Hi everybody ...
One of the one-qbit simple quantum gate is X which defined by:
X: |0> ----- |1>
|1> ----- |0>
but how does this gate ( unitary operator ) act on |i> state? (i=0 or 1)
I mean at first we have to measure what state is ( 0 or 1) and so flip them but after we know the state, it will calapse to |0> or |1>.
so X|i>=|-i> is not correct according what I said.
