Description
This research delves into the influence of intrinsic decoherence on the
behavior of quantum correlations and coherence between two interacting qubits in a
graphene-based system. To evaluate the amount of nonclassical correlations in the
system, we employ local quantum uncertainty (LQU), and to assess quantum
coherence, we use the relative entropy of coherence (Cr) and l1-norm (Cl1). We
assume that the system is initially prepared in an extended-Werner-like (EWL) state,
and we investigate how these quantifiers evolve over time and examine their
sensitivity to various graphene layer system parameters, the mixture parameter of
the initial state, and the intrinsic decoherence rate. Our results indicate that by
adjusting the wave number operators, decreasing the intrinsic decoherence rate, and
increasing the initial state mixing parameter, it is possible to enhance both quantum
correlations and coherence within the two-dimensional honeycomb lattice system. In
addition, we found that quantum coherence is more resilient to intrinsic decoherence
than LQU, moreover, the l1-norm is more robust than the relative entropy of
coherence.
