擁有高速運算優勢，量子電腦被視為「下個世代的運算工具」，比傳統電腦更加強大，世界先進科技大廠紛紛投入研發資源，各國政府也都密切關注。 其中量子位元作為量子電腦的運算核心，使用疊加與糾纏的量子力學現象，以達到兩個狀態的線性組合，可讓量子演算法快速處理資訊。 此篇論文主要研究矽自旋量子位元的電子傳輸，並分成兩部分，第一部分是單電子電晶體的模型開發，第二部分發展兩個位元的矽自旋電子的電路模型，包含一個單電子電晶體作為讀取元件，並透過模擬實際電路去對比兩者結果來驗證此模型。

With the advantages of high-speed computing, quantum computers are regarded as ”computing tools for the next generation” and are more powerful than traditional computers which is highly invested in RD resources by advanced technology companies, and governments are paying close attention as well. Qubits, as the computing core of quantum computers, use the quantum mechanical phenomenon of superposition and entanglement to achieve a linear combination of two quantum states, allowing quantum algorithms to quickly process information. This paper mainly studies the electron transport of silicon spin qubits and is divided into two parts. The first part is the model development of single-electron transistors, and the second part develops the circuit model of two-bit silicon spintronics, including a single-electron transistor which is used as the readout element, and the model is verified by simulating the actual circuit to compare the results of the practical experiment.
