Quantum Text Teleportation Protocol for Secure Text Transfer by using Quantum Teleportation and Huffman Coding

In this work, the authors present Quantum Text Teleportation Protocol (QTTP) that uses Quantum Teleportation (QT) technique and Huffman Coding for secure text transfers. The QTTP enables the teleportation of quantum states of text (for example, email) in a secure manner, while simultaneously encrypting and decrypting them using Huffman Coding since data can only be retrieved or decoded if the prefix codes are known. The Huffman Coding approach offers the benefit of compressing the entire text, resulting in faster transmission of large amounts of information. For proof of concept, the authors experimentally evaluated both of the proposed QTTPs (Standard QTTP and QTTP with Huffman Coding) using Quantum Information Science Kit (Qiskit), a quantum computing platform and simulated on IBM QASM Simulator and on IBM real quantum hardware.
