Unlike brute-force search or probabilistic quantum measurement, the method achieves decryption in a single engineered collapse. Hardware embodiments include optical photonic systems, neuromorphic processors, and resonant field architectures. Applications extend to RSA, Diffie-Hellman, elliptic curve cryptography, lattice-based post-quantum protocols, blockchain, and secure messaging frameworks. Proof-of-concept demonstrations on small instances, including factorization of $N=15$, illustrate feasibility at toy scale. Scaling to larger cryptosystems is envisioned through adaptive parameter control, resonance calibration, and experimental implementation.
