It is thought that the techniques operating entangled states are some of the principal ones in quantum information processing. Therefore, procedures constructing other types of entangled states from some entangled states are useful. In this paper, we first show methods that dynamically change the number of entangled qubits during communication. Next, we propose a sharing protocol called the anonymous entangled state sharing protocol. By using this protocol, a party's message can be split among unknown parties because the parties can share entangled states without knowing each other. Finally, we show protocols that can recover an original message and split it to other parties without revealing its shared messages.
