Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex gates are unrolled to basis gates and mapping is performed to quantum processor topology, then the quantum circuit can be executed on the quantum processor, but the circuit complexity and execution time increase
Solution Approach 1:
The patent performs gate unrolling and topology mapping in advance during the compilation phase, so that when the quantum circuit is executed on the quantum processor, the complex gates have already been decomposed into basis gates and mapped to the correct topology. This preliminary preparation resolves the contradiction by doing the time-consuming work before execution, making the actual quantum execution faster and more reliable.
2Difficulty of detecting and measuring
If qubit relaxation threshold visualization is generated by altering visual appearance of qubits, then debugging and optimization of quantum circuits is improved, but the system complexity increases
Solution Approach 1:
The patent uses color changes and visual appearance alterations of qubits to represent different relaxation thresholds. By visually encoding qubit states and relaxation levels through color gradients or intensity changes in the circuit diagram, the system makes it easy to detect and measure qubit relaxation without requiring complex additional measurement apparatus. The visualization component renders qubits with different visual properties based on their relaxation thresholds, enabling intuitive debugging and optimization.
3Measurement precision
If the quantum processor computes new thresholds by multiplying qubit relaxation values, then accurate error analysis is achieved, but the computational overhead increases
Solution Approach 1:
The quantum processor itself performs the computation of new thresholds by multiplying qubit relaxation values, utilizing its own computational capabilities. This self-service approach allows the system to achieve precise error analysis using the quantum processor's native operations, minimizing the need for additional classical computational resources and reducing overall computational overhead.
