    A The experiment of Kim et al. (1999) (with small modification)

    There is no need for any calculations. Yet, If you do not feel confident in your own understanding of quantum theory, you do not have to provide your predictions. :)

    A The experiment of Kim et al. (1999) (with small modification)

    Because, no one could, so far. (who was strong supporter of quantum theory). If you can provide your predictions, please do so. And my conviction is that that those modifications will alter experiment results in a specific maner.

    A Is Entanglement Swapping Driven by Post-Selection or Bell State Measurement?

    A Is Entanglement Swapping Driven by Post-Selection or Bell State Measurement?

    From 245 pairs that met requirements (coincidence window) 80% showed entanglement. (Original experimental version). So, is your predictions is saying that: higher number out of those pairs will show entanglement (example 90% out of 245) in Alt-BSM experimental version?

    A The experiment of Kim et al. (1999) (with small modification)

    Modification specifications: Variation 1. Placement of horizontal polarizer after BSa. Placement of vertical polarizer after BSb. Variation 2. Placement of horizontal polarizer after Ma. Placement of vertical polarizer after Mb. Question1: Is it safe to assume, that this modification...

    A Is Entanglement Swapping Driven by Post-Selection or Bell State Measurement?

    Or, we have low resolution model for light "photon" that works great at long distances, yet fails at short ones. Point "assumption" about photon (massless particle), is a useful simplification for low resolution model, that removes all complexity about nature of energy delivery. Yet, that...

    I Few Questions about: TU delft "A loophole-free Bell test"

    doubt: a feeling of uncertainty or lack of conviction. feeling: an emotional state or reaction. reason:(synonyms) rationality, logic, reasoning. Doubt is an emotional reaction, not rational by definition, needs no conscious reason. Doubt may be justified or not. Justified: having, done...

    I Few Questions about: TU delft "A loophole-free Bell test"

    I do appreciate your patience, and have not intention to abuse it. There is a reason for detection at location A and B aswell as at location C. Is the reason is to determine are measured fotons entangled or not? 245 runs were selected because detection at A and B met the criteria...

    I Few Questions about: TU delft "A loophole-free Bell test"

    Hey Steve. It kind of was personal speculation, based on incomplete understanding. Yet, isn't everything is, that threads on edge of knowledge (understanding)? It is a funny place, where we are all silly. Cheer up, and if you see me here stumbling and tripping, don't let it annoy you, let it...

    I Few Questions about: TU delft "A loophole-free Bell test"

    I want to thank for all replies. They helped me understand what bit of information I was missing, excluded some possibilities and narrow down my focus. There is one more thing that I am interested about, yet I could not find it. There was 245 runs that met requirements. Out of those 245 runs...

    I Few Questions about: TU delft "A loophole-free Bell test"

    I agree. "there is no "quantum memory" from run to run." Simplifying: For successful runs there are 2 pairs of entangled fotons. And 4 detectors. 2 at location C, 1 at location A and 1 at location B. Detectors at location C show opposite spins correlation and detectors at location A and B...

    I Few Questions about: TU delft "A loophole-free Bell test"

    So, of course, experiment would produce the same results, yet predictions for "hidden variable" could be different, if some current assumptions would turn out to be false, therefore interpretation of results could change aswell. There is assumption for quantum theory as well as for "hidden...

    I Few Questions about: TU delft "A loophole-free Bell test"

    My fault, to be more precise. Are they entangled before (before entanglement swapping)? Is there assumption that spin of emitted fotons cannot change when reflecting or passing through beam spliter? Or under any other conditions? (In context of hidden variable analysis and statistical...

    I Few Questions about: TU delft "A loophole-free Bell test"

    Electrons in diamonds are not entangled. Is above statement correct? Spin of emitted fotons if detected separately would not show any correlation? Is above statement correct? Is there assumption that spin of emitted fotons cannot change when reflecting or passing through beam spliter? Or...
