A generic construction of quantum-oblivious-key-transfer-based private query with ideal database security and zero failure

Chun-Yan Wei, Xiao-Qiu Cai, Bin Liu +2

Higher security and lower failure probability have always been people's pursuits in quantum-oblivious-key-transfer-based private query (QOKT-PQ) protocols since Jacobi \emph{et al}…
