Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If qubits are allocated statically during compilation, then the compilation process is simple, but resource utilization efficiency deteriorates due to idle qubits and suboptimal execution times
Solution Approach 1:
The patent applies dynamics by transitioning from static qubit allocation to dynamic qubit allocation. The system dynamically allocates qubits during execution based on real-time availability and circuit requirements, allowing the allocation strategy to adapt to changing resource conditions rather than being fixed during compilation.
Solution Approach 2:
The patent applies preliminary action by performing qubit allocation decisions in advance during the compilation process, but with the flexibility to adjust later. The compiler prepares allocation strategies beforehand while maintaining the ability to modify allocations during execution based on actual resource availability and circuit progress.
2Loss of time
If qubits are allocated without considering real-time availability, then the allocation process is fast, but execution time increases due to suboptimal resource utilization
Solution Approach 1:
The patent applies feedback by implementing a system that monitors qubit availability and allocation status in real-time during execution. The feedback mechanism allows the system to adjust qubit allocations based on actual availability, preventing wasted execution time and optimizing resource utilization through continuous monitoring and adaptation.
3Adaptability or versatility
If more qubits are allocated to handle peak demands, then the system can execute complex circuits, but idle qubits increase resource consumption
Solution Approach 1:
The patent applies segmentation by dividing the qubit allocation into different phases and levels. Instead of allocating all required qubits simultaneously, the system segments the allocation process to allocate qubits as needed during different execution phases, reducing the total number of qubits actively utilized at any given time while maintaining the capability to handle complex circuits.
