The measure of PBR's reality.

We review the Pusey-Barret-Rudolph (PBR) theoremcite{PBR} and their setup, and arrive to the conclusion that the reality of a quantum state $psi$ is intrinsically attached to the measurement the system described by $psi$ has undergone. We show that a state that has not been measured can be regarded as pure information, while a state that has been measured has to be regarded as a physical property of a certain system, having a counterpart in reality. This demonstration implies that the statement of PBRu0027s theorem changes in a meaningful way.
