Korotkov and Jordan think that 'undoing' a 'weak
measurement' (a sort of 'soft' and 'looong' quantum 
measurement invented by Aharonov, Albert,
and Vaidman) may be interpreted as erasing, by a
second 'weak measurement', the information obtained 
from a first 'weak measurement'.

They also wrote a paper about that ...

We could also 'undo' a 'weak' quantum suicide then,
and we could also 'undo' a 'weak' MWI branching,
if things went wrong :-)
