allowed to refuse to sign a long-term contract if you don't have any credit history. But I think that you're right, once you get past that (maybe by having someone back you up), they have to accept cash.
IANAL, of course.
I actually had the inverse problem some years ago. My landlord got burned by bounced checks (not from me), so he accepted nothing but cash. Every month, I had to go to the ATM and carry large amounts of money in the street, which I didn't like. I can't imagine not using the banks nowadays, I think you are underestimating their usefulness.
Very easy. We do not go faster than light. Once, a journalist came to see me for some local TV station. He asked: "So, how do you manage to go faster than light?". We answered: "Actually, we can't go faster than light. We still need to have a classical signal on the side. The classical signal doesn't encode information, but we still have to wait for it to arrive otherwise we can't retrieve the information". Guess what was the headline the following morning?
Yep, "Local scientists manage to communicate faster than light."
By the way, it's not that hard to test. Three kilometers at the speed of light is 10 microseconds, which is still kind of fast but well within the range of today's clocks.
It is teleportation of information, not of matter. We scientists define teleportaion as "moving something between point A and point B without ever being in between", which is different from the Star Trek "transforming matter in energy and into matter again". It does get us a whole lot more funding than if we had called it something unfashionable like "Communication through entanglement".
By the way, IAAT (I am a teleporter). I don't get to work work in the Canaries though. It's a shame.
Because US missile bases in Europe threaten Putin?
Honestly, the rethoric is more threatening than usual, but where did you expect the Russians to point their weapons at?
I don't know what size their 'pipes' are, but it's more than just 5 ethernet connections. This is the place where the web was invented, remember. And they have truckloads of money. Anyone who can build something that generates this amount of data will have thought of having enough throughput for it, trust me.
The ring is 17 miles. There are four detectors at different points on that ring, each of which is of course much smaller. The photos in the article show the detectors.
"A patent for a method to distinguish between obvious, non-obvious and not non-obvious patents and/or patent applications that consists in asking oneself if someone properly trained in the field in which said patent is filed into would have come up with the same idea if only presented with the problem in question, and also a method of research that consists in finding prior art for said patent."
Ah-ah! Now you can't say my patents are invalid without violating this other patent! Catch-22, you're screwed!
For AC, I can understand that the costs dropped, but for exit lights? You save something like 1 watt from it, and you only need to use a camera and a processor to do this! Anyone know of a camera that uses less energy than an emergency light?
Personally, if I put a dilute gas in a vacuum chamber, apply a voltage and see a small ball of fire, I think plasma. Why is this not just a plasma? How do we know it's fusion?
And what is a "hyperbolic chamber"???????
Note: creating a plasma at 17 years old in a garage would still be very cool. Maybe not slashdot-front-page cool, but still cool.
Once you detected the spin change once, the particles are not entangled anymore. This means that you cannot look at it continually and wait for change. It's the "it's not really really there until you look at it" property of Quantum Mechanics.
There will be no signalling. What the researchers are looking for is a relation between two entangled photons, but the relation can only be found by comparing the results after.
To make a crude analogy, imagine I am sending you a bunch of random numbers, and that by altering something in my lab I can change the values of these random numbers. Then, afterwards I can tell you "look at random numbers #31,57 and 68, they form a message". The manipulation I made is instantaneous, but in order for you to get information out of it, I have to tell you where to look for via a classical communication.
This might not be very clear, maybe Wikipedia is clearer.
In short, what they are trying to do is a nice experiment, and it should work, but it does not mean you can signal backwards in time.
Considering light IS electromagnetic waves and that what was photographed WAS an electric field (or rather the disturbance it caused, but the effect goes at the speed of the field, not the disturbance), then.........at 99.997%*c, that light was awfully slow.
Note that light only goes at the "speed of light" in the vacuum. In anything else, it's slowed down.
You still know what the original state is. If you put a cat in a box, and then you don't look in the box, you still know there was a cat in the box. When we say "the original gets destroyed in the process", it means that if we try to re-measure the original qubit after teleportation, then the information is not there anymore because the supporting atom/photon/spin state has now been randomized.

Considering that opening Excel or Word takes up to 10 secs on a 1GHz computer, that's not a very good benchmark.
Oh, you meant the time it should be taking to open a reasonably designed word processor? Sorry, my bad.

Only the US maintains an embargo towards Cuba. It never asked the Security Council to do so.
Yeah, I know. But rent was cheap, and I didn't "officially" know.....

Would that be 0.84 Internet per forthnight? Or 1 kiloLibrary per Congress session? How much in tubes?
Honestly, is anyone surprised? Why would you buy a microsoft product for something that just begs to be DRM'ed?

In what french expression exactly is it a show of respect to use "bâtard"??? I cannot think of one.
