  Wigner's friend thought experiment is intended to reveal the inherent tension
between unitary evolution and measurement collapse. On the basis of Wigner's
friend experiment, Brukner derives a no-go theorem for observer-independent
facts. We construct an extended Wigner's friend scenario including three
laboratories, namely, Alice's laboratory, Bob's laboratory and Charlie's
laboratory, where Alice, Bob and Charlie are standing outside the laboratories
while their friends are placed inside their own laboratories. We consider
quantum simulation via Q\# quantum programming and also realize the primary
quantum circuits using IBM quantum computers. Then, we calculate the
probabilities and corresponding statistical uncertainties. It has been shown
that the results of quantum simulation are clearly consistent with theoretical
values, while it has a slightly higher error rates for the experimental results
of quantum computers mainly because of a series of quantum gates, especially
CNOT gates.
