It was clear "always". For me todays reply is : It's imposible to generate pair of photons with known polarizations... Second learn is ( very good and simply explained by all of you ) : 0 and 90 = -45 and +45 i saw it difference before, now after calculation understand how it works...

It's what i needed , now all is clear and i know where was my important knowledge gaps.... Thank You !!! One question more if can.... about this: yes, I wrote that I misunderstood it earlier. But the question is if in this particular case the 2 entangled photons are polarization entangled...

Yes, I am well aware of this theorem. I directly agree, which is why I thought such entanglement was impossible. Still, many people try to use entanglement indirectly. Me too :).

Tkanks, for reply. here : https://en.wikipedia.org/wiki/Spontaneous_parametric_down-conversion i found it : This suggests to me that it is possible. But !!! According to my computer simulations, such a device can be easily used to send information at superluminal speed, which is ruled out...

Hello everyone! I don't know where to look for information - maybe here it will work :) Is there a generator of entangled photons with fixed polarization? If not, is it theoretically possible to build or is it against the laws of physics. I need this knowledge for further computer...
