Special Issue Information
Dear Colleagues,
The first quantum revolution—the understanding of the physical laws in the microscopic, quantum realm—created all the core technologies of our modern society. Nowadays, the possibility of manipulating individual quantum systems has paved the way for the second quantum revolution, which aims to fully harness quantum phenomena to develop radically new quantum technologies.
Quantum walks (QWs)—the quantum counterpart of classical random walks—are a concept as simple as they are powerful: They describe the propagation of a quantum particle over a discrete space subject to given constraints. A rich plethora of different QWs have stemmed from such a seminal idea, such as continuous or discrete time, chiral, lackadaisical, stochastic, topological, etc., denoting an increasing interest in the topic from several research areas and a diversification of possible applications.
Their versatility and peculiar quantum features have made them paradigmatic models in quantum technologies. In recent years, QWs have been widely used in modelling the transport of excitation and information across networks, and they have proven to be a universal model for quantum computation and to provide speed-up in quantum algorithms, for e.g., spatial search. Proposals of quantum communication protocols and public-key cryptographic systems based on QWs have been put forward, in addition to their use as quantum probes and as quantum simulation schemes having been foreseen.
In this spirit, the present Special Issue is devoted to presenting the current theoretical and experimental state of the art surrounding the role of QWs in the four leading areas of quantum technologies. Original unpublished research articles and review articles are therefore invited on these topics:
(i) Quantum communication;
(ii) Quantum computation;
(iii) Quantum simulation;
(iv) Quantum metrology, sensing, and imaging;
(v) Quantum control;
(vi) Quantum software and theory;
topics (v) and (vi) have been included as they are both important areas of research that cut across all four leading areas (i–iv).

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.
