Cthugha thanks for your response, it's never late. I will need to read your reference. Also I'm not quite sure what you mean by single and two photon interference?
I'm pretty sure I understand now why the Walborn experiment must have coincidence counting and I'm relatively sure that same...
Unusual, it's true the walborn experiment does seem to be similar to the zeilinger one looking at it more closely. I think I understand what you and Jesse are referring to as the subset of total photons now. The subset of entangled photons "selected" or measured by the polarizer means their...
Jesse the quantum eraser experiment you have referenced is one of many possible ways to erase the which way information. In that experiment a bad design for FTL communication was chosen (good for simple path erasing). Look at Dopfer et al. The Heisenberg detector does not have this weakness...
If we take a Zeigler type of QE setup and somehow produce 100 nanoseconds worth of back to back to back photons so that there is thousands of them back to back in that 100 ns and send them off to NewYork and the entangled "pulse" to San Francisco (we produce them somewhere in the middle) we...
As far a FTL communication is concerned, this is an area of intrigue for anybody with a pulse and as a Quantum Physics student with a pulse I am very intrigued.
I challenge the notion that a photon pair in a singlet state for example cannot transfer information FTL. Indeed it does transfer...
I have read this entire thread and I'm leaning towards unusualname. The DCQE which is a variant of the QE shows a much deeper interpretation of time that I won't get into.
Just sticking with the standard QE though it is not evident from the sources I have read that the coicidence counter is...
