CONTROLLING GEOMETRIC PHASE IN DISSIPATIVE SYSTEM BY DIRECT FEEDBACK
H. Y. SUN, Chengcheng Zhou, Ke Xue · International Journal of Quantum Information · 2012
We calculate the geometric phase associated to a dissipative system which is influenced by system's state (feedback). The dependence of the geometric phase on the control feedback parameters is calculated and discussed. This direct feedback procedure can overcome spontaneous emission effect and generate a fluctuation on the geometric phase.
