FTL-gedanken experiment. I never really got feedback on my last proposal in 'Communication systems and entanglement'- so I try here with a slightly modified version: A source produces entangled photons against Alice: p beam - and against Bob: s beam. These are used to transmit from Alice to Bob. Transmitter: Setting T (0): Polarized beam splitter PBS (v) followed by two detectors. PBS (v) forcing the photons to choose between being polarized in the direction v degrees or perpendicular = direction v+90. T (0) maintaining an agreed time and should create an interference pattern at Bob's receiver. Setting T (1): Polarized beam splitter PBS (v +45), followed by two detectors. PBS (v +45) forces the photons to choose between being polarized in the direction v +45 degrees or in the direction v-45. T (1) maintains the same scheduled time and should not create an interference pattern with Bob. Receiver: Starts with a PBS (v+90). The transmitted beam encounters a device to read any interference pattern - a double slit or (if the double slit is problematic), an interferometer (for example Mach Zehnder with BS = a half silvered mirror). The reflected beam is stopped by a detector. The distance between the source and Alice's detectors are less than the distance from the source and into the beginning of the receiver so that the photons will be measured at Alice place before they reach the receivers PBS (v+90). T (0): p-photon v degrees so is the corresponding s-photon perpendicular = v+90. All of these are transmitted by PBS (v+90) and would like to form an interference pattern. p-photon v+90 s-photon v, ie. reflected by the PBS (v+90) and detected. Together, the system works here as a 'half Coincidence counter': Of the 'entangled' only the desired reach the double slit / interferometer and can form an interference pattern. Noise will not be stopped. But since this is a gedanken experiment imagined the noise to be minimal. T (1): p-photon v+45 degrees, so is the corresponding s-photon perpendicular = v-45. Half of those are transmitted by PBS (v+90) and would like to form an interference pattern. p-photon v-45 degrees then the corresponding s-photon perpendicular = v+45. Half of those are transmitted by PBS (v+90) and would like to form an interference pattern. Because of reflection should be a half-wave difference between p: v+45 and p: v-45, so the two patterns are shifted half-wave - as - for example, a fringe pattern and an anti-fringe pattern. Together equalize each other. Example: Walborn et al: Double-slit quantum eraser. With Quarter Wave Plates and polarizer set to theta =v. FIG 4 shows a fringe pattern.
