量子物理與元件

The classical semiconductor physics and circuits concepts are no longer completely adequate for understanding electric properties in nanoscale transistors nowadays and quantum physics must be considered for device design. This course focuses on nanoelectronics and quantum electronics in low-dimensional semiconductor devices as well as the underlying quantum transport physics. Processing quantum characters has been thought to be the key to advance the current semiconductor transistors for information processing. Thanks to the breakthrough in semiconductor fabrication techniques, the devices based on the principles of quantum mechanics has been already realizable. This course will also illustrate the quantum physics for semiconductor-based quantum computation using electron spins. Finally, we will introduce the physical implementation of quantum computation for practical applications. 隨著半導體製程技術的精進,近幾十年來人們所追尋的摩爾定律之終結將可被預期,因此對於不同元件架構抑或是不同計算思考邏輯的相關研究更是如火如荼的進行中。而隨著半導體元件尺度的微縮,奈米電子乃至於量子電子學的概念愈顯其之重要性。本課程將著重於探討低微度半導體元件之設計與其中電荷與自旋傳輸之量子物理機制並對其進行控制,以期能將其運用於量子資訊的處理與計算。 **量子資訊數學與理論面向分析建議可修讀電信所主開的"量子訊息與計算(Quantum Information and Computation)": https://timetable.nycu.edu.tw/?r=main/crsoutline&Acy=112&Sem=1&CrsNo=535357&lang=zh-tw
