摘要:

奇偶不可知随机存取码(PORAC)是一类涉及发送方 Alice 和接收方 Bob 的通信博弈。在此类博弈中,Alice 向 Bob 传递的通信量受到奇偶不可知(PO)条件约束,从而使其输入的奇偶信息对 Bob 保持不可知。操作理论中的 PO 条件可在满足制备非语境性的本体论模型中等价表示。本文对现有两能级 PORAC 给出了一种非平凡推广,并推导了该博弈在制备非语境本体论模型中的获胜概率。我们证明,在我们的广义 PORAC 中,量子理论通过预测更高的获胜概率,表现优于制备非语境模型。

英文摘要:

The parity-oblivious random-access-code (PORAC) is a class of communication games involving a sender (Alice) and a receiver (Bob). In such games, Alice's amount of communication to Bob is constraint by the parity-oblivious (PO) conditions, so that the parity information of her inputs remains oblivious to Bob. The PO condition in an operational theory is equivalently represented in an ontological model that satisfies the preparation noncontextuality. In this paper, we provide a nontrivial generalization of the existing two-level PORAC and derive the winning probability of the game in the preparation noncontextual ontological model. We demonstrate that the quantum theory outperforms the preparation noncontextual model by predicting higher winning probability in our generalized PORAC.
