Terms and conditions

By submitting a manuscript to Quantum, you agree with Quantum’s terms and conditions. In particular, you certify that:

  • you have the permission of all co-authors and other right holders to pursue publication of the work in Quantum,
  • you are not infringing on anyone’s copyright with the material contained in your work,
  • you will be fully liable for any charges resulting from copyright infringement, and
  • you will not submit this work to any other publishing venue unless it is terminally rejected by Quantum (special rules for conference proceedings apply, see below).

In addition, authors, referees and members of all boards of Quantum commit to follow the Code of Conduct laid out here.

The above summary is just for informative purposes. The binding terms and conditions follow.

1. Preamble and definitions

Access to Quantum is subject to the following terms and conditions, which constitute a contract between Quantum and any user. By engaging in any form of interaction with Quantum or its members, the user accepts these terms and conditions in full.

We denote by “Quantum” the Association for the Promotion of Open Access Publishing in Quantum Science, legally known as

Verein zur Förderung des Open Access Publizierens in den Quantenwissenschaften

Boltzmanngasse 3, 1090 Wien, Austria

(ZVR-Zahl 941922539),

the journal Quantum, the website quantum-journal.org, and the online system provided to organize submission and peer review of works, as well as Quantum’s social media accounts.

We denote by “user” any person accessing, using, exchanging, downloading, or submitting any type of content or information with, from and to Quantum and all services it provides, interacting with Quantum in any way, or holding or exercising any function within Quantum.

A “work” submitted to Quantum refers to the actual manuscript as publically available on arxiv.org (“the arXiv”), as well as all supporting material, such as, but not limited to, appendices, supplementary information, a popular summary, datasets, computer code, images, plots, videos or other recordings that are transmitted or made available to Quantum in order to assess the manuscript’s suitability for publication. This refers to both the manuscript and material present in the initial submission, as well as all further versions and additions of material in later resubmissions.

The “submitter” is anyone who carries out the submission of a work to Quantum for publication, either through the provided online system or via email, and who is identified by their account in the online system or name and address used in the email. In case of multiple submitters, the definition applies in full to every single one of them.

2. Code of conduct

Quantum fosters scientific integrity and ethical conduct. Consistent with the bylaws of Quantum (such as the constitution of the Verein zur Förderung des Open Access Publizierens in den Quantenwissenschaften), its code of conduct upholds those values, detailing the ethical guidelines and expectations for participation in Quantum. Authors, referees, editors, all board members and all other users of Quantum are expected to act at all times in accordance with the principles and standards described in this code.

Unacceptable behaviour

In particular, the code of conduct specifies behaviour that Quantum deems unacceptable, both in interactions with Quantum and in professional life in general. This includes but is not limited to:

  1. Plagiarism and fabrication of data and results, including misrepresentation of contributions and authorship, selective reporting, failure to promptly correct errors, or theft of data and/or other research materials, as well as misrepresentation and overstatement of results and the omission of crucial conditions and assumptions.
  2. Publication (or submission for publication) of works submitted to or published in Quantum to other publishing venues, unless the work is terminally rejected by Quantum. “Other publishing venues” include other journals and conference proceedings, but exclude public pre-print servers such as the arXiv and personal or institutional websites of the authors. Re-publication of excerpts or the entirety of a work submitted to or published in Quantum as part of a work with a broader scope, such as a review article of thesis, is explicit allowed.
  3. Subversion of peer review, including failure to declare conflict of interest, failure to recuse under conflict of interest, misuse of information during review, unnecessarily delaying the peer-review process, violation of the anonymity of referees, premature solicitation of press coverage, corruption and/or bribery.
  4. Impersonation of other persons or entities, as well as unrightfully claiming the ownership of scientific titles, professional positions, or affiliations.
  5. Using Quantum or any other system for the dissemination of scientific works to promote hate or discriminatory speech, or to infringe on the rights of others.
  6. Sharing of confidential information, such as the identity of reviewers, referee reports, and other internal correspondence to persons not involved in the peer-review process.
  7. Discrimination of any kind, such as on the basis of religion, disability, age, national origin, race, ethnicity, sexual orientation, gender identity, or gender expression. Discrimination includes the use of derogatory comments or slurs.
  8. Harassment, including bullying and intimidation, false accusations, threats and assault, as well as sexual harassment in public or in private.
  9. The violation of public trust, including making false or misleading statements, to media, and misrepresentation to grant and/or funding agencies.

Reporting and investigation

Quantum may learn of violations through reports from witnesses or aggrieved individuals and parties, including anonymous reports filed through the dedicated online form. For the safety of all reporters, once a report has been made, Quantum editors and board members are bound to maintain the confidentiality of the report except as explicitly requested by the reporting parties. Upon receiving a report, Quantum will progress as follows:

  1. The Executive Board of Quantum will name an investigator or form a small investigation body of no more than three people, each of whom must be free of conflict of interest.
  2. The investigator or investigating body may solicit additional information from the reporter, with the goal of reaching a tentative conclusion over the course of two weeks.
  3. The tentative conclusion of the investigating body will be delivered to the Steering Board, along with a suggested resolution action as described in the section below.
  4. If the tentative conclusion and suggested resolution action are agreed upon by the Steering Board, Quantum will inform the reporter of their decision and seek agreement before proceeding.
  5. The party suspected of a violation of the code of conduct will be informed of the allegations and planned resolution action and given 20 working days to respond.
  6. Depending on the findings, on communication from the involved parties, and consensus of the Steering Board, the resolution action may be implemented or further investigations carried out with the aim of resolving the situation.

