Oblivious Transfer from Continuous-Variables QKD with Heterodyne Detection

Year: 2026

Type: conference-paper

Abstract: Practical implementations of oblivious transfer protocols using different quantum key distribution hardware platforms have been proposed in recent years. However, the distinct challenges introduced by setups featuring heterodyne detection of continuous-variables remain an obstacle to the development of protocols with rigorous security analyses. In this work, we introduce a novel oblivious transfer protocol for a continuousvariables quantum key distribution setup using heterodyne detection of coherent states. We provide proofs of correctness and security against malicious adversaries with unbounded computational resources, under the assumption of a well-characterized noisy quantum channel.
