Special Issue Information
Dear Colleagues,
Quantum measurements and quantum sensing are two rapidly evolving and closely related areas of quantum physics that are currently at the forefront of research. Their scope ranges from the very foundations, establishing and testing fundamental limits on the resolution of quantum measurements, to widespread applications, not least in the area of quantum information processing, quantum communication, and quantum algorithms. On the measurement front, POVMs and weak measurements have become part of the information processing toolbox. For example, SIC POVMs have found widespread application in quantum state tomography. In the area of sensing and metrology, the quantum Fisher information, as well as the related Cramér–Rao bound, is employed to estimate the ultimate precision in quantum metrology. The aim of this Special Issue is to document the maturity of the field and, at the same time, to advance it further. This Special Issue welcomes contributions from experimentalists and theorists in these broadly defined areas. Manuscripts can be in the form of full-length research articles, reviews, or short communications. The topics to be addressed in this Special Issue include, but are not limited to, the following:
- Quantum measurements;
- Fundamental limits;
- POVMs and weak measurements;
- Continuous variable systems;
- Quantum state tomography;
- Quantum sensing and metrology;
- Quantum Fisher information;
- The Cramer–Rao bound;
- Sensor arrays.

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.
