Construction of Controlled-NOT Gate with Thermal Ions
Changyong Chen, Kelin Gao · Chinese Physics Letters · 2005
A scheme is proposed to construct the controlled-NOT gate in an ion-trap computer, based on the interaction of trapped-thermal ions with bi-chromatic laser fields. In this scheme, a specific laser pulse sequence for the implementation of this gate is given. Furthermore, it is pointed out that this laser pulse sequence is different from that of Ref. [3] [Phys. Rev. Lett. 82 (1999) 1971), which cannot result in a real controlled-NOT gate.
