Entanglement is a peculiar property of quantum mechanical states that makes them quite different from classical ones. The generation, characterization, and control of entangled states is fundamental for quantum information technologies.
After a brief description on how entanglement is defined theoretically and measured practically, I will concentrate on few-qbit systems and will discuss numerical results on the entangled nature of their ground and thermal states as a function of the interaction Hamiltonian.
The presentation will mostly follow the approach described in the paper by G. Toth published in Phys. Rev. A 71 010301(R) (2005).
