Track Control of the States Evolution of Quantum System Based on Bloch Sphere
Lou Yuesheng, Shuang Cong · 2006
The effect of control fields is analyzed based on Bloch sphere representation of a single qubit, the conditions which parameters obey are given under two different requirements in order to achieve the transition from a arbitrary initial state to a target state, and numerical simulation is also be done to get the track of evolution on Bloch sphere. The relationship between the parameters and the track is analyzed.
