Solution Overview

Problem

Conventional random number generators, including true random number generators based on quantum mechanics, lack the ability to self-correct or adapt during operation, leading to potential biases and deviations from expected statistical distributions, which are only detected after number generation.

Innovation Solution

A self-correcting or adaptive random number generator system that monitors its own characteristics and uses quantum statistical tests to adjust operating parameters, incorporating feedback mechanisms to ensure the generation of random numbers that meet performance criteria, such as a quantum random number generator with a quantum preparation unit, analysis unit, and control mechanisms for continuous adaptation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional quantum random number generators are used, then random numbers can be generated based on quantum uncertainty, but the system cannot detect or correct biases in real-time, leading to potential deviations from expected statistical distributions

Engineering Contradiction:
Improverandomness qualityVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a feedback mechanism where test results from randomness evaluation are fed back to control the quantum random number generation process. The system continuously monitors statistical quantities and adjusts generation parameters to maintain randomness quality, resolving the contradiction between reliability and complexity by making the system adaptive rather than static.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs self-diagnosis and self-correction by automatically testing its own output and adjusting its operation. The quantum random number generator monitors its own statistical properties and corrects deviations without external intervention, improving reliability while keeping the overall system architecture manageable through autonomous operation.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If independent testing of random number sequences is performed after generation, then randomness can be evaluated, but the failure of one sequence does not affect subsequent sequences and the randomness cannot be known beforehand

Engineering Contradiction:
Improverandomness evaluation accuracyVSAvoidtesting delay
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary testing and evaluation during the generation process itself rather than after completion. By continuously monitoring statistical quantities as numbers are generated, the system can detect randomness deviations in real-time and adjust before significant deviations occur, eliminating the time loss associated with post-generation testing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The randomness evaluation and generation processes run continuously and simultaneously rather than sequentially. The system maintains continuous monitoring of statistical properties throughout the generation process, ensuring that randomness quality is maintained without interruption or delay, and allowing immediate correction if deviations are detected.

Inventive Principle:
Principle #20Continuity of useful action

3Reliability

If the quantum system is prepared with perfect superposition and measurement is perfectly aligned, then maximum entropy or randomness is achieved, but in practice there are deviations such as nonpure quantum preparation or misaligned measurement

Engineering Contradiction:
Improveentropy maximizationVSAvoidimplementation difficulty
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The system transitions from a static configuration to a dynamic, adaptive system that can adjust its parameters in real-time. By making the quantum preparation and measurement alignment adjustable based on feedback from randomness testing, the system can compensate for manufacturing imperfections and maintain high entropy despite practical limitations in preparation purity and measurement alignment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters based on feedback from statistical testing. When deviations from expected randomness are detected, the system adjusts generation parameters to correct the underlying causes, whether they stem from imperfect quantum preparation or measurement misalignment, thereby maintaining reliability despite implementation difficulties.

Inventive Principle:
Principle #35Parameter changes

AI summary

A system and method for generating random numbers. The system may include a random number generator (RNG), such as a quantum random number generator (QRNG) configured to self-correct or adapt in order to substantially achieve randomness from the output of the RNG. By adapting, the RNG may generate a random number that may be considered random regardless of whether the random number itself is tested as such. As an example, the RNG may include components to monitor one or more characteristics of the RNG during operation, and may use the monitored characteristics as a basis for adapting, or self-correcting, to provide a random number according to one or more performance criteria.
