Quantum topological order is microscopically described by a long-range entanglement in the ground state wave functions. In this regard, it is expected that different topological quantum states are classified by different patterns of the long-range entanglement. In this talk, I introduce a systematic way for characterizing patterns of the long-range entanglement in different topological quantum codes. In particular, I present a universal pattern of the long-range entanglement for toric codes defined on different lattices. Furthermore, I show that the above pattern is different with the pattern of the long-range entanglement in the color code which is in another topological class.
