Engineering Contradiction Analysis
1Power
If quantum processors are scaled up from few qubits to many qubits, then computational power is increased, but device complexity increases
Solution Approach 1:
The patent divides the quantum computing system into multiple distributed quantum processors located at different geographical positions. Each processor operates semi-independently but is connected through quantum channels, allowing the system to scale computational power by adding more processors rather than building a single complex machine. This segmentation approach manages complexity by distributing it across multiple locations.
Solution Approach 2:
The patent introduces quantum channels as intermediary components that connect distributed quantum processors. These channels, established through satellite-based entanglement distribution, serve as mediators that enable coherent operation between separate quantum processors without requiring direct physical connection, thus managing system complexity while enabling scaling.
2Adaptability or versatility
If quantum processors are interconnected via quantum channels, then scalability is improved, but loss of information increases due to transmission over long distances
Solution Approach 1:
The patent uses satellite-based entanglement distribution as an intermediary mechanism to establish quantum channels between geographically separated quantum processors. The satellite acts as a mediator that distributes entangled photon pairs to ground stations, enabling quantum communication over long distances without direct point-to-point connections, thus improving scalability while managing information loss through quantum error correction protocols.
Solution Approach 2:
The patent employs quantum error correction codes that change the parameter representation of quantum information. By encoding quantum states in a way that is resilient to transmission errors, the system maintains information integrity over long distances through quantum channels, allowing scalable interconnection without proportional information loss.
3Length of stationary object
If satellite-based entanglement distribution is used to connect distant quantum nodes, then connection distance is improved, but device complexity increases
Solution Approach 1:
The patent introduces a satellite as an intermediary component that enables quantum entanglement distribution over long distances. Instead of requiring direct ground-based quantum channels that would be limited by terrestrial infrastructure complexity, the satellite acts as a mediator that can establish entangled states between distant ground stations, significantly increasing connection distance while managing device complexity through space-based architecture.
Solution Approach 2:
The patent transitions from terrestrial quantum communication to space-based quantum communication by utilizing the satellite orbit dimension. This dimensional change allows quantum nodes to be connected over much larger distances than ground-based systems can achieve, as the satellite can serve as a relay point in three-dimensional space rather than being constrained to linear ground-based paths.
