Engineering Contradiction Analysis
1Productivity
If quantum states are transmitted over classical channels using conventional methods, then communication is enabled, but computational and communication overhead become resource-intensive
Solution Approach 1:
The patent creates a compressed copy of the quantum state representation using classical parameters (theta, phi values) that capture the essential features of the quantum state. This copy can be transmitted over classical channels without requiring transmission of the full quantum state, thereby reducing communication overhead while maintaining the ability to reconstruct the state at the receiving end.
Solution Approach 2:
The patent transforms the quantum state representation from a complex quantum mechanical description into a simplified parameterized form using classical variables (theta and phi angles). This parameter transformation enables efficient classical processing and communication while preserving the quantum state's essential information, directly addressing the resource consumption issue.
2Measurement precision
If quantum states are processed using conventional measurement methods, then state information is obtained, but measurement and storage requirements become resource-intensive
Solution Approach 1:
The patent extracts only the essential parameters (theta and phi values) from the quantum state representation that are sufficient for reconstruction and communication. By taking out only these key parameters rather than measuring and storing the complete quantum state, the system achieves precise state characterization with significantly reduced measurement and storage resources.
Solution Approach 2:
Instead of performing complete quantum state tomography which requires extensive measurements, the patent applies partial action by measuring only the necessary parameters to characterize the state. This partial measurement approach provides sufficient information for the intended application while avoiding the resource-intensive complete measurement process.
3Reliability
If full quantum state information is transmitted classically, then complete state reconstruction is achieved, but communication overhead increases
Solution Approach 1:
The patent creates a compact classical copy of the quantum state using parameter representations (theta, phi) that capture the essential state information. This compressed copy can be transmitted efficiently over classical channels with minimal energy consumption while still enabling accurate state reconstruction at the receiving end, thus resolving the contradiction between reliability and energy loss.
