1Productivity
If quantum circuits are executed sequentially on physical qubits, then qubit coherence time is maximized, but system throughput is limited
Solution Approach 1:
The system performs preliminary actions by buffering quantum circuits in a queue and pre-processing them before execution. The scheduler component analyzes and prepares multiple quantum circuits in advance, allowing the physical qubits to be allocated and prepared ahead of time, thus reducing idle time and maximizing coherence utilization while maintaining high throughput
Solution Approach 2:
The patent implements continuous useful action by maintaining a buffering mechanism that continuously accepts and prepares quantum circuits. The scheduler continuously allocates qubits and manages the execution pipeline, ensuring that qubits are constantly being used for meaningful computation rather than idle waiting, thereby maximizing coherence time utilization while sustaining high system throughput
2Productivity
If multiple quantum circuits are executed concurrently to increase throughput, then system usage is maximized, but qubit availability is reduced due to limited coherence time
Solution Approach 1:
The system applies dynamics by implementing a flexible scheduling mechanism that dynamically allocates and reallocates qubits based on the coherence status and execution requirements of quantum circuits. The scheduler dynamically adjusts the mapping between quantum circuits and physical qubits, optimizing resource utilization while ensuring qubit availability throughout the coherence window
Solution Approach 2:
The patent introduces an intermediary buffering mechanism that acts as a mediator between the quantum circuits and physical qubits. This buffer receives quantum circuits, prepares them in advance, and hands them off to the physical qubit layer when ready, allowing for better synchronization and ensuring qubit availability without compromising the integrity or coherence of the quantum states
3Reliability
If qubit operations are performed quickly to maximize coherence time, then qubit availability increases, but computational accuracy may be compromised
Solution Approach 1:
The system performs preliminary analysis and optimization of quantum circuits before execution. The scheduler component pre-processes circuits to optimize their mapping to physical qubits, ensuring that the most coherence-efficient allocations are made in advance. This allows for faster execution while maintaining accuracy by pre-optimizing the circuit-qubit mapping strategy
