Effect of decoherence from a spin environment on the entanglement dynamics of two-qutrit states

Abstract

The entanglement dynamics of a two-qutrit system under decoherence from a spin environment is investigated by using negativity as entanglement measure. Our results imply that the entanglement evolution depends not only on the coupling strength and the tunneling elements of the environment but also on the number of the freedom degrees and the initial state of the environment. entanglement dynamics, quantum decoherence, a spin environment PACS: 03.67.Mn, 03.65.Yz

Quantum Correlations in Ising-XY ZDiamond Chain Structure under an External Magnetic Field

“…In this paper, we refer to this particular geometric measure as trace distance discord (TDD). In last years, with the development of quantum information and quantum computation, spin systems have an extensive application in the field of quantum information [11,12]. Heisenberg model, as the simplest spin chain, has been researched in many fields of quantum information and computation.…”

“…In recent years, spin systems have an extensive application in the field of quantum information. [23,24] The Heisenberg model has been researched in many fields of quantum information and computation. It can be implemented in many physical systems such as quantum dot system, [6] nucleus system, [25] electronic spin system [26] and optical lattices system.…”

Quantum discord and one-norm geometric quantum discord for XXX Heisenberg spin chain under noisy channels

“…However, this problem can be worked out if Schatten 1-norm (trace norm) is utilized as a distance measure [16,17,18]. In recent years, with the progress of quantum information and quantum computation, spin system applies in the field of quantum information widely [19,20]. Heisenberg model (as the simplest spin chain) has been investigated in many subjects of quantum information and computation.…”

Critical behavior of the XY spin chain with three-site interaction studied in terms of the Loschmidt echo

“…Quantum spin chains play a fundamental role in studying many-body systems. For instance, entanglement in general and in spin chains has attracted much attention [22][23][24]. QPT in spin chains is also studied widely [7,9,10].…”
