我们扩展了我们在量子数据隐藏方面的工作[1]-在仅限于执行本地量子操作和经典通信(LOCC)的各方之间隐藏经典数据。我们回顾了使用Bell状态在双方之间隐藏一位的方案，并推导了该隐藏方案的保密性的上下界。我们提供了一个显式的界，表明在我们的方案中可以按位隐藏多个比特。我们给出了一种最多使用一个纠缠EBIT的高效量子计算的隐藏态的准备。提出了一种不使用纠缠的候选数据隐藏方案。我们展示了我们的量子数据隐藏方案如何用于有条件安全的量子比特承诺方案。
We expand on our work on Quantum Data Hiding [1]-hiding classical data among parties who are restricted to performing only local quantum operations and classical communication (LOCC). We review our scheme that hides one bit between two parties using Bell states, and we derive upper and lower bounds on the secrecy of the hiding scheme. We provide an explicit bound showing that multiple bits can be hidden bitwise with our scheme. We give a preparation of the hiding states as an efficient quantum computation that uses at most one ebit of entanglement. A candidate data-hiding scheme that does not use entanglement is presented. We show how our scheme for quantum data hiding can be used in a conditionally secure quantum bit commitment scheme.
