Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional circuit architecture is used to increase integration density, then processing power per unit area improves, but heat generation and wiring difficulty increase
Solution Approach 1:
The patent replaces conventional charge-based transistor switching with spin-based electron transport and manipulation. By utilizing electron spin states (up/down) instead of charge presence/absence, the system achieves logic operations with significantly reduced heat generation, as spin transport is a cooler mechanism compared to charge-based operations in traditional CMOS circuits.
Solution Approach 2:
The invention changes the fundamental operating parameter from charge (electrical voltage) to spin (magnetic moment orientation). This parameter change enables logic operations to be performed through spin-dependent transport mechanisms, which generate less heat and allow for higher integration densities without the thermal management constraints of conventional architectures.
2Productivity
If conventional circuit architecture is used to increase integration density, then processing power per unit area improves, but wiring difficulty increases
Solution Approach 1:
The patent creates a universal spin-based platform where the same spin-transport mechanisms can perform multiple functions: logic operations, memory storage, and signal transmission. This multi-functionality reduces the need for separate specialized components and complex interconnect structures, thereby simplifying wiring and manufacturing compared to heterogeneous conventional architectures.
3Object-generated harmful factors
If quantum network circuits are used, then heat generation is reduced and integration scalability improves, but device complexity increases
Solution Approach 1:
The patent segments the quantum computing functionality into modular spin-based units that can be independently fabricated and then assembled. Each unit contains localized spin-transport elements that perform specific logic or memory functions, and these modules can be tiled to create larger systems, thereby managing complexity through standardization and modularity.

Function Achieved in This Case
Enables efficient construction of logic circuits and massive parallel computation by leveraging the Aharonov-Bohm effect, overcoming traditional integration limits and achieving faster performance through quantum network configurations.
Implementation Method 1
QNT is based upon the Aharonov-Bohm effect, a quantum mechanical phenomenon in which an electrically charged particle is affected by an electromagnetic field (E, B), despite being confined to a region in which both the magnetic field B and electric field E are zero for a longitudinal direction of propagation of the electron.
