Thermal 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 کاملThree-Qubit Ground State and Thermal Entanglement of XXZ Model With Dzyaloshinskii-Moriya Interaction
We have studied the symmetric and non-symmetric pairwise ground state and thermal entanglement in three-qubit anisotropic Heisenberg (XXZ) and Ising in a magnetic field models and in the presence of Dzyaloshinskii-Moriya (DM) interaction. We have found that increasing of the DM interaction and magnetic field can enhance and reduce the entanglement of system. We have shown that the non-symmetric...
متن کاملGround-state entanglement of the BCS model.
The concept of local concurrence is used to quantify the entanglement between a single qubit and the remainder of a multiqubit system. For the ground state of the BCS model in the thermodynamic limit the set of local concurrences completely describes the entanglement. As a measure for the entanglement of the full system we investigate the average local concurrence (ALC). We find that the ALC sa...
متن کاملGround state entanglement and geometric entropy in the Kitaev model
We study the entanglement properties of the ground state in Kitaev’s model. This is a two-dimensional spin system with a torus topology and non-trivial four-body interactions between its spins. For a generic partition (A,B) of the lattice we calculate analytically the von Neumann entropy of the reduced density matrix ρA in the ground state. We prove that the geometric entropy associated with a ...
متن کاملGround State Entanglement in One Dimensional Translationally Invariant Quantum Systems
We examine whether it is possible for one-dimensional translationally-invariant Hamiltonians to have ground states with a high degree of entanglement. We present a family of translationally invariant Hamiltonians {Hn} for the infinite chain. The spectral gap of Hn is Ω(1/poly(n)). Moreover, for any state in the ground space of Hn and anym, there are regions of sizem with entanglement entropy Ω(...
