Abstract The effect of nonlinearity, initial atomic state, and different resonance cases on the interaction between nonlinear SU (1, 1) quantum states a two-level atom is discussed. optimal behaviours decoherence, entanglement coherence are predicted via using skew information, tomographic entropy, relative entropy coherence, respectively. It shown that detuning parameter has destructive conseq...

in iranian language learning contexts, writing in english is an important challenge for learners, since it is usually treated as a secondary skill and is led to the periphery of language classes, due to its time-consuming nature. computer technology and namely the free online environments available in the world wide web (www) offer possibilities for moving beyond such confinements. asynchronous...

The routine definitions of Shannon entropy for both discrete and continuous probability laws show inconsistencies that make them not reciprocally coherent. We propose a few possible modifications of these quantities so that 1) they no longer show incongruities, 2) they go one into the other in a suitable limit as the result of a renormalization. The properties of the new quantities would slight...

We establish two complementarity relations for the relative entropy of coherence in quantum information processing, i.e., quantum dense coding and teleportation. We first give an uncertainty-like expression relating local quantum coherence to the capacity of optimal dense coding for bipartite system. The relation can also be applied to the case of dense coding by using unital memoryless noisy q...

BACKGROUND Significant advances have been made in our understanding of subcortical processes related to anesthetic- and sleep-induced unconsciousness, but the associated changes in cortical connectivity and cortical neurochemistry have yet to be fully clarified. METHODS Male Sprague-Dawley rats were instrumented for simultaneous measurement of cortical acetylcholine and electroencephalographi...

We show how a vortex structure manifests itself in the one-dimensional projection of a vortex field. We calculate the extent of spatial coherence and entropy of such projections. We quantify the spatial coherence and discuss the properties of the Wigner functions for the projected field.

Based on the resource theory for quantifying coherence of quantum channels, we introduce a new quantifier channels via maximum relative entropy. We prove that entropy is directly related to maximally coherent under particular class superoperations, which results in an operational interpretation channels. also conception sub-superchannels and sub-superchannel discrimination. For any show advanta...

Coherence is a cornerstone of quantum theory and prerequisite for the advantage technologies. In recent work, notion coherence with respect to general measurement, i.e., positive operator-valued measure (POVM), was introduced embedded into resource-theoretic framework that generalizes standard resource coherence. particular, POVM-incoherent (free) states operations were established. this we exp...

As the precious resource for quantum information processing, quantum coherence can be created remotely if the involved two sites are quantum correlated. It can be expected that the amount of coherence created should depend on the quantity of the shared quantum correlation, which is also a resource. Here, we establish an operational connection between coherence induced by steering and the quantu...

We find that a bipartite quantum state is entangled if and only it coherent with respect to complete bases of states in the corresponding system are distinguishable under local operations classical communication.
