Abstract Work and efficiency of quantum Otto heat engines (QOHEs) can increase by using non-thermal baths or by inhomogeneous scaling of energy levels of the working substance. Given these points, at first, we construct the coherent thermal state for

The phenomena of photon and magnon blockade, and nonclassicality which are the key ingredient for quantum enhanced technologies, can be considered as resources in quantum information processing. This paper deals with the study of nonclassicality in a

In this paper, making use of negativity, we study bipartite entanglements in a quadripartite system composed of two two-level atoms and a cavity optomechanics. An atom is inside a single-mode cavity with a movable mirror and the other one is isolated

Quantification of entanglement is important but very difficult task because, in general, different measures of entanglement, which have been introduced to determine the degree of entanglement, cannot be calculated easily for arbitrary mixed states. H

Consider the set $\mathcal{S}=\lbrace\rho_{SE}\rbrace$ of possible initial states of the system-environment, steered from a tripartite reference state $\omega_{RSE}$. Buscemi [F. Buscemi, Phys. Rev. Lett. 113, 140502 (2014)] showed that the reduced d

In this paper, an optomechanical cavity that is quadratically coupled to the cavity field and formed by a micropillar with Bragg reflectors and a thin dielectric membrane, is studied. In addition, it is considered that this interaction occurs in the

We consider a bipartite quantum system S=AB such that the part A is isolated from the environment E and only the part B interacts with E. Under such circumstances, entanglement of the system may experience decreases and increases, during the evolutio
