1Productivity
If quantum computing is used to solve support vector machine tasks, then processing speed and accuracy are improved, but device complexity increases
Solution Approach 1:
The patent introduces a quantum processor as an intermediary component between classical data input and classification output. The quantum processor contains a quantum kernel machine that receives training data, performs quantum mechanical computations to determine class memberships, and outputs classification results. This intermediary quantum system enables exponential speedup for specific machine learning tasks while maintaining compatibility with classical computing frameworks.
Solution Approach 2:
The patent segments the support vector machine task into distinct functional components: a classical data input layer, a quantum kernel machine layer for computation, and an output layer for classification results. The quantum processor is further segmented into quantum memory for storing training data and a quantum kernel machine for performing computations. This segmentation allows each component to be optimized independently and facilitates integration with existing classical systems.
2Measurement precision
If quantum kernels are used for classification, then measurement precision is improved, but difficulty of detecting and measuring increases
Solution Approach 1:
The patent implements a feedback mechanism where the quantum kernel machine processes training data through quantum mechanical operations, and the results are measured and fed back to determine class memberships. The quantum system performs repeated measurements and computations, using the outcomes to refine classification decisions. This feedback loop enables high measurement precision by leveraging quantum parallelism and interference effects while managing the complexity of quantum measurement through iterative optimization.
