Engineering Contradiction Analysis
1Reliability
If pseudo-random algorithms and deterministic approaches are used, then random numbers can be generated at a high rate using simple devices, but the generated numbers are predictable and insecure
Solution Approach 1:
The patent replaces deterministic electronic random number generation with quantum mechanical processes. Specifically, it uses quantum tunneling of charges across an insulator layer to generate inherently random numbers, substituting classical electronic mechanisms with quantum phenomena that provide true randomness and security.
2Reliability
If quantum tunnelling effect is used, then true random numbers can be generated that are resistant to prediction, but the device complexity increases
Solution Approach 1:
The patent changes the fundamental parameter of randomness generation from deterministic electronic processes to quantum mechanical tunneling processes. By adjusting the biasing voltage across the quantum tunneling barrier and controlling the tunneling conditions, the system generates true random numbers while managing device complexity through parameter optimization.
3Reliability
If quantum tunnelling charges are used to generate random signal, then true random numbers can be produced, but the signal requires filtering and amplification
Solution Approach 1:
The patent introduces intermediary components (filtering and amplification stages) between the quantum tunneling source and the final random number output. These intermediaries process the raw quantum signal to extract and amplify the random components while suppressing noise and deterministic artifacts, thereby improving signal quality.
4Productivity
If high rate random number generation is achieved through quantum tunnelling, then productivity increases, but the device requires precise gauging and control
Solution Approach 1:
The patent implements feedback mechanisms to precisely gauge and control the quantum tunneling process. By monitoring the tunneling current and adjusting the biasing voltage accordingly, the system maintains optimal operating conditions for high-rate random number generation while managing the complexity of precise control.

AI summary
A random signal can be obtained from a random tunnelling of charges from one conductor to another conductor across a quantum tunnelling barrier. The random signal can be amplified and associated to a random number. The association can be performed repetitively to generate a sequence of random numbers.
