There's something I don't quite understand about quantum entanglement and I'm hoping someone here can put me right. When I first heard about the Aspect experiment, I thought that it had to open the way forward for faster-than-light information transfer as follows:

Bob is on Earth and Alice is on Saturn. On Earth, Bob sets up his equipment to entangle photons, of which one half get sent to Alice. The other half stay on Earth but are effectively trapped by a cunning set of mirrors.

A few hours later, Bob checks his watch to ensure that the photons are about to arrive at Saturn. Bob then writes a message in binary to Alice. He dooes this by either measuring the x-axis spin of the first photon, or not observing it at all. He then repeats with the next photon etc.

On Saturn, Alice has a equipment setup for measuring the y-axis spin of the photons she's received. Now, either she can make a measurement or she can't - in the exact same sequence that Bob has been observing / not observing on Earth. So effectively she's receiving Bob's binary communication. And rather than travel at light speed, hasn't the binary code travelled instantaneously??

Can anyone shed some light on this?

[Don't get me wrong - I don't think I've discovered FTL information transfer or anything, I just want to correct my deficiency in understanding quantum entanglement and relatvistic effects?]
