Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If classical cryptographic systems (RSA, ECC, AES) are used, then current security standards are met, but they become vulnerable to quantum computer attacks
Solution Approach 1:
The patent converts the harmful effect of quantum decoherence and noise into a beneficial security feature. By using decoherence-indexed key selection, the system leverages quantum noise and environmental interaction to create stable, unique cryptographic keys that are inherently resistant to quantum attacks while being generated through physically constrained processes
Solution Approach 2:
The patent changes the fundamental parameter basis of cryptography from mathematical computational hardness to physical quantum constraints. Instead of relying on mathematical problems (factoring, discrete logs), the system uses physical properties of quantum systems (decoherence dynamics, entropy, state stability) to generate and protect cryptographic keys, making them resistant to both classical and quantum attacks
2Reliability
If post-quantum cryptographic systems (lattice-based) are used, then quantum attack resistance is improved, but they remain susceptible to algorithmic breakthroughs
Solution Approach 1:
The patent replaces algorithmic/mathematical cryptographic systems with a physics-based quantum system. Instead of using mathematical structures (lattices, codes) that could have algorithmic vulnerabilities, the system uses physical quantum processes (decoherence, entropy generation, state measurement) that are governed by fundamental physical laws, making them resistant to algorithmic breakthroughs
3Reliability
If quantum key distribution (QKD) is used, then quantum security is achieved, but quantum noise and decoherence become obstacles
Solution Approach 1:
The patent fundamentally reinterprets quantum noise and decoherence from harmful obstacles to essential security features. Rather than trying to correct or avoid decoherence as QKD does, the system uses decoherence-indexed key selection to generate unique, stable cryptographic keys from quantum state evolution, making the previously harmful effects the foundation of security
Solution Approach 2:
The patent inverts the conventional approach to quantum decoherence. Instead of viewing decoherence as something to be minimized or corrected (as in QKD), the system embraces decoherence as the mechanism for generating secure keys. The inversion transforms the problem of quantum instability into a solution for cryptographic security through entropy filtering and stability metric evaluation

Data Source
AI summary
According to an embodiment, a method includes receiving and providing quantum information as input to a quantum logic gate to produce superpositioned information having a plurality of modal states associated with a modal space. Starting with the superpositioned information, a plurality of modal paths associated with the modal space is produced by recursively filtering, for a predefined number of iterations, the superpositioned information based on a coherence behavior to produce intermediate filtered information that is used as input for a next iteration from the predefined number of iterations. Decoherence dynamics is modelled across the predefined number of iterations of the recursive filtering to determine a stability metric for each modal path from the plurality of modal paths. A modal path is selected from the plurality of modal paths based on the stability metric for that modal path, the modal path representing an encryption key.
