Special Issue Information

Dear Colleagues,

Recent years have witnessed an explosive growth of quantum science and technology along the major pillars of quantum computation, quantum sensing and metrology, quantum communication and quantum simulation. This growth has mostly focused on engineered quantum systems comprising well-defined qubits and a relatively clear distinction between the quantum system and its decohering environment.

Interestingly, this growth has transcended its traditional “technological” confines into more complex systems, biological systems being a most unanticipated example. Quantum biology, in particular, has in recent years advocated the existence of quantum coherent effects in complex biological systems. These are accounted for by virtually the whole conceptual machinery of quantum information science. In this respect, biological systems can be used for quantum metrology, e.g., for magnetic sensing. In turn, from a dual perspective, quantum systems can be used as bio-sensors. Both approaches have the promise to coalesce into an even more unanticipated synthesis of “quantum” and “bio”.

However, complex systems are not limited to biological systems. Some prominent examples of complex systems explored with the tools of quantum information and quantum metrology are quantum networks, quantum many-body systems and biomimetic engineered quantum systems (e.g., artificial light harvesters).

All such systems pose tremendous challenges exactly because of their complex nature and their very large number of coupled degrees of freedom disguising or obscuring, if not completely suppressing, the underlying quantum dynamics. The clear distinction of system versus environment, quantum benchmarking (i.e., the ability to precisely discern genuinely quantum from classical behavior and define any operational advantage of the former), quantum dynamics formulations, and precise experimental control, are just a few of the challenges faced by scientists expanding the conceptual and experimental tools of quantum science into the realm of complex systems.

The goal of this Special Issue is to further explore the synthesis of quantum information and quantum metrology with complex systems. Our optimistic working assumption is that, while complex systems pose daunting difficulties, at the same time they offer a rich spectrum of unchartered possibilities for both deepening our understanding of quantum science and producing novel technology, thereby pushing the quantum advantages to the mesoscopic or even macroscopic scale.

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. 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 1600 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.
