Thermal properties of trapped ions: A Green’s-function method
Zhao Hong-min, Wei Li, Jia-tih Lin · Physical Review A · 2002
We analyzed the influence of the thermal motion from the environment on the internal states of trapped ions and the center-of-mass mode phonon using a Green's-function method. The deviation of the internal states and the variational rules of the phonon number with different trap parameters changing with the temperature are given. The upper limit of the temperature at which the gate operation can be performed safely is convenient to be found out according to different error correction capability.
