When a measurement occurs the wavefunction is now in the from of a constant multiplied by a single eigenfunction. The constant is known as an eigenvalue.
The eigenvalue is the information as a result of the measurement.
The initial wavefunction representing an entangled state does not contain information.

Hmm..
From what I'm reading, (about the "Aspect" experiment), it appears that physicists agree that the list of possible outcomes at each of two detectors, (of entangled pairs), are identical and are
correlated but there is no
causation evident. This being because, in no way, can one
control or predict the outcome of any particular measurement. Thus there is no message, no information whatsoever.
Very subtle interpretation here …
