Thermal Entanglement in the Two-qubit Heisenberg Xyz Model
We study the entanglement of a two-qubit one dimensional XYZ Heisenberg chain in thermal equilibrium at temperature T. We obtain an analytical expression for the concurrence of this system in terms of the parameters of the Hamiltonian and T. We show that depending on the relation among the coupling constants it is possible to increase the amount of entanglement of the system increasing its anis...
متن کاملThermal entanglement in three-qubit Heisenberg models
Over the past few years much effort has been put into studying the entanglement of multipartite systems both qualitatively and quantitatively. Entangled states constitute a valuable resource in quantum information processing [1]. Quite recently, entanglement in quantum operations [2–4] and entanglement in indistinguishable fermionic and bosonic systems [5–7] have been considered. Entanglement i...
متن کاملThermal and ground-state entanglement in Heisenberg XX qubit rings
Quantum entanglement is an important prediction of quantum mechanics and constitutes indeed a valuable resource in quantum information processing [1]. Much efforts are devoted to the study and characterization of it. Very recently one kind of natural entanglement, the thermal entanglement [2–7], is proposed and investigated. The investigations of this type of entanglement, groundstate entanglem...
متن کاملAnalytical results for entanglement in the five-qubit anisotropic Heisenberg model
We solve the eigenvalue problem of the five-qubit anisotropic Heisenberg model, without use of Bethe’s ansatz, and give analytical results for entanglement and mixedness of two nearest-neighbor qubits. The entanglement takes its maximum at ∆= 1 (∆> 1) for the case of zero (finite) temperature with ∆ being the anisotropic parameter. In contrast, the mixedness takes its minimum at ∆= 1 (∆> 1) for...
متن کاملAnisotropy and magnetic field effects on the entanglement of a two qubit Heisenberg XY chain.
We investigate the entanglement of a two-qubit anisotropic Heisenberg XY chain in thermal equilibrium at temperature T in the presence of an external magnetic field B along the z axis. By means of the combined influences of anisotropic interactions and a magnetic field B, one is able to produce entanglement for any finite T, by adjusting the magnetic field strength. This contrasts with the isot...
