 A photon in the up state $\begin{pmatrix} 1 \\ 0 \end{pmatrix}$ is sent through the first beam splitter.
 Afterwards the photon is in the state $\begin{pmatrix} \frac{1}{\sqrt{2}} \\ \frac{1}{\sqrt{2}} \end{pmatrix}$ 
+So the photon is in a superposition between up and down, so between passing  through the box with maybe a bomb and passing through empty air.
+
+It makes a difference whether a bomb is inside the box or not!!
+
+First, what happens if there is no bomb:
+Photon can pass through both paths.
+Second beam splitter is reached in any case.
+
+After the second splitter the photon is in the state : $B(\begin{pmatrix} \frac{1}{\sqrt{2}} \\ \frac{1}{\sqrt{2}} \end{pmatrix})$ = $\begin{pmatrix} 1 \\ 0 \end{pmatrix}$  
+After measuring we get the following distribution:
