The Journal of Quantum Science and Technology (JQST) ensures the long-term preservation of its scholarly content through the use of PKP Preservation Network (PN), CLOCKSS and LOCKSS archiving systems. These systems are designed to provide robust and reliable preservation services, ensuring that the journal's content remains accessible to the academic community indefinitely.

1. CLOCKSS: CLOCKSS (Controlled LOCKSS) operates on a global scale to safeguard scholarly content against loss due to extraordinary events. Its network of archive nodes, distributed across different geographic and political regions, is designed to store and preserve content in a secure and reliable manner. CLOCKSS guarantees that, in case of a 'trigger event' like the loss of content from the publisher, the stored works remain accessible and usable for future generations.

2. LOCKSS: The LOCKSS (Lots of Copies Keep Stuff Safe) system employs a decentralized and distributed approach to preservation. Participating libraries across the world create and store local copies of digital content. This method ensures protection against technological and organizational failures, preserving the integrity and accessibility of the journal's content over time.

3. PKP Preservation Network (PN): As part of the Public Knowledge Project, the PKP PN provides an additional preservation framework, specifically for journals using the Open Journal Systems (OJS). This network aids in safeguarding digital academic content through its distinct yet complementary preservation techniques. PKP PN ensures that the journal's content, managed through OJS, is preserved and remains accessible for long-term academic and research use.

Through the combination of CLOCKSS, LOCKSS, and PKP PN, the journal establishes a robust and multi-faceted archiving strategy, ensuring the preservation of its scholarly articles and safeguarding their accessibility for future research and academic endeavors.
