| Abstract(in English) | Stusy concerning quantum computer has been extensively done recently. Quantum computer theory is usually described by a state vector, so that only a pure state is considered. However, quantum computer theory is desired to be described using mixture state, because a mixture state is commonly used in quantum mechanics. Quantum computation mainly consists of two processes, that is, calculation process and observation process. The calculation process is expressed as a unitally operator followed by quantum turing machine, and the observation process is a quantum observation process to get the calculation result. In this paper, we apply the channel theory of quantum information to formulate the above calculation and observation processes and discuss Shor algorithm in our framework. |
