Thanks - with your help plus Wikipedia I now have an hypothesis about your
statement. It seems to boil down to "Schrodinger's Cat has nothing to do
with quantum computers other than they both depend on quantum
superpositions." Fair enough.
When I read somebody's speculation that the reality we inhabit may be a
quantum computer, it enlarged my concept of all possible realities to
include all possible states of quantum superpositions. In half of these
S.C. is alive; in half it is dead.
