Intrinsic decoherence effects on quantum correlations dynamics

Intrinsic decoherence dynamics and dense coding in dipolar spin system

“…where E m(n) denote the eigenvalues of H and ϕ m(n) their corresponding eigenvectors. Recently this way of analysis was performed on physically relevant systems [12][13][14][15][16][17][18].…”

“…Also, the dynamics of quantifiers based on skew information such as LQU and uncertaintyinduced nonlocality (UIN) were studied by considering two-qubit spin models as resource [16]. The influence of intrinsic decoherence on the quantum correlations was quantified by logarithmic negativity and TDD in a two-qubit Heisenberg XYZ spin chain in the presence of the z-DM interaction [17]. The dynamics of Bell nonlocality, entanglement and entropic uncertainty were studied under intrinsic decoherence in a two nearest spin-1/2 Heisenberg XYZ model subjected to a transverse uniform magnetic field and under the interplay of DM along with Kaplan-Shekhtman-Entin-Wohlman-Aharony (KSEA) interactions [18].…”

Intrinsic decoherence dynamics in the three-coupled harmonic oscillators interaction

“…The last decade has been very prolific in this field we want to board, the community has taken the task to study a vast amount of systems that can experience intrinsic decoherence. We can see research on quantification of non-classicality [9], qubits for quantum information processing [10], bipolar spin systems [11], quantum dot correlations [12], Heisenberg XYZ spin chains, quantum-memory-assisted two-qubit, and the temporal evolution of quantum correlations [13,14,15], quantum-memory-assisted entropic uncertainty, mixedness, and entanglement dynamics in two-qubit system [16], symmetric spin-orbit model [17], two-qubit quantum Fisher information [18], two-qubit maximally entangled Bell states [19], trapped ions [20], isolated Heisenber and Aubry-André spin models [21], two coupled quantum dots [22], N-level atomic system [23], two-coupled qubit two-level cavity [24], twolevel atom [25], state transfer in spin channels [26], Heisenber anisotropic interaction [27], nonlocal advantage of quantum coherence [28], qutrit teleportation [29], and quantum dense coding [30]. When we look at specific examples related optomechanical systems, we find notable works on Jaynes-Cummings under intrinsic decoherence [31,32,33], bimodal multiquanta Jaynes-Cummings [34], entanglement two Tavis-Cummings (no-RWA JC) [35], and ultra-strong coupled harmonic oscillator in cavities [36].…”

Influence of deformed cavity field and atomic dipole interaction on the quantum correlations of two-qubit system

“…The non-classicality and the non-locality of two-qubit Werner state and two-qutrit under the effect of some classical noise environment have been discussed (Rahman et al 2022a, b). Some quantum correlations dynamics features of Bell nonlocality, entanglement and entropic uncertainty of Dzyaloshinskii-Moriya (DM), Kaplan-Shekhtman-Entin-Wohlman-Aharony(KSEA) interactions with external magnetic field, and intrinsic decoherence have obtained (Abd-Rabboul et al 2021;Hashem et al 2022;Essakhi et al 2022). The concurrence is a simple measure of entanglement that provides an analytic formula for the entanglement of formation (EoF) which is one of three widely studied measures of entanglement of a general bipartite system (Wootters 2001).…”
