hi zapperz. actually I do have a very intense desire to do a bell-type experiment, and have read some of the excellent recent papers that are coming out of two almost-undergraduate physics laboratories. I've investigated some of the costs involved. have you done a bell experiment? I do hope...

alas the rowe experiment is quite an admirable and highly sophisticated experimental tour de force but from the pt of view of bell testing rigor, quite lackadaisical and flawed. if you read the paper carefully and ignore the [somewhat misleading] diagram, you will realize that they used a single...

hi all, I return to post after about a year. one of the acknowledged loopholes in the bell experiments is how the coincidence circuitry behaves under what might be called "simultaneous H/V measurements" where H/V represent horizontal/vertical polarized photons at one arm. basically, if you...

fyi, one fairly straightfwd LHV theory apparently not covered by the bell impossibility/"no-go" thm: let the hidden variable determine whether the particle is detected or not, in conjunction with local polarizer angle. from what I can tell (working from memory) it is true that bell thms...

fyi, just to correct myself. I was just rereading baggott. he said something about GRW reproducing classical predictions which I misinterpreted. later he says that GRW does not give a local theory for eg the bell experiments. I must say however that there is a lot of literature on what is...

vanesch.. a question for you .. I think you have referred to the "many worlds" interpretation of qm at different points. are you familiar at all with the "Ghirardi-Rimini-Weber" model? at first I thought it was only a philosophical interpretation, but I realized slightly to my shock...

oops, one other tidbit I forgot to mention. something remarkable I ran across recently. e. eric reiter claims on his site to be doing a classic grangier,roger,aspect beamsplitter experiment with gamma rays, using a slab of aluminum as a beamsplitter (or other variations). the possible...

hi all in another recent thread there was an epic battle between a local realist & a qm formalist. good theatre. but a stalemate in the end. I would like to post just a few key recent refs I was reminded of by that thread, which might be useful for anyone interested in the area. from your...

another thought. I am not sure who 1st came up with the idea of using photons for the EPRB experiment. maybe bell or bohm? the original experiment imagined "particles" eg an atom. very,very few non-photon tests of bell's experiment have been done. its a very tricky test. there is a recent...

hey guys. I suggest everyone calculate the following. its a very sensitive calculation, not very easy to pull off, but I did something very similar via empirical/computational experiments/simulations many years ago. the details are in a paper. suppose that whenever a 1-photon goes thru a...

ok guys I think I can see a way to reconcile this or at least restate it in a way acceptable to both parties. lets attempt to state this schism in terms of a "kuhnian paradigm shift". let me postulate a new version of QM in a thought experiment. call it "QM v 2". now vanesch, suppose I...

a question. vanesch just described a simple conceptual experiment of a 1-photon state going thru a beamsplitter. as I understand it, an experimental realization of this would be a laser that emits a very brief pulse, "one photon width" so to speak. semiclassical theory (ala nite) will...

hi all, I got zapped by esteemed moderator TM on a post criticizing vanesch's style here, so let me backpeddle and just say the following. I am disappointed in this dialogue which is breaking down to a deathmatch between vanesch vs nite. from "observation" vanesch & nite are clearly...

hi all .. I have heard of 3 semiclassicalist proponents, one of them the established scientist Jaynes, criticize the classic Grangier,Roger,Aspect (GRA) photon anticorrelation experiment on the grounds that it used a polarizing beamsplitter. actually, to be more specific, (rumor is, at a...

ok look vanesch I am going to wave a white flag momentarily, but challenge you to be a little more proactive than a reactive kneejerking anklebiter. how about you come up with an experiment, please describe it for me. you say in your last post it is possible. (Im sure I am aware of some...
