Abstract

In this paper, we propose a novel Probabilistic Quantum Oblivious Transfer (also known as Quantum Private Query or QPQ) scheme with full Device-Independent (DI) certification. To the best of our knowledge, this is the first time we provide such a full DI-QPQ scheme using EPR pairs. Our proposed scheme exploits the self-testing of shared EPR pairs along with the self-testing of projective measurement operators in a setting where the client and the server do not trust each other. To certify full device independence, we exploit a strategy to self-test a particular class of POVM elements that are used in the protocol. Further, we provide formal security analysis and obtain an upper bound on the maximum cheating probabilities for both the dishonest client as well as the dishonest server.
