sufficient to destroy which way information.

Let |i refer to the state where the photon travels on path i. Then
one can write down a few relations, such as:
|1 = 1/sqrt{2}|3 + 1/sqrt{2}|4 = |5
|2 = 1/sqrt{2}|3 - 1/sqrt{2}|4 = |6
If a photon is detected on path 5, then the probability it travelled
along path i is 5|i.
