Hierarchies of localizable entanglement due to spatial distribution of local noise

چکیده

Complete characterization of a noisy multipartite quantum state in terms entanglement requires full knowledge how the content is affected by spatial distribution noise state. Specifically, we find that if measurement basis protocol computing localizable and Kraus operator representing local channel do not commute, information regarding retained system even after qubit traced out measurement. Using this result basic properties under noise, present set hierarchies over specific subsystem multiqubit can obey when acts on subparts or all qubits whole system. In particular, propose two types hierarchies---one tailored according to number unmeasured qubits, other one depends additionally cardinality measured leading classification states. We report percentage states satisfying proposed case random three- four-qubit systems show, using both analytical methods numerical simulations, almost cases, anticipated tend hold with variation strength noise.

Limitation of entanglement due to spatial qubit separation

– We consider spatially separated qubits coupled to a thermal bosonic field that causes pure dephasing. Our focus is on the entanglement of two Bell states which for vanishing separation are known as robust and fragile entangled states. The reduced two-qubit dynamics is solved exactly and explicitly. Our results allow us to gain information about the robustness of two-qubit decoherence-free sub...

Localizable Spectrum and Bounded Local Resolvent Functions

Given a Banach space operator with interior points in the localizable spectrum and without non-trivial divisible subspaces, this article centers around the construction of an infinite-dimensional linear subspace of vectors at which the local resolvent function of the operator is bounded and even admits a continuous extension to the closure of its natural domain. As a consequence, it is shown th...

Spatial modelling of railway noise propagation

In recent decades, population growth and progress of technology have shaped large and compact urban settlements. Existence of huge transportation systems and developed urban infrastructures are among the most important properties of modern cities. In spite of prompt transit and facilitated daily activities, development of transportation systems causes many problems, including traffic, air and n...

Effect of random telegraph noise on entanglement and nonlocality of a qubit-qutrit system

We study the evolution of entanglement and nonlocality of a non-interacting qubit-qutrit system under the effect of random telegraph noise (RTN) in independent and common environments in Markovian and non-Markovian regimes. We investigate the dynamics of qubit-qutrit system for different initial states. These systems could be existed in far astronomical objects. A monotone decay of the nonlocalit...
