Special Issues, Collections and Topics in MDPI journals
Open quantum systems (OQSs) are topical these days. Most notably, their study is essential within the very broad framework of quantum technologies whose full development is hindered by decoherence.
Being inherently difficult to study, OQS dynamics demand effective descriptions and models. In this respect, an emerging approach is to adopt quantum collision models (CMs), also known as repeated interactions schemes; the reservoir is simply described as a collection of smaller units with which the open system interacts one at a time.
First introduced decades ago for investigating weak measurements and micromaser dynamics and then reconsidered in the 2000s from a quantum information theory perspective, the last few years have seen a fast spread of CMs especially in research areas such as quantum non-Markovian dynamics, non-equilibrium quantum thermodynamics, quantum optics, and even gravitational decoherence.
Currently, the number of problems where a collisional approach finds application is growing. Natural questions include: To what extent are CMs a helpful tool? Can we envisage a CM-based approach for tackling potentially any OQS problem? Are there interesting applications of CMs yet unknown? In this spirit, the present Special Issue (the first fully dedicated to CMs to our knowledge) welcomes research papers where quantum CMs are effectively employed for investigating a physical phenomenon, possibly in new areas or when an advantage emerges over more conventional approaches.

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 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. 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.
