The paper: Next-Generation Secure Communication: Investigating Quantum Key Distribution Techniques for Ultrasonic Network Infrastructure

Abstract

The increasing demand for secure communication has driven the need for state-of-the-art solutions that guarantees confidentiality, integrity,  and authenticity. This research investigates the feasibility of quantum key distribution (QKD) for ultrasonic network infrastructure, enabling next-generation secure communication.  QKD, based on quantum mechanics principles,  provides unrestricted security for data transmission.  Our study explores the integration of QKD with ultrasonic communication systems. Results shows that Shannon's entropy reaches a maximum of 1 bit for probability of a bit being 1 or 0 is balanced (p =0.5). The quantum bit error rate (QBER) shows that as the number of errors increases, the QBER grows linearly from 0 to approximately 0.1. The signal to noise (SNR) is evaluated by considering signal and noise power values, where the SNR varies with noise levels indicating resilience to interference. The key rate reveals drop from 10,000 to 9,500 keys as QBER increases from 0 to 0.1. Additionally,  the research also investigates ultrasonic wave propagation, where the wave velocity increases from approximately 30m/s to 100m/s as the bulk modulus increases from 10^9 to 10^11 Pa. The quantum mutual information shows that the mutual information increases as the entropy of Alice's and Bob's data increases,  with values ranging from 0.5 to 1 bit. The study also evaluated errors reconciliation efficiency,  where corrected entropybvalues of 120 to 256 result in VueScan ranging from 0.47 to 1. Conclusively, the eavesdropping detection probability of detection increases from 0.01 to nearly 1 as the single detection probability increases from. 0.001 to 0.1. The findings highlight the intricate relationships between quantum communication metrics and the need for careful consideration of these factors in system design. This research paper proposes strategies for improving the reliability,  efficiency,  security and quality of quantum communication systems.
