Fault-tolerant symmetrically-private information retrieval
Tian‐Yin Wang, Xiao‐Qiu Cai, Ruiling Zhang · International Journal of Modern Physics B · 2016
We propose two symmetrically-private information retrieval protocols based on quantum key distribution, which provide a good degree of database and user privacy while being flexible, loss-resistant and easily generalized to a large database similar to the precedent works. Furthermore, one protocol is robust to a collective-dephasing noise, and the other is robust to a collective-rotation noise.
