Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional quantum systems are used, then spin states can be maintained, but electrical access to spin states is not achieved
Solution Approach 1:
The patent introduces an intermediary system consisting of multiferroic nanoparticles embedded in a conductive metal-organic framework. This intermediary enables electrical control of spin states through the conductive framework while maintaining spin coherence through the multiferroic material properties, thus providing both electrical access and magnetic moment tunability simultaneously
Solution Approach 2:
The patent employs composite materials by combining multiferroic nanoparticles (providing spin state stability) with a conductive metal-organic framework (providing electrical accessibility). This composite structure allows the system to achieve both electrical access to spin states and tunable magnetic moments through the synergistic properties of the combined materials
2Productivity
If quantum systems are scaled up, then functionality increases, but coherence times decrease
Solution Approach 1:
The patent divides the quantum system into discrete, modular units (individual multiferroic nanoparticles) embedded within a conductive framework. This segmentation allows for scalable assembly of multiple qubits while maintaining the coherence properties of individual units, as each nanoparticle acts as an independent quantum element with preserved spin coherence
Solution Approach 2:
The conductive metal-organic framework serves as an intermediary that enables scalable coupling between individual quantum units while preserving their coherence. The framework provides a structured environment that maintains spin states across multiple units, allowing scalability without proportionally increasing noise and decoherence
