If you use a polarising filter, followed by a detector to detect only half of the photons arriving, then your are right.
However I did not say this. Certain kinds of crystal (calcite for instance) will bend the path of a photon based on its polarisation. So, wire up 2 photon detectors at different exit points from a calcite crystal, and all photons (minus random losses due to the material itself) will get through and be detected, both alignments..
>>>No, this is not the case at all. If you do not know which axis to measure on you destroy the entangled state. **Completely incorrect**. Quantum theory says that you'll get the entangled photons polarization will correlate to each other.** It doesn't matter** what axis you measure on. If this wasn't the case, well, there wouldn't be anything special about this facet of quantium physics, that couldn't be explained with classical.
>>The spooky effect is that you do see either a quicker or slower dropoff than the cos^2(theta) for polarizers with these entangled state, I can't remember which (quicker/slower).
If you took 2 polarisation detectors, each measuring one of the entangled pair of photons, then cos^2(theta) describes how often the two bitstreams will correlate. However, theta is the angle between the photon detectors... It has no dependence on the original polarisation the the photons are emitted. Indeed it can be shown the emitted photons **cannot actually have** a specific polarisation.
Take a source of entangled photons.. It could emit one photon at 0 polarised (for vertically polarised), and one at 90 for horizontally polarised, in a continuos random stream of.... lets also imagine that this set of emitted photons are a bit stream. H for 0, and V for 90. It could look like this
HHVHVVVHVHHVHVHHVVHVVHVHVH -> stream of Photons VVHVHHHVHVVHVHVVHHVHHVHVHV -> stream of entangled pairs
And lets finally say, that this emitter could be reset so the same bit stream could be sent time again. This is impossible, but, for the sake of argument, let say it could.
A detector at the other end, will detect if photons received are at 0 or 90, showing 'H' for polarised photons at 0, and 'V' for photons polarised at 90 So, the two received bit streams would be:
Nothing spooky so far?... Well, lets rotate the detector itself 90, so that photons arriving at 0, will be detected as 'V' and photons arriving at 90 will be shown as 'H'. The detector will continue to match the pair of photons, one as been a 'V' and one as been a 'H'., just the other way around.... Still no spookyness here.
Ok, rotate the detector so its set to 45, in between horizontal and vertical. The photons arriving at 0, will, at random, will have to choose, at random, a new polarisation. So, in classical theory, the bit streams should no longer correlate..... This is not the case.
Though the bit streams are different than they were emitted, yet they still correlate. This is the spooky part. the photon has to select H or V, when it gets detected. How is it possible that the entangled pair, 'knows' which orientation its partner was decided by its partner?
Its very weird. I personally think, that the partical we know as being a 'photon' or 'electron', isn't like a very tiny ball bearing traveling through space..... but, more like something else... If we think of particles having spin, and being able to detect them, then all this quantum weirdness appears.. Something else is going on. What that is, I have no idea, and neither does any one else..... But, quantum theory matches what we observe, it just doesn't make sense.
If my browser consumes a kilowatt of power, but renders a page in a millisecond.... then this would use less energy than one using 2 watts, but takes a second to render. The whole test is just wrong!, they should be calculating the energy usage, not the power usage.
Obviously, the record companies disagree with you..... why else would Apple have to negotiate, rather than just flick a switch to allow multiple downloads.
I guess, their argument is, if you damage a CD, you have to rebuy. You should have to do the same for digital downloads
...So, how come they want to negotiate with the music cartels?.... Whats in it for them, they're only after are hard earned money, with their rip off ipads/macs/music store... as we all know.
(/sarcasm!.... I'm actually an Apple lover... but, this is directed at all the haters that seem to frequent Slashdot these days).
So, say I work for Microsoft, and have a WP7 phone. Each nigh, while the misses is watching 'the biggest looser' on TV, I mess around with the SDK, and come up with a game..... which becomes a bigger hit than angry bird.....
And, then Microsoft, my employer, come and take 30% of the revenue?
The thing about a sharp knife, it looks like a sharp knife...
The thing about a trojan running on a phone, it looks like whatever the app maker wants it to look like, probably fluffy and cute and not at all like something that's going to hurt.
But... this type of hack will never get into the wild on the iPhone......or, if it was ever missed by their app vetting procedure, Apple could remotely shut it down anyhow.
Remind me not to get an Android phone, if this is the type of stuff hackers are going to be distributing soon.
