Proposal of Encoder and Decoder for Quantum Channel Compression

Georgi Bebrov, Plamen Stoyanov, Rozalina Dimova

Recently, the quantum channel compression has been proposed. It is an encoding method, which reduces the channel resources (bits and qubits) used in a quantum secure communication protocol. The paper proposes a first-time practical implementation of this encoding process - encoder and decoder are designed. Thus, the practical feasibility of the quantum channel compression is demonstrated. The functional designs of the encoder and decoder are presented and verified by the software Quartus II v. 8.1, Web Edition. It was found that the implementation of quantum channel compression allows reducing not only the resources but also the duration of a quantum secure communication owing to a parallelism in the decoding part of the system.

Efficient Quantum Text Transfer Using Teleportation and Entropy-based Compression

Basma Abdullah Al Kharusi, Hafiz M. Asif

Abstract In classical computing systems, the physical transfer of data (i.e., bits) is essential to transfer information from one place to another through a suitable channel (wired/wireless, etc.). Unlike classical systems, Quantum communication can take place between distant users without the physical transfer of the data, i.e., quantum bits or qubits. This paper presents how a classical compression protocol, when integrated with a quantum teleportation technique, can be utilized to transfer data between spatially distant users. The quantum text teleportation protocol (QTTP) aims to enable efficient and secure transfer of text-based data over quantum channels. Simulation programs have been carried out to gauge the performance of the proposed system under different conditions and noise levels. The simulation results indicate successful teleportation between distant users. Furthermore, the performance is enhanced when QTTP was used with Huffman coding. It has been demonstrated that the protocol is reliable especially in terms of reducing the error rate under 10% bit-flip noise from 10% to 1.11%.
