Quantum has been assigned an International Standard Serial Number (ISSN) by the ISSN International Centre.
The ISSN is similar to the more widely known ISBN, which is used to uniquely identify books. The ISSN achieves the same, but for periodically appearing publications, like journals. Quantum is thus from now on uniquely identified by its ISSN 2521-327X.
Having obtained an ISSN enables us to proceed with developing Quantum further and will allow us to apply for inclusion in the Web of Science and the Directory of Open Access Journals.
Papers already published in Quantum (and the respective .bib files) have been updated to include the ISSN.
