Quantum Internet for Healthcare: Securing Patient Data with QKD and Entanglement-Based Communication

Abstract

This research delves into the implementation of Quantum Internet in healthcare and how it could be used for securing patient data through Quantum Key Distribution (QKD) and entanglement-based communication. As cyberattacks threaten to override conventional
encryption algorithms, quantum cryptography provides highly secured protection for healthcare data. Implementing QKD and entanglement-based communication, the paper illustrates their effectiveness in delivering impenetrable encryption and data exchange security for healthcare. The performance assessment of different techniques demonstrates that the hybrid quantum-classical scheme exhibits minimum encryption latency (0.90 ms), shortest key exchange duration (0.60 s), and maximum data throughput (60.10 Mbps) with good securitystrength (512 bits). With some issues like high costs for deployment and scalability, future- proofed solutions by way of hybrid quantum-classical systems are pinpointed. The research indicates that quantum-secure medical systems have the potential to vastly improve patient confidentiality, data integrity, and medical network cybersecurity in the future.
