Secure data transfer is the main important task in the data transfer between the two or multiple nodes in the network. There are very large number of protocols and security mechanisms available. These security mechanisms can be broken by using the very high computing power processors. Quantum cryptography can be the promising secure communication using quantum physical laws. Quantum communication itself makes the communication more promising and reliable in terms of security. Many quantum cryptography protocols are proposed till date for secure communication including a popular “three-stage quantum cryptography protocol” (Kak in Phys Lett 293–296, 2006 [1]). In the current quantum cryptography protocols, the unit of data is a binary bit. Here, the proposed communication system is capable of transferring the data in the form of character rather than the bit-by-bit data transfer. This methodology uses the simple logic, i.e., the high level language is used for the data transfer. The main problem of secure key exchange is solved. The angle of rotation of the photon beam is being shared securely. Here, a secure multistage quantum communication protocol is implemented. This proposed protocol has minimized the network traffic drastically. The number of signals required for the transfer of the character is decreased six times of the previous one.
