Engineering Contradiction Analysis
1Adaptability or versatility
If the number of qubits is increased to enhance computational capability, then the quantum computer can solve more complex problems, but the complexity of circuit optimization increases exponentially making manual matrix transformations unmanageable
Solution Approach 1:
The patent replaces manual mechanical matrix transformations with an automated computer-based optimization system. The computer executes algorithmic passes to analyze and transform quantum circuits, substituting the manual mechanical process with an automated computational one that can handle exponential complexity scales.
Solution Approach 2:
The optimization process is divided into discrete passes (analysis passes and transformation passes) that process the quantum circuit in manageable segments. Each pass performs specific operations on the circuit, breaking down the complex optimization into sequential, manageable steps that can be executed systematically by the computer.
2Productivity
If existing quantum circuit optimization methods are used, then some optimization is achieved, but the methods lack efficiency and cannot scale to handle larger numbers of qubits
Solution Approach 1:
The patent changes the parameters of the optimization process by introducing multiple passes with different analysis and transformation criteria. The system can adjust parameters such as the number of passes, the types of transformations applied, and the depth of analysis to optimize for different qubit counts and circuit complexities, enabling efficient scaling.
Solution Approach 2:
The optimization system incorporates feedback mechanisms where analysis passes evaluate the circuit against design criteria and transformation passes modify the circuit based on this analysis. The system iterates through multiple passes, using feedback from each analysis phase to guide subsequent transformations, improving overall efficiency and scalability.
