The masking condition for quantum state in two-dimensional Hilbert space
Mei-Yi Wang, Su-Juan Zhang, Chen-Ming Bai +1
This paper focuses on quantum information masking for quantum state in two-dimensional Hilbert space. We present a system of equations as the condition of quantum information maski…

An improved bound for strong unitary uncertainty relations with refined sequence
Jing Li, Sujuan Zhang, Lu Liu +1
We derive the lower bound of uncertainty relations of two unitary operators for a class of states based on the geometric-arithmetic inequality and Cauchy-Schwarz inequality. Furthe…
