Open Quantum Systems (OQS) for Quantum Technologies

Dear Colleagues,

Coherent quantum dynamics, a crucial ingredient of all quantum technologies, is hindered by the unavoidable coupling of quantum systems to the external environment. The latter, by “reading” the state of the system, prevents quantum interference. A deep understanding and full characterization of the open dynamics of a quantum system is therefore of the utmost importance from the viewpoint of fundamental physics as well as the implementation of quantum devices.
We have witnessed great progress in the study of open quantum systems in the past few years, ranging from a better understanding of the role played by quantum information flux from the system to the environment in the emergence of classical behavior, to a fuller characterization of the quantum memory effect, to the role of the system–environment exchange of quantum information in quantum thermodynamics. Furthermore, it has been shown that decoherence effects are helpful in some specific tasks or phenomena, such as excitation transfer in complex quantum networks and in quantum biological systems. Finally, the engineering of the environmental degrees of freedom by techniques ranging from dynamical decoupling to optimal control to environment confinement have proved to be formidable tools in the design of efficient quantum devices.

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 submissions that pass pre-check are 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 250 words) can be sent to the Editorial Office for assessment.

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. Entropy is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
