  One of the answers to the measurement problem in quantum theory is given by
the Copenhagen-Interpretation of quantum theory (i.e. orthodox quantum theory)
in which the wave function collapse happens in (by) the mind of observer. In
fact, at first, great scientists like Von Neumann, London, Bauer and Wigner
(initially) believed that the wave function collapse occurs in the brain or is
caused by the consciousness of observer. However, this issue has been stayed
yet very controversial. In fact, there are many challenging discussions about
the survival of quantum effects in microscopic structures of the human brain,
which is mainly because of quick decoherence of quantum states due to hot, wet
and noisy environment of the brain that forbids long life coherence for brain
processing. Nevertheless, there are also several arguments and evidences that
emergence of large coherent states is feasible in the brain. In this paper, our
approach is based on the latter in which macroscopic quantum states are
probable in the human brain. Here, we simulate the delayed luminescence of
photons in neurons with a Brassard-like teleportation circuit, i.e. equivalent
to the transfer of quantum states of photons through the visual pathways from
retina to the visual cortex. Indeed, our simulation considers both classical
and quantum mechanical aspects of processing in neurons. As a result and based
on our simulation, it is possible for our brain to receive the exact quantum
states of photons in the visual cortex to be collapsed by our consciousness,
which supports the Copenhagen-Interpretation of measurement problem in quantum
theory.
