Engineering Contradiction Analysis
1Productivity
If multiple quantum jobs are executed simultaneously on a quantum processor, then the processing speed and productivity are improved, but the risk of crosstalk and noise between different qubit sets increases
Solution Approach 1:
The patent segments the quantum processor into distinct qubit sets, assigning specific qubits to each quantum job. By dividing the processor resources and isolating qubit sets, the system enables simultaneous execution of multiple quantum jobs while minimizing crosstalk between them. The scheduling component divides quantum jobs into separate qubit allocations, and the isolation component identifies idle qubits that can serve as barriers between active qubit sets.
Solution Approach 2:
The patent introduces idle qubits as intermediary elements between active qubit sets. These idle qubits act as buffers or barriers that isolate active qubits from each other, preventing harmful crosstalk while still allowing simultaneous execution. The isolation component specifically identifies and assigns idle qubits to serve as separators between different quantum job qubit sets, enabling safe parallel execution.
2Productivity
If the entire quantum processor is utilized for multiple quantum jobs, then the productivity is improved, but the complexity of managing and isolating qubits increases
Solution Approach 1:
The patent implements self-service mechanisms where the scheduling component automatically determines qubit assignments and the isolation component automatically identifies idle qubits for isolation purposes. The system autonomously manages qubit allocation and isolation without requiring manual intervention, reducing the operational complexity of managing multiple quantum jobs simultaneously. The components automatically handle the bookkeeping and coordination of qubit sets.
3Object-affected harmful factors
If idle qubits are assigned to isolate active qubits, then the crosstalk is reduced, but the number of qubits required increases
Solution Approach 1:
The patent utilizes idle qubits that would otherwise be unused or discarded resources. Instead of wasting these idle qubits, the isolation component assigns them to serve as separators between active qubit sets. This approach recovers and repurposes idle qubit resources to fulfill the isolation function, avoiding the need to add extra qubits beyond what is already available in the processor. The idle qubits are reclaimed and put to useful service as isolation barriers.
