摘要

本研究探討量子電腦應用於微中子自旋-風味震盪。首先，我們使用古典電腦模擬高能宇宙微中子在穿越帶有磁場之介質的風味震盪。接著，使用量子電腦模擬上述的微中子震盪問題，量子閘為微中子混合矩陣和隨時變矩陣，量子線路則為測量到的震盪機率。最終，我們比較了量子電腦和古典電腦的運算結果。

This thesis discusses the neutrino spin-flavour oscillations solved by using quantum computers. Firstly, we use the classical computer to simulate the neutrino flavour oscillations in medium or the neutrino spin-flavour oscillations when ultrahigh-energy cosmic neutrinos propagate in a local interstellar magnetic field. Secondly, quantum computers are used to simulate the above oscillations. From the quantum gates, we encode the PMNS matrix and the time evolution matrix, the quantum circuit is constructed to measure the oscillation probabilities. Finally, we make a comparison of the accuracy in the quantum computing results
and the classical computing results.
