The Bounds and Limits of Quantum System: Perspective and Development

Dear Colleagues,

Physical bounds/limits, such as quantum speed limits, bounds on entropy production, the Carnot limit, the standard quantum limit, the Heisenberg limit, etc., provide insights into quantum technologies such as quantum computation, quantum heat engines, and quantum metrology.

In this Topic, we hope to provide a broad overview of the physical bounds/limits of quantum systems. This Topic aims to span the fundamental interpretations of different physical bounds/limits; the formalisms of different quantum limits/bounds, as an alternative way of understanding quantum physics; and the gained intuition and superiority of different quantum limits/bounds to meet the increasing demand of quantum technologies in developing quantum enhanced protocols by exploiting nonclassical resources of the quantum realm.

We welcome researchers to contribute Original Research and Review papers. The potential topics include, but are not limited to:

• Quantum speed limits;
• Bounds on entropy production;
• Bounds for quantum algorithms;
• Bounds on quantum gate complexity;
• Limits of quantum heat engines;
• Limits of quantum metrology.

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 250 words) can be sent to the Editorial Office for assessment.

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.
