Have a look at this, which is somewhat related:

<It is proposed and argued below that 1) measurement is unitary 
evolution when
properly considered as a three-way interaction, and thus 2) there is no 
barrier due to
measurement to reversibility or backward influence, and further 3) there 
is no
fundamental randomness generated by measurement.

Ultimately, it will be beneficial to give up the deeply held assumption of
unidirectional) cause-and-effect, and rely on the more general notions 
of dependence
and influence. If relinquishing cause and effect is too unsettling or 
painful, we can at
least think in terms of bi-directional cause. We will take both views 
interchangeably.
Several interpretations of quantum mechanics have a truly bi-directional 
structure,
most notably the Transactional Interpretation (TI) of Cramer [1]. The TI 
does not rule
out retrocausal signaling, and in fact asserts that influence is “a 
two-way street”, where
the future to some degree determines the past as well as vice-versa. 
However, the TI
does include some fundamental randomness in that there may be a 
stochastic choice
made among several potential absorbers for a given emitter transaction.>
