Engineering Contradiction Analysis
1Reliability
If separate encoding processes are used for quantum error correction and homomorphic encryption, then error correction and security capabilities are independent and well-defined, but resource demand for operations becomes high
Solution Approach 1:
The patent merges quantum error correction encoding and homomorphic encryption encoding into a single unified encoding process. The quantum error correction code is designed to simultaneously provide both error correction and encryption functionalities, eliminating the need for separate encoding steps and thereby reducing computational resource demand while maintaining both reliability and security capabilities.
Solution Approach 2:
The quantum error correction code is designed with multi-functionality, serving both as an error correction mechanism and as an encryption scheme. This universal code structure allows a single encoding operation to achieve multiple objectives: protecting against quantum errors and securing data through homomorphic encryption, thus optimizing resource utilization.
2Reliability
If separate encoding processes are used for quantum error correction and homomorphic encryption, then security and error correction are independent, but device complexity increases
Solution Approach 1:
The patent combines separate encoding processes into a single integrated encoding operation. The quantum error correction code is constructed such that it inherently incorporates encryption capabilities, allowing one encoding step to simultaneously achieve error correction and security objectives, thereby simplifying the overall device structure and reducing operational complexity.
3Reliability
If two encoding processes are used for quantum homomorphic encryption, then security and error correction are independently optimized, but the number of operations increases
Solution Approach 1:
The patent merges two separate encoding operations into a single unified encoding process. The quantum error correction code is designed to perform both error correction and homomorphic encryption simultaneously, reducing the total number of operations required while maintaining security capabilities through the integrated code structure.
