Special Issue Information
Dear Colleagues,
In metrology, nonlinear interferometers present a versatile technique for sensitive phase measurements and form the basis for detecting gravitational waves. Such interferometers contain nonlinear elements (parametric down-conversion, four-wave mixing) instead of conventional beam splitters, and have many advantages over their linear counterparts in terms of measurement accuracy, state engineering and loss resistance. Nonlinear interferometers can be realized in different geometries and produce quantum light with various spectral and spatial profiles, mode structure and orbital angular momenta. At the same time, due to strong correlations between signal and idler photons generated within such interferometers, they are promissing tools for testing the symmetry of objects, their chirality, and can be used in many quantum applications, from quantum imaging to quantum communication and quantum cryptography.
This Special Issue, “Quantum nonlinear interferometers”, will feature articles with a broad scope of research on the properties of nonlinear interferometers and their applications in metrology and other branches of science.

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. Symmetry 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 2400 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.
