“…More detailed accounts of quantum information can be found in various books and reviews [3][4][5][6][7][8]. In a complementary paper [9] we describe the idea of entanglement and qubits, develop the concept of a general quantum state and touch on the main ideas behind quantum information itself. In that work, we made an effort to explain what are quantum correlations and how they differ from classical correlations.…”

Some of the fundamentals of quantum information science are described, including the concepts of quantum resources, quantum states and mixedness of states. The explanations are detailed and include a combination of basic facts with fully worked examples, and some more advanced topics. The principles of quantum information are illustrated with chemical examples drawn from singlet fission, photophysics of radicals, molecular excitons, electron transfer and so on. Suggestions for prospects and challenges for the field are discussed.

“…An idea for remotely preparing W states of three and four-qubit utilizing tripartite GHZ states it was presented in [181]. In [182], it was reported an efficient scheme for remote preparation of a 2 n -qubit W state via n three-qubit GHZ states. A scheme to prepare a tripartite equatorial state by using three maximally entangled GHZ states it was proposed in [183].…”

We review some current ideas about tripartite entanglement, the case representing the next level of complexity beyond the simplest one (though far from trivial), namely the bipartite. This kind of entanglement has an essential role in the understanding of foundations of quantum mechanics. Also, it allows several applications in the fields of quantum information processing and quantum computing. In this paper, we make a revision about the main foundational aspects of tripartite entanglement and we discuss the possibility of using it as a resource to execute quantum protocols. We present some examples of quantum protocols in detail.

“…Along this direction, the frozen phenomenon of coherence [32][33][34][35] and the factorization relation for coherence evolution [36] have been observed. Several theoretical studies focused on suppressing the undesirable decay of coherence [37][38][39] or generating steady-state coherence [40,41] have also been performed.…”

Quantum coherence of multiqubit states in correlated noisy channels

The long-time maintenance of quantum coherence is crucial for its practical applications. We explore decoherence process of a multiqubit system passing through a correlated channel (phase flip, bit flip, bit-phase flip, and depolarizing). The results show that the decay of coherence was evidently delayed when the consecutive actions of the channel on the sequence of qubits has some classical correlations. In particular, the relative entropy of coherence for a system with large number of qubits is more robust than that with small number of qubits. We also provide an explanation for the delayed decoherence by exploring the interplay between the change of the unlocalized quantum coherence and the total correlation gain of the multiqubit system.
