"Participants were asked to imagine that they
could intuitively perceive a low intensity laser
beam in a distant Michelson interferometer. If
such observation were possible, it would
theoretically perturb the photons' quantum
wave-functions and change the pattern of light
produced by the interferometer."

I did not read the paper (still to be published).
But why did he use a Michelson interferometer?

A much better, and *cleaner* experiment would be
to (try to) perturb photon's quantum wave-functions
using a Mach-Zehnder interferometer [1]. Since
- in this case - the (eventual) perturbation of
one of the (two) 'amplitudes', would cause
the 'wrong' detector to register the photons,
and not the usual one [2].

An even better idea would be to use
a Franson (two-photon) interferometer [3].
Since, in this case, the behaviour of the two 'wings'
of the interferometer (they can be space-like separated)
is exactly the same (photons go to the same
detectors in both 'wings', if the set-up is
symmetrical). Now if you put the 'psychics' on
one 'wing' of the interferometer and not
on the other one .....

[2] In a Mach-Zehnder interferometer
the photons always go to one detector, and not
to the other one, because of the composition
of the (two) amplitudes at the end of their
geometrical paths.
