This paper empirically validates the theoretical frameworks presented in "A Quantum Technology Adoption Framework" [2] and "Why QRNG Confuses PQC" [3]. We conducted a series of file encryption and decryption experiments using NIST-standardized Post-Quantum Cryptography (PQC) algorithms on a defined dataset of PDF and large-scale video files. The performance metrics, including speed and throughput for various KEM and digital signature algorithms (ML-KEM, ML-DSA, Falcon, SPHINC
