Efficient quantum-error correction for QoS provisioning over QKD-based satellite networks

Ping Wang, Xi Zhang, Genshe Chen

Quantum cryptography is one of the most promising technologies for guaranteeing the absolute security in communications over various advanced networks, including fiber networks and wireless networks. In particular, quantum key distribution is an efficient encryption scheme on implementing secure satellite communications between satellites and ground stations. However, it faces many new challenges such as high attenuation and low polarization-preserving capability or extreme sensitivity to the environment. In order to guarantee the quality of service (QoS) provisioning of quantum communications over 3D satellite networks, we need to focus on the security problem and throughput efficiency through correcting the errors resulted from the objective and adversary influences. To overcome these problems, we model the noisy quantum channel and implement an efficient quantum error correction scheme to ensure the security and increase the quantum throughput efficiency in QKD-based satellite networks. The simulation results obtained show that our proposed efficient QEC scheme for QoS guarantee outperforms the other existing quantum error correction schemes in terms of security and the quantum throughput efficiency.

Quantum Error Correction Technique for Quantum-Based Satellite Communication

Veenu Yadav, Deepshikha Agarwal, Krishna Kant Agarwal

QKD is performed to secure quantum communication between the ground stations and satellite. To implement the quantum channel, better security and output are required. QKDP is a successful way for satellite quantum communications for secure networks. In this paper, we discuss error correction schemes and their comparison, quantum communication procedures A, D, and M represent encoding, decoding, and performed measurement operations. A/P represents classical bit to quantum conversion. We also present the proposed model designed for a quantum channel to improve the performance of QKD protocol satellite-based communication under problem-environmental noise, adversary attacks, atmospheric turbulence.

Analysis of Quantum Key Distribution Based Satellite Communication

Vishal Sharma, Subhashish Banerjee

Quantum key distribution is an effective encryption technique which can be used to perform secure quantum communication between satellite and ground stations. Quantum cryptography enhances security in various networks such as optical fibers and wireless networks. In addition to this, these networks become vulnerable in presence of high attenuation due to atmospheric effects and noise. Hence, errors occurs due to decoherence. The noisy quantum channel is modeled and implemented by the redundancy-free quantum error correction scheme which provides better security and throughput efficiency as shown in simulation results.
