Reduction of entropy uncertainty for qutrit system under non-Markov noisy environment

doi:10.1088/1674-1056/ab7ea5

Abstract We explore the entropy uncertainty for qutrit system under non-Markov noisy environment and discuss the effects of the quantum memory system and the spontaneously generated interference (SGI) on the entropy uncertainty in detail. The results show that, the entropy uncertainty can be reduced by using the methods of quantum memory system and adjusting of SGI. Particularly, the entropy uncertainty can be decreased obviously when both the quantum memory system and the SGI are simultaneously applied.

Keywords: entropy uncertainty relation non-Markov noisy qutrit and spontaneously generated interference
