Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If quantum computing operations are performed based on user intuition and experience, then the system can operate with flexible user input, but the accuracy and reliability of quantum computing operations deteriorates
Solution Approach 1:
The patent introduces an automated algorithm transformation unit as an intermediary between user input algorithms and quantum circuit execution. This intermediary systematically converts user algorithms into gate-based transformation algorithms through standardized procedures, eliminating the need for user intuition while maintaining operational flexibility. The intermediary layer ensures consistent, accurate transformation without human error.
Solution Approach 2:
The patent replaces the mechanical process of manual algorithm design and circuit construction with an automated computational system. The algorithm transformation unit uses systematic computational rules to convert user algorithms into executable quantum circuits, substituting human intuition with automated mechanical processes that ensure higher accuracy and reliability.
2Device complexity
If quantum algorithms are implemented targeting a small number of quantum dot qubits, then the system complexity is reduced, but the productivity and computational capability deteriorates
Solution Approach 1:
The patent segments the quantum computing system into distinct functional units: input processing unit, algorithm decomposition unit, quantum circuit mapping unit, driving signal generation unit, and computing execution unit. Each unit handles specific tasks independently, allowing the system to manage complex algorithms through modular processing rather than requiring simple qubit configurations.
Solution Approach 2:
The patent transitions from a one-dimensional approach (direct qubit manipulation) to a multi-dimensional processing architecture. The systematic transformation process adds multiple processing dimensions (algorithm decomposition, circuit mapping, signal generation) that enable handling of larger and more complex quantum circuits without increasing physical system complexity.
3Manufacturing precision
If systematic transformation processes are implemented for algorithm conversion, then the manufacturing precision and operational accuracy improve, but the device complexity and processing time increase
Solution Approach 1:
The algorithm transformation unit serves multiple functions within a single integrated component: it processes user input algorithms, decomposes them into gate-based transformations, generates equivalent circuits, and prepares driving signals. This multi-functionality achieves high operational accuracy without proportionally increasing device complexity, as one unit performs multiple necessary transformations.
Solution Approach 2:
The patent performs preliminary algorithm transformation and circuit generation before actual quantum computing operations. The algorithm decomposition unit and quantum circuit mapping unit prepare all necessary transformations in advance, so that when execution occurs, the system only needs to execute pre-computed circuits. This preliminary action separates the complex transformation phase from the execution phase, managing overall system complexity.
