Engineering Contradiction Analysis
1Productivity
If machine learning models are used to generate quantum channel codes, then communication rates approach theoretical capacities, but the complexity of encoding and decoding operations increases
Solution Approach 1:
The patent applies parameter changes by using machine learning models to learn optimal encoding and decoding parameters for quantum channels. The model iteratively updates parameters to maximize communication rate while managing complexity through learned transformations rather than fixed complex operations.
Solution Approach 2:
The patent substitutes traditional mechanical or algorithmic encoding/decoding mechanisms with a machine learning-based system. The neural network learns to perform encoding and decoding operations, replacing conventional quantum error correction codes with data-driven approaches that achieve capacity while adapting to channel characteristics.
2Measurement precision
If quantum autoencoders are used for channel coding, then capacity-achieving codes are learned effectively, but the training and implementation time increases
Solution Approach 1:
The patent applies preliminary action by pre-training the quantum autoencoder model offline to learn optimal encoding and decoding strategies. Once trained, the model can be deployed for rapid encoding and decoding operations, separating the time-consuming learning phase from the operational phase.
Solution Approach 2:
The patent maintains continuity of useful action by using the trained autoencoder model for continuous encoding and decoding operations. The model once trained provides sustained capacity-achieving performance without requiring repeated training, enabling continuous high-rate communication.
