Solution Overview
Problem
Current methods for generating random numbers, whether physical or computational, suffer from systematic bias and non-uniform distributions, making them unsuitable for cryptographic applications where true randomness is essential to prevent prediction of future numbers.
Innovation Solution
A system utilizing quantum mechanical principles, specifically diffraction of particles through slits, where particles are emitted towards a screen with slits, creating a diffraction pattern on a detector with regions that trigger unique output signals, processed to generate true random numbers without bias, using a processor to associate these signals with unique number-values and generate sequences of random numbers.

Engineering Contradiction Analysis
1Reliability
If physical methods are used to generate random numbers by measuring physical sources of entropy, then random numbers can be generated, but systematic bias in the measurement process or entropy source results in non-uniform distribution
Solution Approach 1:
The patent changes the fundamental parameter of randomness generation from classical physical measurement to quantum mechanical process. By utilizing quantum diffraction and the probabilistic nature of particle arrival at detector regions, the system transforms the generation mechanism to inherently produce uniform distribution without systematic bias, as quantum processes are fundamentally unpredictable and equiprobable across detection regions.
2Productivity
If computational methods are used to generate pseudo-random numbers based on seed input, then random number sequences can be generated, but the output is completely determined by the seed and algorithm rather than being truly random
Solution Approach 1:
The patent replaces computational algorithms with quantum mechanical processes. Instead of using deterministic algorithms that process seed inputs, the system employs quantum particle diffraction and detection, where the arrival position of individual particles at detector regions is fundamentally unpredictable. This substitution of physical quantum mechanisms for computational methods ensures true randomness while maintaining generation speed.
3Productivity
If traditional random number generators are used, then random numbers can be produced, but a malicious observer can determine a fingerprint of the generator and predict future random numbers
Solution Approach 1:
The patent fundamentally changes the physical basis of randomness from classical to quantum domain. By measuring the arrival positions of quantum particles after diffraction, the system generates random numbers based on quantum indeterminacy rather than classical physical processes. This parameter change ensures that no systematic patterns or fingerprints exist that could be exploited by observers, as quantum measurement outcomes are inherently unpredictable and free from deterministic biases.
