Abstract

We consider the high-probability state transfers and entanglements between different nodes of the spin-$1/2$ chains governed by the $\mathit{XXZ}$ Hamiltonian using the inhomogeneous stationary external magnetic field. Examples of three-, four-, ten- and twenty-node chains are represented. A variant of realization of the proper inhomogeneous magnetic field is discussed.

High-Probability Quantum State Transfer between nodes of an Open Chain of 1/2 Spins with ${XXZ}$ Hamiltonian

Edward B. Fel’dman, Alexander Ivanovich Zenchuk

This paper concerns the problem of the high probability state transfer (HPST) among different nodes of the chains of 1/2-spins with the ${XXZ}$ Hamiltonian. This effect is possible due to the suitably distributed weak bonds in the chain. We show that the arbitrary initial state may be transfered with the high probability to any node of the four-node chain with strong end bonds. Varying bonds in the six-node chain one can provide the HPSTs among two end nodes and two symmetrically placed inner nodes. We also construct the eight-node chain with the HPSTs among all of them.

High-probability state transfer in spin- 1/2 chains: Analytical and numerical approaches

Edward B. Fel’dman, E. I. Kuznetsova, Alexander Ivanovich Zenchuk

This article is devoted to the development of analytical and numerical approaches to the problem of the end-to-end quantum state transfer along the spin-1/2 chain using two methods: (a) a homogeneous spin chain with week end bonds and equal Larmor frequencies and (b) a homogeneous spin chain with end Larmor frequencies different from inner ones. A tridiagonal matrix representation of the $\mathit{XY}$ Hamiltonian with nearest neighbor interactions relevant to the quantum state transfer is exactly diagonalized for a combination of the preceding two methods. In order to take into account interactions of the remote spins, we used numerical simulations of the quantum state transfer in 10-node chains. We compare the state transfer times obtained using the two preceding methods for chains governed by the both $\mathit{XY}$ and $\mathit{XXZ}$ Hamiltonians and using both nearest neighbor and all-node interactions.

Relationship between probabilities of the state transfers and entanglements in spin systems with simple geometrical configurations

Serge I. Doronin, Edward B. Fel’dman, Alexander Ivanovich Zenchuk

In this paper we derive analytical relations between probabilities of the excited state transfers and entanglements calculated by both the Wootters and positive partial transpose criteria for the arbitrary spin system with single excited spin in the external magnetic field and Hamiltonian commuting with ${I}_{z}$. We apply these relations to study the arbitrary state transfers and entanglements in the simple systems of nuclear spins having two- and three-dimensional geometrical configurations with $XXZ$ Hamiltonian. It is shown that high-probability state transfers (HPSTs) are possible among all four nodes placed in the corners of the rectangle with the proper ratio of sides as well as among all eight nodes placed in the corners of the parallelepiped with the proper ratio of sides. Entanglements responsible for these HPSTs have been identified.

Entanglement in a two-spin (1/2, 3/2) mixed-spin Heisenberg XXZ chain with an inhomogeneous external magnetic field

Ke-Tao Guo, M. M. Liang, Hong-Yu Xu +1 more

Using the concept of negativity, we investigate the thermal entanglement of a two-spin (1/2, 3/2) mixed-spin Heisenberg XXZ chain with an inhomogeneous external magnetic field. We obtain the analytical results of entanglement of this model. For the case of uniform magnetic field, we find that the critical temperature increases with the increase of the anisotropy parameter k , and for the same couplings, the critical temperature is higher than the results of the spin-1/2 XXZ chain and (1/2, 1) mixed-spin XXZ chain. Evidence of the quantum phase transition is found, and by adjusting the inhomogeneous magnetic parameter b , one is able to obtain more entanglement at higher temperature.

Ground-State Entanglement and Mixture in an XXZ Spin Chain

Wang Cheng-Zhi, Chun-Xian Li, Guo Guang-Can

We study the pairwise entanglement and mixture of a three-qubit XXZ spin chain in the ground state in the presence of an external magnetic field B . The effects of the magnetic field, the anisotropy and the temperature on the entanglement and mixture are considered, and entanglement versus the mixture of all the two-spin states is investigated. We find that the maximal entangled mixed state can be obtained in the considered system by controlling the magnetic field. Our results provide another way to generate maximally entangled mixed states.
