Quantum uncertainty relations of Tsallis relative α entropy coherence based on MUBs
文献摘要：
In this paper,we discuss quantum uncertainty relations of Tsallis relative α entropy coherence for a single qubit system based on three mutually unbiased bases.For α ∈[1/2,1) ∪ (1,2],the upper and lower bounds of sums of coherence are obtained.However,the above results cannot be verified directly for any α ∈ (0,1/2).Hence,we only consider the special case of α =1/n+1,where n is a positive integer,and we obtain the upper and lower bounds.By comparing the upper and lower bounds,we find that the upper bound is equal to the lower bound for the special α =1/2,and the differences between the upper and the lower bounds will increase as α increases.Furthermore,we discuss the tendency of the sum of coherence,and find that it has the same tendency with respect to the different θ or φ,which is opposite to the uncertainty relations based on the Rényi entropy and Tsallis entropy.
