| 摘要： | Current limitations in quantum computing technology do not allow for very large applications of quantum algorithms, and it is the nature of quantum algorithms not only to be able to solve problems of interest much more quickly than classical means but also to do so with less resources which makes them so promising. One such problem of interest is the application of the Quantum Linear Systems Algorithm, along with a few other subroutines, to the calculation of an electromagnetic scattering cross-section via finite element methods. This work composes a resource analysis of the algorithm as well as required subroutines. Additionally, this work details the primary contributors to the resources involved as well as methods to decrease these resource requirements. The particular problem of interest to this work is the EM scattering of an aerodynamic cone within a square computational finite element region of 50 × 50 to 400 × 400 grid points. The mesh sizes resulted in a range of resource requirement from 453 to 477 logical qubits. However, varying the desired bit precision independently between 8-bit to 128-bit created resource requirements from 133 to 853 logical qubits. The desired precision of the calculations created a much larger effect on the resource requirement of the application of the algorithm. |
