1Productivity
If classical methods are used to determine paths between exchange locations, then the problem is solvable with simple algorithms, but the solution quality deteriorates to suboptimal paths with increased energy consumption and travel time
Solution Approach 1:
The patent replaces classical computational algorithms with a quantum computing system that uses quantum bits (qubits) and quantum operations to solve the path optimization problem. The quantum computer processes the graph representation of exchange locations and determines optimal paths through quantum mechanical operations, achieving superior optimization quality compared to classical methods.
2Area of stationary object
If the number of exchange locations increases, then the coverage area expands, but the computational complexity increases making the problem unsolvable in reasonable time
Solution Approach 1:
The patent employs a quantum computing system to handle the computational complexity arising from increased numbers of exchange locations. The quantum computer's ability to process multiple states simultaneously through superposition allows it to solve optimization problems for large-scale networks in reasonable time, whereas classical algorithms become intractable.
3Ease of operation
If simplified mappings or arbitrary human choices are used to select paths, then the decision-making process remains simple and fast, but the path optimality deteriorates in terms of energy consumption
Solution Approach 1:
The patent replaces simple heuristic or arbitrary path selection methods with a quantum computing-based optimization system. The quantum computer analyzes the graph structure and computes optimal paths that minimize energy consumption, providing scientifically determined solutions rather than simplified approximations.
