Solution Overview
Problem
The challenge is to maintain the temperature of a quantum semiconductor chip and its control wiring conductors at a level close to absolute zero during quantum operations, as increased current consumption leads to temperature rises, which is insufficient for high-capacity quantum bit systems.
Innovation Solution
A quantum calculator system is designed with a dilution refrigerator setup that includes a metal body cooled by a refrigeration tube, a quantum bit array chip with silicon-spin quantum bits, and control wiring conductors arranged across the refrigeration tube to manage heat dissipation effectively, using a time division sequence to alternate the operation of even and odd-numbered arrays to minimize temperature increases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the capacity of quantum bits is increased to provide sufficient computer resources, then the quantum operation capability is improved, but the temperature rise due to increased current consumption worsens
Solution Approach 1:
The quantum bit array chip is divided into multiple regions and sub-regions, each performing quantum operations independently. The control wiring conductors are also divided into multiple groups connected to different regions. This segmentation allows distributed heat generation across multiple locations, preventing localized overheating while maintaining high quantum bit capacity.
Solution Approach 2:
The patent employs time-division operation where even and odd-numbered arrays are operated alternately. During operation of one array, the other array can be cooled or处于 standby state. This periodic action prevents continuous heat accumulation, allowing the system to maintain high quantum bit capacity without sustained temperature rise.
2Adaptability or versatility
If more control wiring conductors are added to drive high-capacity quantum bits, then the control capability is improved, but the temperature rise due to increased current consumption worsens
Solution Approach 1:
The control wiring conductors are organized into multiple groups, with each group connected to specific regions or sub-regions of the quantum bit array. This segmentation distributes the current load across multiple conductor groups rather than concentrating it in few conductors, reducing resistive heating in each individual conductor while maintaining comprehensive control capability.
3Productivity
If the quantum operation is performed at high capacity, then the computational power is improved, but the quantum fidelity deteriorates due to temperature rise
Solution Approach 1:
By alternately operating even and odd-numbered arrays, the system ensures that while one array is performing quantum operations at high capacity, the other array is in a cooling or standby phase. This periodic action prevents continuous heat accumulation that would degrade quantum fidelity, thereby maintaining high quantum fidelity even during high-capacity operations.
