<!-- This is a comment. You can erase them or write below --> <!-- Intro: brief description of the protocol --> This [https://arxiv.org/pdf/0708.2992.pdf example protocol] performs the task of [[(Symmetric) Private Information Retrieval|symmetric private information retrieval]] (SPIR) and has information-theoretic security. It is a single-database two-round quantum SPIR protocol for a classical database, which is based on a [[Quantum Random Access Memory|quantum random access memory]] (qRAM) algorithm. Its security, and more precisely user privacy, is based on a cheat-sensitive strategy: if the malicious server tries to learn the user’s queries, then the user has a non-zero probability of detecting it. As for data privacy, a dishonest user can recover at most two database elements. <!--Tags: related pages or category --> '''Tags:''' [[:Category:Quantum Enhanced Classical Functionality|Quantum Enhanced Classical Functionality]], [[:Category:Specific Task|Specific Task]], [[:Category:Two Party Protocols|Two Party Protocol]], [[Two Round Protocol]], [[Information-Theoretic Security]], [[(Symmetric) Private Information Retrieval|Symmetric Private Information Retrieval]], [[Quantum Private Queries]], [[Quantum Random Access Memory]], [[Single-Database]].
