Resumen de: US20260280876A1
0000 A recognition-state quantum informational encryption (RSQIE) system and method provide quantum-resistant secure digital communication and data protection. Digital information is encoded into recognition-coherence scalars using a recognition mapping in which a recognition scalar R is computed as R=x/(x+X_opt), where x is a positive parameter associated with a symbol and X_opt is a predetermined constant. One or more quantum states are prepared based on the recognition scalars and encrypted using an encryption transformation derived from a recognition-coupled interaction that depends on message-associated and key-associated recognition operators. A corresponding inverse transformation decrypts the encrypted representation to recover the digital information. In some embodiments, verification includes computing a coherence deviation deltaR=abs(R_expected−R_measured) and triggering a responsive action when deltaR, or a windowed statistic derived from deltaR, exceeds a threshold, thereby providing breach indication in disturbance-sensitive implementations.
