1Productivity
If conventional silicon chip computers increase transistor integration density, then computing capability is improved, but power consumption and heat dissipation problems worsen
Solution Approach 1:
The patent replaces the conventional silicon-based mechanical computing system with a quantum computing system that utilizes quantum mechanical phenomena (superposition, entanglement) to perform computations. This substitution fundamentally changes the physical basis of computation, allowing for higher computational capability without the power consumption constraints of classical silicon chips.
2Productivity
If conventional silicon chip computers increase transistor integration density, then computing capability is improved, but manufacturing difficulties worsen
Solution Approach 1:
The patent substitutes the complex mechanical transistor-based manufacturing process with quantum circuit fabrication techniques. This allows for the creation of quantum computing systems that avoid the physical limitations and manufacturing difficulties associated with continuing to increase transistor density on silicon chips.
3Device complexity
If Daubechies wavelet transform matrix dimension is reduced from high dimension to 4×4, then circuit complexity is decreased, but transformation precision may be compromised
Solution Approach 1:
The patent segments the high-dimensional Daubechies wavelet transform matrix into smaller 4×4 sub-matrices through Kronecker product decomposition. This segmentation allows the complex transformation to be implemented using multiple simpler matrix operations, reducing circuit complexity while maintaining the full transformation precision through the mathematical properties of the decomposition.
Solution Approach 2:
The patent changes the parameter representation of the wavelet transform by expressing the high-dimensional matrix in terms of smaller matrix parameters through Kronecker products. This parameter transformation allows the same mathematical operation to be performed with reduced complexity, as the 4×4 matrices can be more efficiently implemented in quantum circuits.
