(But I'm bracing myself for the smartass replies you might get. )
Reading the thread might have helped because we did discuss ~7 meter long photon wave packets earlier in the thread here. That's probably too large for the proposed experiment, but the point is, even though some photons are indeed small, doesn't mean all of them are too small.

I don't understand your response. If I thought the photon had only particle-like properties I wouldn't see any point in doing the experiment. The quantum wave function I posted earlier when I mentioned wave-particle duality relates wave-like properties which I'm also interested in:

A wave packet is not a photon. YOU CANT THINK OF A PHOTON LIKE A PARTICLE. WAVE PARTICLE DUALITY.
I am actually interested to see how wave-particle duality is expressed in the experiment, and I would like to see if the wave function influences where the photon is detected in this experiment as the double slit experiment also shows evidence of the wave function.

The fractional quantum hall effect in anyons but in a photon. Moving the laser mid-packet would have the same outcome as any other type of quantum mechanical measurement: the function collapses to either of its basis states. By "either of its basis states", i am referring to the collapse of the wave function to ket1 or ket0. In the case of a laser, ket0 is filtered out which leads to the coherent phase. "either" can turn into a menagerie of intermediate states depending on the length of the probe. So, at the new trajectory, it will collapse either of its bases. No matter how quickly you move the laser, you will never change the angle (change the frequency) of the photon.
By using a smaller probe (shorter time interval) for measurement, you will introduce virtual particle interactions. I think this could be legitimately described as "curving" the vector potential but the particles will only be manifest at their known energy quanta.

Hence the relevance of the quantum wave function.
Can't you define with quantum mechanics a time prior to the time the photon impacted the detector where the wave function probability of the position of the photon would show a 50% probability of being outside the source and a 50% probability inside the source?
Obviously both probabilities cannot be realized simultaneously, because if you measured the photon position, it would be one or the other, which means there's no violation of relativity with such a probability wave function. Right?
So, the measurement of a single photon would not he helpful. In order to measure the effect of the quantum wave function, just as in the double slit experiment, you have to see the pattern formed by many separate photon impacts on the detector to observe the wave properties of the wave function, and in this case, there is no relativity violation.edit on 1-10-2012 by Arbitrageur because: clarification

Obviously you've seen the double slit experiment, where one photon at a time impacts the detector. I posted such a video earlier in this thread. One photon impact doesn't make an interference pattern. Only lots of them do, by separate photons. What don't you get about this?

words like "seperate photon" make no sense in QM(atleast in the context you are.
Again consider the double slit experiment. The quantum wave function determines statistically how a large number of photons will interact with the 2 slits. Similarly, would the quantum wave function determine statistically how a large number of photons will interact with passing through the exit of a moving source?
Im intrigued by the first paragraph, but not sure I get it fully. can you elaborate

When the photon impacts the detector, if you know the distance from the source to the detector and how fast the photon traveled to get there, then if it traveled in air at 99.9% of the speed of light you can calculate when it would have been at the exit of the source. Since the wave function hadn't yet collapsed at that time, then we don't know exactly where the photon was, so we can only say what the probability was that it was in a certain position using the quantum wave function at the point in time when its most likely position was at the exit of the photon source.
