Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If centralized routing algorithms are used to establish quantum communication channels, then routing control is simplified, but scalability and resource utilization deteriorate
Solution Approach 1:
The patent implements self-service by enabling quantum devices to autonomously perform routing decisions and entanglement establishment without centralized control. Each device maintains its own routing table and actively participates in selecting optimal paths, thereby improving scalability and resource utilization while retaining operational simplicity through automated local decision-making
Solution Approach 2:
The routing protocol dynamically adapts to changing network conditions by continuously updating routing tables based on current entanglement availability and link states. This dynamic approach allows the system to respond to on-demand requests and network changes in real-time, improving resource utilization without requiring complex centralized coordination
2Productivity
If multiple quantum paths are established simultaneously, then throughput and number of simultaneous quantum-user pairs increase, but resource collisions and decoherence risk increase
Solution Approach 1:
The system performs preliminary actions by pre-establishing multiple quantum paths and entanglement pairs before actual data transmission occurs. This allows the network to have ready-to-use communication channels, increasing throughput while managing decoherence risk through proactive resource allocation and path selection
Solution Approach 2:
The routing protocol incorporates feedback mechanisms where quantum devices continuously monitor link states and entanglement quality. Based on this feedback, the system dynamically adjusts path selection to avoid resource collisions and maintain optimal communication quality, thereby supporting high throughput while minimizing decoherence risk
3Loss of time
If entanglement swapping is performed quickly to reduce waiting time, then decoherence is reduced, but synchronization complexity increases
Solution Approach 1:
The patent implements periodic action through time-slotted operation where entanglement swapping and data transmission occur in synchronized periodic cycles. This periodic structure reduces waiting time by ensuring timely entanglement establishment while managing synchronization complexity through regular, predictable timing patterns that ease coordination between multiple quantum devices
