Symmetry Aspects in Quantum Computing

Dear Colleague,

Symmetry is a unifying concept in science and technology, its influence now extending to the flourishing field of quantum computing (QC). In fact, symmetry pervades all possible aspects of QC: formalisms, algorithms, circuits, calculations, and quantum computers. As a fast-evolving endeavor, QC challenges scientists to develop new concepts, formalisms, algorithms, and applications of symmetry theory. In this context, this Special Issue of Symmetry calls for theoretical and applied manuscripts on novel aspects of symmetry theory for QC. While manuscripts from all backgrounds are welcome, this issue highlights symmetry/QC developments relevant to general symmetry theory, quantum chemistry, quantum chemical dynamics, molecular physics, solid state physics, computer science, and computer engineering. Possible topics for this issue include (but are not limited to) the following:

1. Lie algebras and Lie groups in QC formalisms;
2. Point groups in QC formalisms;
3. Symmetry in QC encodings, mappings, and circuits (e.g., for qubit reduction);
4. Unitary group approaches for QC calculations in quantum chemistry and molecular physics;
5. Spin-adapted and spin-free QC calculations in quantum chemistry;
6. Symmetry conservation and symmetry breaking in QC calculations;
7. Symmetry-protected topological states for quantum computers;
8. Symmetry aspects of the quantum walk, Lie–Trotter–Suzuki approximation, Magnus expansion, and other propagation schemes in QC.

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-anonymized 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.
