Controlling average steered coherence in the spin-1 Heisenberg models

Abstract

Abstract Average steered coherence (ASC) reflects the nonlocal property of a state from a fundamental aspect and the steerable states achieve a nonlocal advantage of quantum coherence (NAQC) when the ASC exceeds a threshold. We explore the ASC in both the spin-1 XXZ model with Dzyaloshinskii–Moriya (DM) and Kaplan–Shekhtman-Entin–Wohlman–Aharony (KSEA) interactions and the dimerized XXZ model. For the first model, it is found that the ASC in the thermal state can be enhanced by tuning the anisotropic parameter and the DM and KSEA interactions; while for the second model, the ASC can be enhanced by tuning the J 2 interaction and there exists a temperature plateau at which it remains almost the constant. Besides, for both the spin-1 models, a NAQC can always be achieved by optimizing the involved controlling parameters.

Enhancing steered coherence in the Heisenberg model using Dzyaloshinsky–Moriya and Kaplan–Shekhtman–Entin-Wohlman–Aharony interactions

Yu-Xia Xie, Xinyu Liu

Abstract Steered coherence characterizes the ability of one party to steer the coherence of another when they share a bipartite state. It is crucial to control its strength so as to use it as a resource for practical applications. We investigate average steered coherence (ASC) in the Heisenberg XXZ model. It is found that for the thermal state at finite temperature, the ASC can always be noticeably enhanced by adjusting the Dzyaloshinsky–Moriya and Kaplan–Shekhtman–Entin-Wohlman–Aharony interactions. There are also parameter regions in which the ASC approaches to its maximum. This result suggests an alternative for manipulating ASC in a spin system.

Nonlocal advantage of quantum coherence in the spin-1/2 and spin-1 Heisenberg XXZ models

Yu-Xia Xie, Yuhan Zhang

Abstract Quantum coherence underlies different forms of quantum correlations. We investigate the nonlocal advantage of quantum coherence (NAQC) for the thermal equilibrium states of both the spin-1/2 and the spin-1 Heisenberg XXZ models. By considering the NAQC formulated within two slightly different frameworks, we showed that their values can always be enhanced by tuning strength of the spin-exchange interaction along the z direction. The maximum achievable NAQC by tuning decreases with the increasing temperature T and there will be no NAQC when T is higher than a critical value. Moreover, both the NAQC and the critical temperature could be further noticeably increased by introducing the Dzyaloshinsky–Moriya interaction along either the z direction or the x direction to the considered spin models.

Impurity-assisted control of the nonlocal advantage of quantum coherence in the Heisenberg model

Yu-Xia Xie, Yun-Yue Gao

Abstract Quantum coherence is not only a fundamental notion in quantum theory but also an invaluable resource for quantum information processing. We investigate the nonlocal advantage of quantum coherence (NAQC) in the Heisenberg model, aimed at seeking flexible ways for its control. By considering impurities, or more explicitly, the inhomogeneous spin couplings and nonuniform magnetic field, in such a model, we showed that an efficient nonlocal control of the NAQC can be realized, and there exists a wide impurity parameter region for which the NAQC takes the value a little less than its maximum 1. Moreover, the critical temperature after which the NAQC vanishes can also be enhanced evidently by tuning the impurity parameters.

Quantum steering in Heisenberg models with Dzyaloshinskii–Moriya interactions

Huizhen Li, Rong-Sheng Han, Ye-Qi Zhang +1 more

In this work, we study the quantum steering in two-qubit Heisenberg models with Dzyaloshinskii–Moriya (DM) interaction and an external magnetic field. We find that the steerable weight (SW) and the critical temperature where SW → 0 can be enhanced by the DM interactions. In the special case where the magnetic field is vanishing and the two spins are ferromagnetically coupled, the DM interaction can tune the zero-temperature SW from zero to a finite value. In addition to the SW, some other measurements used to identify the quantum entanglement and quantum correlations are investigated, i.e. , the concurrence, the quantum discord, and the robustness of coherence. In the strong magnetic field limit, our results show that the SW is dramatically different from the other measurements.

Characterizing quantum nonlocalities under the Heisenberg XYZ spin model with Dzyaloshinskii–Moriya interaction

Ling-Ling Xing, Huan Yang, Zong Xu +4 more

Abstract In quantum information science, the nontrivial applications of the Heisenberg spin model are to realize quantum communication and quantum computing using the quantum nonlocalities between particles in the spin chain. Here, considering Heisenberg XYZ spin model with Dzyaloshinskii–Moriya (DM) interaction, our attentions are directed to ascertain the nonlocal advantage of quantum coherence (NAQC), and also characterize the Bell nonlocality (BN). As revealed from the results, one can use low temperature to realize situations in which the NAQC and BN are invariant. The NAQC and BN cannot be detected if temperature is high. External temperature strongly influences the two quantum nonlocalities in ferromagnetic systems. The strong coupling parameter ℑ x brings on the fact that the two quantum nonlocalities are invariant. It is very difficult to capture the NAQC and BN if ℑ x is weak. Considering ℑ y > 0 , the strong ℑ y is responsible for freezing quantum nonlocalities, and one cannot witness the NAQC when ℑ y is low. Moreover, the freezing of quantum nonlocalities can be achieved via enhancing ℑ z , and the detection of NAQC is difficult if ℑ z is weak. Of particular note, under the influence of DM interactions, NAQC (BN) cannot (can) be frozen both in antiferromagnetic and ferromagnetic systems. The strong D y and D z give rise to the difficulty of capturing the NAQC.
