<!-- This is a comment. You can erase them or write below --> <!-- Intro: brief description of the protocol --> This [https://www.mdpi.com/1099-4300/23/1/54/htm example protocol] performs the task of [[(Symmetric) Private Information Retrieval|symmetric private information retrieval]] (SPIR) and has unconditional security (a.k.a. information-theoretic security). It is a quantum multi-database one-round protocol, based on a classical multi-database SPIR protocol, that uses [[Quantum Key Distribution|quantum key distribution]] (QKD) to share randomness between servers and to secure classical channels between the user and the servers, and thus do without the assumption of perfectly secured channels of classical multi-database SPIR protocols. <!--Tags: related pages or category --> '''Tags:''' [[:Category:Quantum Enhanced Classical Functionality|Quantum Enhanced Classical Functionality]], [[:Category:Specific Task|Specific Task]], [[Quantum Key Distribution]], [[Information-Theoretic Security]], [[(Symmetric) Private Information Retrieval|Symmetric Private Information Retrieval]], [[Multi-Database]], [[One-Round Protocol]].
