This is probably a silly suggestion, but could a physicist do the
observing directly, and then be dosed with Rohypnol or some other
drug interrupting short term memory, preventing the memory of
observation from going into long term storage? Or you could borrow
that luckless neuro patient of Oliver Sacks who forgets everything
from minute to minute, living in a timeless present. Of course you'd
need to fire the electron to a detector in Mars orbit or something to
get sufficient lag. (I assume quantum erasure requires something more
drastic than simple interruption of memory, though.)
