چکیده
In this paper, we compare the saturation time scales for complexity, linear entropy and entanglement negativity two open quantum systems. Our first model is a coupled harmonic oscillator, where treat one of oscillators as bath. The second type Caldeira Leggett model, consider one-dimensional free scalar field Using these systems, discovered that both complexity purification from operator state mapping always saturated completely mixed state. More explicitly, scale types smaller than entropy. On top this, found same order model.

Decoherence and asymptotic entanglement in open quantum dynamics
In the framework of the theory of open systems based on completely positive quantum dynamical semigroups, we determine the degree of quantum decoherence of a harmonic oscillator interacting with a thermal bath. It is found that the system manifests a quantum decoherence which is more and more significant in time. We also calculate the decoherence time and show that it has the same scale as the ...

the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...

We develop a systematic method to extract the negativity in the ground state of a 1+1 dimensional relativistic quantum field theory, using a path integral formalism to construct the partial transpose ρ(A)(T(2) of the reduced density matrix of a subsystem [formula: see text], and introducing a replica approach to obtain its trace norm which gives the logarithmic negativity E=ln//ρ(A)(T(2))//. Th...
متن کاملSpin bath decoherence of quantum entanglement
We study an analytically solvable model for decoherence of a two spin system embedded in a large spin environment. As a measure of entanglement, we evaluate the concurrence for the Bell states (Einstein–Podolsky–Rosen pairs). We find that while for two separate spin baths all four Bell states lose their coherence with the same time dependence, for a common spin bath, two of the states decay fas...
متن کاملClassical complexity and quantum entanglement
Generalizing a decision problem for bipartite perfect matching, Edmonds (J. Res. Natl. Bur. Standards 718(4) (1967) 242) introduced the problem (now known as the Edmonds Problem) of deciding if a given linear subspace ofM(N) contains a non-singular matrix, whereM(N) stands for the linear space of complexN ×N matrices. This problem led to many fundamental developments in matroid theory, etc. Cla...
