Not without a serious dose of science fiction and a weakening or
redefinition of the term "same experience".

If by same experience we want same time, location, hardware and 
software state, B would have to be "turned into" A, but B could not be 
both A and B, so if B is turned back from A to B, I cannot see 
how it could be done. It almost feels more like a logic problem
than a philosophy problem. ;)
