Stronger sum uncertainty relations for non-Hermitian operators
Xiao-Feng Song, Yi-Fang Ren, Shuang Liu +2
The uncertainty relations (URs) of two arbitrary Hermitian and non-Hermitian incompatible operators represented by the product of variances have been confirmed theoretically and ex…

Theoretical investigation of the relations between quantum decoherence and weak-to-strong measurement transition
Xiao-Feng Song, Shuang Liu, Xi-Hao Chen +1
This paper delves into the crucial aspects of pointer-induced quantum decoherence and the transition between von Neumann's projective strong measurement and Aharonov's weak measure…
