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 security
strength (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.
