@@ -24,3 +24,8 @@ dynamics are elucidated. Using this the graphical representation is introduced
 and some operations on the graphical states are explained. Following is
 a chapter describing the implementation of these techniques and some performance
 analysis.

+Being able to simulate large stabilizer states is particularly interesting for 
+exploring quantum error correction strategies as fault tolerant quantum computing
+requires several layers of encoding - so called concatenated codes \cite{nielsen_chuang_2010} -
+that require many physical qbits to encode one logical qbit.
