The maximum intra-cavity compression of squeezed light derived from the analytical solution is 1/16 （vacuum fluctuations 1/4）. To compare it with the previous 1/8 of degenerate optical parametric amplification （DOPA）, it seems that squeezing for NOPA is superior to DOPA.展开更多

So a chart of conversion, in which elements are named differently, is proposed. Next, experiment about Bell’s inequalities violation is described in another way, and we hope a clearer one. Main result is Bell’s inequalities would not be violated! The explanation would come from confusion between the definition of the correlation function S1, and a property S2. And consequently, Einstein, Podolski and Rosen would be right on the local “hidden” variable.展开更多

No ＂spooky＂ action at a distance is required. The ＂metabrain＂ produces a plethora of correlated streams of consciousness which are the totality of observable reality. The mental world and the observable physical world are the same. As in a dream, there are no independently existing observable objects; for an object to exist it must be observed. In this paradigm there is mutual interaction between the streams of consciousness and the ＂metabrain.＂ The non-observable ＂metabrain＂ is the source of the non-local hidden variables which produce our observations. The currents of this ＂metabrain＂ are the quantum probability amplitudes and the firing of the ＂synapses＂ result in our conscious observations. The Born probability rule for quantum calculations is derived within this paradigm and helps to resolve the EPR paradox.展开更多
