| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系碩博士班 === 101 === Quantum computer has been the most popular topic in these few years. By making a two-level system, such as a “Josephson junction”, we can realize a quantum bit called “qubit”. In this present, we will use complex mechanics, which is a quantum theory used particle path instead of probability density to describe a quantum system. Under the framework of complex mechanics, we can not only provide the dynamic of the electron to show how the tunneling is in progress, but also do the simulation of tunneling with all the parameters of material before design work. This will be very useful and necessary for the manufacturing process in the future. In the last part of this present, we add an extra voltage to the system to make an affect in the electron’s Hamiltonian. By adjusting this parameter, we can control the dynamics of the electrons to make the tunneling happened. This will be a new and intuitive method in quantum control theory, and in the future, we even can use the classic control theory to analysis the stability of electron’s dynamics with the present of trajectories.
