Dynamics of a driven spin coupled to an antiferromagnetic spin bath
Xiao-Zhong Yuan, Hsi-Sheng Goan, Ka-Di Zhu
We study the behavior of the Rabi oscillations of a driven central spin (qubit) coupled to an antiferromagnetic spin bath (environment). It is found that the decoherence behavior o…

Geometric phase of a central spin coupled to an antiferromagnetic environment
Xiao-Zhong Yuan, Hsi-Sheng Goan, Ka-Di Zhu
Using the spin-wave approximation, we study the geometric phase (GP) of a central spin (signal qubit) coupled to an antiferromagnetic (AF) environment under the application of an e…