During the reporting and investigating process, all individuals must exercise all due diligence to prevent divulging any report details beyond those strictly necessary to enact and uphold the code of conduct. In particular, if upon receiving an initial report, it is deemed the alleged infraction would not result in a penalty more severe than a formal warning, the Executive Board may decide to directly handle the report without the aid of an investigating body, provided that no conflict of interest is introduced.

Enforcement and penalties

If a Quantum user is found through the preceding process to have committed any violation of the code of conduct, Quantum may enforce the code of conduct in a number of different ways. An appropriate resolution is decided by the Steering Board, taking into account all factors, and having as a goal to improve the situation. Possible actions to enforce the code of conduct include but are not limited to:

  1. A formal (written) warning made to the infringing party.
  2. Requiring the infringing party to make a formal (written) apology.
  3. Reporting the infringing party to their home institutions, employers, and/or professional societies.
  4. Reporting the infringing party to the relevant authorities, in case of suspicion of criminal offences.
  5. Retraction of compromised manuscripts (based on scientific reasons).
  6. Refusal to consider future manuscripts from the infringing party.
  7. Expulsion from the Steering, Executive or Editorial Board.

3. Submission and publication of works

Works submitted to Quantum undergo the peer-review process following the Editorial Policies of Quantum. This process ends with either the acceptance of the work for publication, or the terminal rejection of the work.

Responsibilities of the submitter

By submitting a work to Quantum, the submitter warrants all of the following points and assumes full responsibility and liability for any costs and damages resulting directly or indirectly from any of them being untrue:

  1. The submitted work is an original creation of the authors listed on the manuscript, and all listed authors have made substantial contributions to the creation of the work.
  2. The submitter has the permission of all authors and all other copyright and intellectual property rights holders to pursue the publication of the work in Quantum, and to grant Quantum all the rights specified in these terms and conditions.
  3. The manuscript is publicly accessible on the arXiv in the section quant-ph, or at least crosslisted to quant-ph.
  4. The work has not been previously published in any other journal or publishing venue, except in conference proceedings and on public pre-print servers such as the arXiv or the authors’ personal or institutional websites. Works previously published in conference proceedings must substantially differ from or expand upon the conference version (for example contain previously omitted proofs) and indicate the previous publication on the first page of the manuscript. An example is when the proceedings contain only an extended abstract of the work, without technical proofs.
  5. The submitter has obtained permissions to grant Quantum the rights specified in these terms and conditions for all material contained in the work and has included appropriate credits and prominently marked or indicated any rights held by third parties.
  6. The submitter has clearly informed Quantum at the time of submission of any parts of the work which, due to copyright or other constraints, cannot be published by Quantum under the Creative Commons Attribution 4.0 International (CC BY 4.0) licence.
  7. In case of acceptance, the final published version of the work will be uploaded on the arXiv under the Creative Commons Attribution 4.0 International (CC BY 4.0).
  8. In case of acceptance, the final published version of the work on the arXiv complies with the Crossref DOI guidelines. In particular, all references cited by the submitted work that have a DOI assigned to them contain DOI links.
  9. In case of acceptance and publication in Quantum, the work will not be submitted to other publishing venues, such as journals or conference proceedings.

Rights of the submitter

The submitter is granted the following rights:

  1. At any point prior to acceptance the submitter, as well as any author of the work, can withdraw a work from Quantum. A notification of withdrawal has to be submitted to the handling editor either through the online submission system or by email. Upon receiving a notification of withdrawal prior to acceptance, Quantum terminally rejects the work, thereby ending the peer-review process.
  2. The submitter, as well as any author of the work, can also withdraw a work from Quantum after acceptance and publication by notifying Quantum through email. This however does not trigger a terminal rejection of the work and in particular does not invalidate the rights granted to Quantum during submission. Quantum will instead put a notification on the publication page that the work was withdrawn.

Internal correspondence

Unless explicitly agreed otherwise by all parts involved, all correspondence between editors, referees and authors during the peer review process should be treated as confidential, and may only be shared with the present and future Editorial Board members who have not declared a conflict of interest with the work.

Rights of Quantum

By submitting a work to Quantum, the submitter explicitly grants Quantum the following additional rights:

  1. The right to terminally reject the work, in particular on the basis of the editors’ judgement and/or referee reports.
  2. The right to permanently store and share the work, referee reports, and intermediate correspondence with the referees and all current and future members of the Editorial Board who have not declared a conflict of Interest.
  3. The right to share the identity of the referees with all members of the current and future Editorial Boards who have not declared a conflict of Interest.
  4. The non-exclusive right to share, publish, host, distribute, print, advertise, classify, and otherwise use the manuscript, other parts of the work and all metadata associated with it under the Creative Commons Attribution 4.0 International (CC BY 4.0) licence, unless the work is terminally rejected by Quantum, expect for parts of the work that are covered by incompatible licences. This does not imply any restrictions on the right to publish parts or the entirety of the work of other parties.
  5. The right to deposit the metadata associated with the work in the Crossref system and to assign a DOI to the work.
  6. The right to publish anonymized statistics on submissions and the peer-review process.

Copyright of works published by Quantum

All manuscripts and other parts of works that were previously submitted to Quantum and then published by Quantum, as well as the associated meta-data, including for example a work’s title, abstract, author list, figures, datasets, or popular summary, are published under the Creative Commons Attribution 4.0 International (CC BY 4.0) licence.

For material associated with a manuscript, such as that linked to from the manuscript, or a work’s page on Quantum’s website, especially if hosted on other platforms, other licences can apply.

Each owner of copyright on parts or the entirety of a work submitted to or published by Quantum retains their copyright.
