Study of using Quantum Computer to Solve Poisson Equation in Gate Insulators
In this paper, the application of quantum computing (QC) in solving gate insulator Poisson equation is studied, through QC simulator and hardware in IBM. Various gate insulator stacks with and without fixed charges are studied. It is found that by increasing the number of clock bits and by choosing appropriate evolution time, accurate solutions can be obtained in QC simulation. However, when the real quantum hardware is used, the accuracy is substantially reduced. Therefore, a more robust quantum circuit or error correction should be employed and developed.
