There are many obstacles in quantum circuits implementation with large scales, so distributed quantum systems are appropriate solution for these quantum circuits. Therefore, reducing the number of quantum teleportation leads to improve the cost of implementing a quantum circuit. The minimum number of teleportations can be considered as a measure of the efficiency of distributed quantum systems. Due to the complexity of reducing teleportation costs in multi-partition quantum computing, a two-level optimization is proposed. In the first level, using graph partition methods, the quantum circuit is divided into k partitions. Secondly, using a series of proposed rules and functions, the number of teleportations for the partitioned quantum circuit is improved. In previous work, only optimization at the first level has been conisdered for the distributed quantum circuits. The implementation results show that the cost of teleportation in the proposed algorithm has been improved compared to previous work on benchmark circuits.

Quantum teleportation protocol is one of the most important quantum information protocols. In this protocol, with the help of quantum entanglement and the classical channel, the state of a quantum particle is transmitted without traveling the physical distance from the sender to the receiver. Quantum teleportation, is the building block of quantum cryptographic protocols, quantum computing, and quantum networks. Therefore, since the initial ideas of the quantum teleportation protocol were proposed in 1993, many efforts have been made in the theoretical discussions and implementation of this protocol. In the present study, after introducing and classifying the theoretical ideas of quantum communication protocol, we will examine the practical implementations of this protocol. Next, the required technology requirements are presented along with the strengths and weaknesses of each.
