SUMMARY:Quantum states are relative to observers!
DESCRIPTION:Many "pseudo-paradoxes" arise in quantum physics because
 "quantum states"  are generally considered to be absolute\, that is\,
 independent of observers. But entangled pairs of qubits in Bell states with
 two distant observers\, one per qubit\, force us to reconsider the status
 of quantum states\, revealing their observer-dependence. It is at the core
 of the "relational" interpretation of quantum mechanics\, as proposed by
 Carlo Rovelli [Rovelli 1996]\, or Asher Peres' interpretation of the
 Einstein-Podolsky-Rosen dilemma [Peres 2004\, §2]\,\nand it is related to
 the observer-dependence of time in special relativity. It is important to
 have in mind this observer-dependence in distributed quantum systems\, such
 as quantum networks where the speed of light cannot be considered as
 "infinite". It helps in understanding and accepting the physical phenomena
 involved in such systems.\n\nReferences:\n\n 	("easy" to read\, mostly
