1Quantity of substance
If the number of quantum bits is increased to achieve large-scale quantum computing, then computing power is improved, but control complexity increases and becomes difficult to manage
Solution Approach 1:
The control system is divided into multiple layers: a high-level quantum algorithm layer that users interact with, and lower-level control circuit layers that handle hardware-specific details. This segmentation allows users to work with quantum bits at an abstract level without being burdened by the complexity of controlling each individual quantum bit through hardware circuits.
Solution Approach 2:
A control system intermediary (controller) is introduced between the quantum algorithm and the quantum bit control circuits. This intermediary automatically generates appropriate control signals based on the quantum algorithm requirements, masking the complex hardware control details from users and enabling intuitive control of large-scale quantum systems.
2Measurement precision
If direct coupling of quantum bits to control device is used for verification, then control precision is maintained, but ease of operation deteriorates due to complex hardware knowledge requirements
Solution Approach 1:
The controller acts as an intermediary that receives high-level quantum algorithm instructions and automatically translates them into precise low-level control signals for the quantum bit circuits. This allows users to operate quantum computers intuitively without needing to understand complex hardware control details, while the system maintains precise control through automated signal generation.
Solution Approach 2:
The control system performs self-service by automatically generating and optimizing control signals based on the quantum algorithm requirements. The system autonomously handles the complex task of translating abstract quantum operations into precise hardware control signals, eliminating the need for users to manually configure hardware parameters while maintaining control precision.
3Measurement precision
If multiple layers of knowledge (quantum devices, control circuits, quantum algorithms) are required, then control accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The control architecture is segmented into distinct layers: quantum algorithm layer, controller layer, and quantum circuit layer. Each layer handles specific tasks independently, allowing users to work at the high-level algorithm layer without needing knowledge of lower-level control circuit details, while the system maintains accurate control through the coordinated operation of all layers.
Solution Approach 2:
The controller serves as an intermediary layer that bridges the quantum algorithm and quantum circuit layers. It automatically translates high-level quantum operations into precise low-level control signals, enabling users to achieve accurate quantum control without requiring knowledge of multiple technical layers. The intermediary handles the complexity internally while presenting a simple interface to users.
