Engineering Contradiction Analysis
1Measurement precision
If traditional electronic equipment is used to detect qubits in low temperature environments, then detection accuracy can be maintained, but detection cost and time consumption increase significantly
Solution Approach 1:
The patent replaces traditional electronic detection equipment with an imaging device combined with machine learning algorithms. The imaging device captures images of qubits, and machine learning models analyze these images to predict qubit properties and detect defects, eliminating the need for complex low-temperature electronic detection systems while significantly reducing detection time and cost.
Solution Approach 2:
The patent creates a digital copy of the qubit through imaging, capturing visual information that represents the qubit's state. This digital copy is then analyzed by machine learning models to infer qubit properties, replacing the need for direct physical measurement in low-temperature environments with a computational approach based on image data.
2Ease of manufacture
If traditional detection methods are used, then detection can be performed with existing equipment, but the process becomes labor-intensive and costly
Solution Approach 1:
The patent implements an automated detection system where the imaging device automatically captures qubit images and the machine learning model automatically analyzes these images to predict qubit properties and identify defects. This self-service approach eliminates manual intervention and reduces labor intensity, significantly improving detection efficiency and productivity.
Solution Approach 2:
The machine learning model provides feedback about qubit properties and potential defects based on the imaging data, enabling real-time assessment and adjustment of the qubit preparation process. This feedback mechanism improves detection efficiency by allowing continuous monitoring and optimization without requiring manual inspection.
3Reliability
If detection is performed after qubit preparation, then existing detection methods can be applied, but defects occurring during preparation cannot be detected
Solution Approach 1:
The patent enables preliminary detection of qubit defects during the preparation process by capturing images at intermediate stages and using machine learning models to predict properties in real-time. This allows defects to be identified before final preparation is complete, enabling corrective actions to be taken and improving overall reliability while maintaining high productivity.
4Measurement precision
If low temperature environment is used for qubit detection, then detection accuracy is maintained, but detection cost becomes very high
Solution Approach 1:
The patent replaces expensive low-temperature electronic detection equipment with a more cost-effective system using imaging devices and machine learning algorithms. The imaging device can operate in standard temperature conditions, and the machine learning model processes images to predict qubit properties, significantly reducing the cost of detection while maintaining accuracy.
Solution Approach 2:
The patent creates digital images as copies of qubit states that can be analyzed by machine learning models at standard temperatures, eliminating the need for expensive cryogenic detection equipment. This copying approach allows accurate property prediction without the high costs associated with maintaining low-temperature environments.
