Special Issue Information
Dear colleagues,
In recent years the possibility to create, manipulate, and measure single- to few-electron quantum states opened the way to the field of electron quantum optics. In this framework, conventional quantum optics tools have been properly reconsidered in order to describe the behavior of electrons ballistically propagating in mesoscopic devices. In particular, the realization of interferometers and the tomographic reconstruction of fermionic states have been among the milestones in this domain.
This branch of research has now reached a high level of maturity, making it possible to envisage the application of these propagating electronic wave-packets as flying qubits able to carry the information enclosed into a static qubit and transfer it unaffected along quantum circuits. In view of possible implementations in this direction, new effects related to the Pauli principle, many-body physics, unconventional correlation, and electron–electron interaction need to be carefully taken into account. Moreover, new experimental geometries need to be investigated in order to achieve an active optimal control over electronic wave-packets.
In this spirit, the present Special Issue is devoted to collecting the current experimental and theoretical state-of-the-art on this subject to settle a common ground for a new phases of electron quantum optics aimed at reaching an high level of control of individual electronic quantum states.

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.
