*V*-type three-level atom embedded in a zero-temperature bosonic reservoir and driven by a classical field. By transforming the problem into the model of an open driving-free

*V*-type atom, we can then solve the dynamics analytically and study the evolution of QFI numerically. It is found that the QFI of both...

*weight*parameter $$\theta $$ θ of a target state is always independent of the Hawking temperature

*T*. This implies that if we encode the information on...

*W*-class states. We present new analytical monogamy inequalities for the concurrence of assistance, which are shown to be tighter than the existing ones. Furthermore, analytical monogamy inequalities are obtained for the negativity of assistance.

*M*possible measurements, and each measurement with

*K*outcomes, the Bell inequalities based on the choice of two orbits are derived. When the observables are much enough,...

*u*-constacyclic codes over the ring $${\mathbb {F}}_p+u{\mathbb {F}}_p$$ F p + u F p are given, where

*p*is an odd prime and $$u^2=1$$ u 2 = 1 . Under a special Gray map from $${\mathbb {F}}_p+u{\mathbb {F}}_p$$ F p + u F p to $${\mathbb {F}}_p^2$$ F p 2 , some new non-binary quantum codes are obtained by this class of...
