Recent research in the fields related to the quantum information theory (QIT) became one of the most intriguing and promising investigations in contemporary physics. Many novel QIT concepts are discussed in the literature, and the broad range of new models of quantum optics and solid state physics are recently considered in the context of QIT. For instance, new ideas concerning optical lattices, superconducting devices, nano-resonators, circuit QED models, nonlinear Kerr-like systems were topics of the numerous papers. Such articles were devoted not only to various aspects of quantum correlations such as quantum entanglement, quantum steering, EPR correlations or quantum discord but also to more practical proposals of the systems which could be applied in the quantum teleportation, quantum coding, quantum computing, etc. On the other hand, the ideas of symmetry are widely discussed in all physical sciences. They have become keystones of various concepts and considerations leading to the novel discoveries in physics. Thus, this Special issue is devoted to the broad range of QIT topics which are related to the ideas of symmetry. We would like to invite all Colleagues to submit their original research, review and short communication articles to the issue. Both theoretical and experimental submissions are welcome.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.

Title: Single-qubit driving fields and Mathieu functions
Authors: Marco Enríquez, Alfonso Jaimes-Nájera and Francisco Delgado
Abstract: We report a new family of time-dependent single-qubit radiation fields for which the correspondent evolution operator can be disentangled in an exact way via the Wei-Norman formalism. Such fields are characterized in terms of the Mathieu functions. We show that the regions of stability of the Mathieu functions determine the nature of the driving fields: for parameters in the stable region, the fields are oscillating, being able to be periodic under certain conditions. Whereas for parameters in the unstable region the fields are pulse-like. In addition, in the stability region, this family admits solutions for evolution loops in quantum control. We get prescriptions to reach such control effect. Geometric phases in the evolution are also analyzed and discussed.
Title: Ground state entanglement witness in an open alternating spin (s=1/2) chain with XY-Hamiltonian
Authors: Alexey Pyrkov
Abstract: We have shown the existence of an energy gap in a finite open alternating chain of nuclear spins s = 1/2 with an XY-Hamiltonian for the case when total number of spins is odd and found connection between the ground state entanglement between ends of the chain and the energy gap. A comparative analysis of entanglement in a gapless homogeneous chain is carried out. Behaviour of the entanglement at low finite temperatures is also discussed.
