Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple superconducting processors are implemented in a system, then processing power and scalability are improved, but system complexity and difficulty of control increase
Solution Approach 1:
The system is divided into multiple independent superconducting processor chips, each capable of autonomous operation. This segmentation allows parallel processing while maintaining individual processor simplicity, resolving the contradiction between system productivity and device complexity
Solution Approach 2:
A communication network with packet routers serves as an intermediary between multiple processors, enabling coordinated operation without direct complex interconnections. This mediator layer simplifies control while maintaining high processing power through parallel operations
2Reliability
If qubit coherence time is extended, then computational accuracy is improved, but system operational duration requirements increase
Solution Approach 1:
Computation is divided into segments distributed across multiple processors, each operating within shorter coherence time windows. This allows the system to achieve high computational accuracy through parallel processing while individual qubits don't need to maintain coherence for extended durations
Solution Approach 2:
The system maintains continuous computational progress through parallel processing across multiple processors. Even as individual qubit coherence periods expire, other qubits continue computing, ensuring continuous useful action without requiring any single qubit to maintain coherence indefinitely
