=== Deprecation of quantum key distributions from governmental institutions ===

Because of the practical problems with quantum key distribution, some governmental organizations recommend the use of post-quantum cryptography (quantum resistant cryptography) instead. For example, the US [[National Security Agency]],<ref name="NSA">{{cite web |title=Quantum Key Distribution (QKD) and Quantum Cryptography (QC) |url=https://www.nsa.gov/Cybersecurity/Quantum-Key-Distribution-QKD-and-Quantum-Cryptography-QC/ |publisher=[[National Security Agency]] |access-date=July 16, 2022}} {{PD-notice}}</ref> [[European Union Agency for Cybersecurity]] of EU (ENISA),<ref>Post-Quantum Cryptography: Current state and quantum mitigation, Section 6 "Conclusion" [https://www.enisa.europa.eu/publications/post-quantum-cryptography-current-state-and-quantum-mitigation]</ref> UK's [[National Cyber Security Centre (United Kingdom)|National Cyber Security Centre]],<ref>[https://www.ncsc.gov.uk/whitepaper/quantum-security-technologies Quantum security technologies]</ref> French Secretariat for Defense and Security (ANSSI),<ref>[https://www.ssicyber.gouv.fr/en/publicationpublications/should-quantum-key-distribution-be-used-for-secure-communications/ Should Quantum Key Distribution be Used for Secure Communications?]</ref> and German Federal Office for Information Security (BSI)<ref>{{cite web | url=https://www.bsi.bund.de/EN/Themen/Unternehmen-und-Organisationen/Informationen-und-Empfehlungen/Quantentechnologien-und-Post-Quanten-Kryptografie/Quantenkryptografie/quantenkryptografie.html | title=Quantum Cryptography }}</ref> recommend post-quantum cryptography.
