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.

A perimeter gated single-photon avalanche diode operates a probabilistic bit device through modulation of the gate voltage to tune the dark count rate. The presence or absence of an avalanche event during a sampling interval are equivalent to a first and second logical state, similar to traditional computing bits. By modulating the gate voltage, the probability distribution of the logical states becomes sigmoidal. Multiple probabilistic bit devices can be interconnected through a weighted network to create a system useful for probabilistic computing.
