In order to transmit images and audio securely, the authors present the Quantum Image Teleportation Protocol (QITP) and Quantum Audio Teleportation Protocol (QATP), which utilizes the Quantum Teleportation (QT) technique combined with Huffman Coding. The QITP secures the teleportation of quantum states of an image while simultaneously encrypting and decrypting them using Huffman Coding since it is only possible to recover or decode data if the prefix codes are known. To test their approach, the authors transformed pixels or RGB values from digital images into text, which was then fed into the Huffman Coding Technique. It has the advantage of compressing the entire text, which makes it faster to transmit vast amounts of information. This work also demonstrates the Quantum Audio Teleportation Protocol (QATP) with and without Huffman coding. For proof of concept, experimental evaluations were performed for both suggested QITPs and QATPs (Standard QITP, QITP with Huffman Coding, Standard QATP, QATP with Huffman Coding), using IBM Quantum Assembly Language (IBM QASM) Simulator and real quantum hardware using the Quantum Information Science Kit (Qiskit), a quantum computing platform.

Quantum teleportation should be able to teleport states or parts of states in arbitrarily large Hilbert spaces, which will require concatenation of quantum teleportation processes that operate for a fixed dimension. We introduce the concept of concatenated quantum teleportation and obtain exact expression for teleportation fidelities for two simple cases. We also derive the conditions when concatenated teleportation can be considered as quantum.

Abstract In this paper, a detailed analysis of basic quantum teleportation under standard basis measurement is presented, and a novel method for quantum teleportation is proposed. This method utilizes a physical channel, eliminating the need for direct information transmission. Additionally, a new quantum teleportation protocol is introduced by integrating this approach with existing teleportation techniques. The proposed protocol not only improves the security of quantum teleportation but also mitigates the effects of noise and decoherence.
