Yes thats better sorry I struggle with english :-)
Which poses all kinds of questions like: Is reality an absolute? Or is it something which each individual creates for itself?
QM answers that definitely via a law called Bell's Inequality (http://en.wikipedia.org/wiki/Bell's_theorem)
The violations of Bell's inequalities, due to quantum entanglement, just provide the definite demonstration of something that was already strongly suspected, that quantum physics cannot be represented by any version of the classical picture of physics.
Many who believe in a one real physical world interpretation like Einstein were horrified by this and science has spent nearly 100 years trying to fight it.
We usually call our two observers Alice and Bob (A & B I know novel) and QM will proove they never experience the same reality it's not possible for them to unless there are hidden variables behind the scenes which we can show don't exist again via classic test that is EPR (
http://en.wikipedia.org/wiki/EPR_paradox). This may be simpler to understand (

Einstein struggled to the end of his life for a theory that could better comply with causality, protesting against the view that there exists no objective physical reality other than that which is revealed through measurement interpreted in terms of quantum mechanical formalism.
Einstein really disliked QM :-)
I must admit when I first moved from GR to QM studies it was hard but it grows on you. It's not that it's really mind blowing just different to how you experience the world.
Do human beings (conscious and otherwise), animal beings, insects, vegetables, whatever all experience the same reality?
For the same reasons above no two humans would experience the same "physics reality".
I would say animals etc even more so because there sensory inputs are so different for example they can hear much higher up the audio spectrum.
Reality seems to be about the observer much more than the world is one of the main things QM teaches us.
