Interestingly, these two new claims (apparently choreographed to appear the same day) came out a day before the fatal signalling loophole was identified in the raw data of the most recent "loophole free" test from August 2015. The new claims haven't provided the raw data yet, hence it would be...

You brought it up and repeated their claim. But if you have n-photon state, then a 2-photon absorptions at location 1, implies there will be zero photon absorption at some other location 2 (by pigeonhole principle) i.e. the combinations of detections eliminated include double hit on one and no...

The "locality" loophole they emphasize as remaining is a red herring. You don't expect that switching randomly polarization angles will change anything much? It never did in other photon experiments. That's relevant only for experiment where the subsystems interact, which is not true for the...

No to the strawman which has no relation to what I said. We're talking genuine non-classicality, not about word play defining label 'non-classical' for phenomena which can be simulated via local computation (i.e. local realist models), such as QO 'non-classicality' which can entirely be...

If there is absolute LHV prohibition by the empirically established facts, there is mystery in double slit. Otherwise the empirical facts of double slit experiment standing on their own are perfectly compatible with local model. The usual pedagogical presentation a la Feynman is misleading with...

That's mixing up apples and oranges. For people seeking to come up with next physics at Planck scale, such as t'Hooft or Wolfram, it is quite relevant whether cellular automata or Planckian networks or some other distributed, local computational model could at least in principle replicate the...

Just because some quasiprobability distribution turns negative, hence inapplicable as probablistic model of the phenomenon, doesn't imply all conceivable models are inapplicable. The claim to have a phenomenon which excludes all classical models even in principle is an extremely strong claim and...

It is a purely formal sign, depending on what you call "classicality". If you define it as classical fields without ZPF, then the clasical ED under such constraints cannot reproduce those effects. But if you drop such gratuitous constraints, then there is nothing non-classical about these...

The quasi-probabilities are function of space-time and have very limited regions of negativity in space-time (limited essentially by what can escape undetected within Heisenberg uncertainty). Smearing them with Gaussian distribution, such as in Husimi variant of quasi-probabilities, turns them...

The negative probabilities in photon experiments have been modeled in Stochastic Electrodynamics since 1970s. They are "non-classical" only in a narrow technical/tautological sense of "classical" meaning with zero fields as initial and boundary conditions. If you include ZPF (zero point field...

I am saying that the alleged "magic" of discrete detection points is not surprising in the least (a resonance phenomenon with non-linear response). You are missing the point of where the surprise is supposed to be (check the paper linked earlier, the intro section where they explain why the...

There is nothing that would surprise a 19th century physicist about such picture. Imagine an aftermath of a strong wind in a forrest -- there would be few scattered trees knocked down even though the wind came in continuous waves over the entire forrest. Similarly, if you watch crystallization...

That was single channel experiment (from CH inequalities) i.e. they discard half the photons on each side to begin with, before the additional explicit losses (25%) are compounded on the remaining channel on each side. It's a "little bit" misleading to claim you can fix the detection problem of...

Oh, I drop by here every few days. But I am way too busy with my day job to join discussions.

The "classicality" here means that the joint probabilities of photon counts at spacelike points factorizes (just as it would do if for the classical EM field). The largest class of "classical" states in that sense consists of all superpositions of coherent states with positive, non-singular...
