The rapid development and extensive application of the Internet of Things (IoT) have brought new challenges and opportunities to the field of communication. By integrating quantum secure communication with the IoT, we can provide a higher level of security and privacy protection to counteract security threats in the IoT. In this paper, a hybrid quantum communication scheme using six-qubit entangled states as a channel is proposed for specific IoT application scenarios. This scheme achieves hierarchical control of communication protocols on a single quantum channel. In the proposed scheme, device A transmits data to device B through quantum teleportation, while device B issues control commands to device A through remote quantum state preparation technology. These two tasks are controlled by control nodes C and D, respectively. The transmission of information from device A to device B is a relatively less important task, which can be solely controlled by control node C. On the other hand, issuing control commands from device B to device A is a more crucial task requiring joint control from control nodes C and D. This paper describes the proposed scheme and conducts simulation experiments using IBM's Qiskit Aer quantum computing simulator. The results demonstrate that the fidelity of the quantum teleportation protocol (QTP) and the remote state preparation protocol (RSP) reach an impressive value of 0.999, fully validating the scheme's feasibility. Furthermore, the factors affecting the fidelity of the hybrid communication protocol in an IoT environment with specific quantum noise are analyzed. By combining the security of quantum communication with the application scenarios of the IoT, this paper presents a new possibility for IoT communication.

With the continuous development of the Internet of Things (IoT) technology, the industry's awareness of the security of the IoT is also increasing, and the adoption of quantum communication technology can significantly improve the communication security of various devices in the IoT. This paper proposes a scheme of controlled remote quantum state preparation and quantum teleportation based on multiple communication parties, and a nine-qubit entanglement channel is used to achieve secure communication of multiple devices in the IoT. The channel preparation, measurement operation, and unitary operation of the scheme were successfully simulated on the IBM Quantum platform, and the entanglement degree and reliability of the channel were verified through 8192 shots. The scheme's application in the IoT was analyzed, and the steps and examples of the scheme in the secure communication of multiple devices in the IoT are discussed. By simulating two different attack modes, the effect of the attack on the communication scheme in the IoT was deduced, and the scheme's high security and anti-interference ability was analyzed. Compared with other schemes from the two aspects of principle and transmission efficiency, it is highlighted that the advantages of the proposed scheme are that it overcomes the single fixed one-way or two-way transmission protocol form of quantum teleportation in the past and can realize quantum communication with multiple devices, ensuring both security and transmission efficiency.
Abstract This paper puts forward a novel hierarchical controlled asymmetric bidirectional hybrid quantum communication scheme that can be applied to hierarchical quantum information transmission tasks in various application scenarios. In this scheme, with only Charlie’s assistance, Alice can accomplish the less crucial task of remotely preparing any single-qubit state for Bob. Simultaneously, Bob aims to transmit any two-qubit states to Alice via quantum teleportation. As a more vital communication task, apart from obtaining the consent of the control agent Charlie, Bob also requires the help of another control agent, David. Only with the combined control and support of Charlie and David can this task be successfully completed by Bob. In an ideal environment, the success rate of this protocol is 1. Given that noise is inevitable in practical communication, this paper further investigates the impact of different noises on this communication scheme and analyzes and compares its efficiency with other existing similar schemes. The proposed protocol outperforms existing hierarchical quantum communication solutions in terms of task generality and flexibility. By assigning different levels of controllers to different tasks, it provides users with greater flexibility to meet their specific needs, especially in scenarios requiring both multi-level authorization control and hybrid quantum communication.
Abstract This paper presents a hierarchical controlled asymmetric bidirectional hybrid quantum communication protocol applicable to hierarchical quantum information transmission tasks across diverse scenarios. The scheme incorporates two communication tasks: (1) With the assistance of controller Charlie, Alice can perform the lower-priority task of transmit arbitrary single-qubit state to Bob via quantum teleportation; (2) As a higher-priority task, Bob needs to remotely preparing arbitrary two-qubit states for Alice. This process requires not only authorization from controller Charlie but also collaborative support from another controller David. Theoretical analysis demonstrates that the protocol achieves a 100% success rate under ideal conditions. To address noise interference in practical communication, the impacts of different noise models on protocol performance are systematically investigated, followed by an efficiency comparison with existing similar schemes. Results indicate that this protocol significantly outperforms current hierarchical quantum communication solutions in terms of task generality and flexibility. By assigning differentiated control levels to different tasks, the protocol provides users with enhanced configurability to meet specific requirements, particularly in complex scenarios requiring integrated multi-level authorization control and hybrid quantum communication.
Abstract This paper proposes a hierarchical controlled bidirectional hybrid quantum information transmission (HCBHQIT) protocol for arbitrary two-qubit states based on a special ten-qubit entangled state. The protocol implements a hierarchical control mechanism where high-level agent Alice can complete quantum teleportation of any unknown two-qubit state to Bob with only one controller Charlie’s assistance, while low-level agent Bob requires collaborative control from both Charlie and an additional controller David to remotely prepare arbitrary known two-qubit states at Alice’s location (with Alice remaining completely unaware of the state). We comprehensively analyze protocol implementation in noisy environments, particularly examining fidelity degradation under various noise conditions, and calculate the intrinsic efficiency through comparative evaluations. The scheme innovatively integrates multi-level control architecture with bidirectional hybrid communication technology over a shared quantum channel, with detailed discussions for both ideal and noisy scenarios. Demonstrated to maintain practical value across multiple application scenarios, this protocol advances controllable quantum communication systems through its hierarchical access management and dual-directional information transfer capabilities.
