相对论性(2,3)门限量子秘密共享

Relativistic (2,3)-threshold quantum secret sharing

Mehdi Ahmadi, Ya-Dong Wu, Barry C. Sanders

摘要:

在量子秘密共享协议中,通常假设量子份额的分配和参与者的协作都是惯性进行的。在这里,我们开发了一个量子秘密共享协议,放松这些假设,其中我们考虑的影响,由于加速运动的股份。具体而言,我们解决了(2,3)-阈值连续变量量子秘密共享在非惯性系。为此,我们将相对论运动对腔体内量子场的影响表述为玻色子量子高斯信道。我们研究了量子秘密共享的保真度如何受到量子份额非均匀运动的影响。此外,我们充分描述了正则形式的高斯信道,可用于量子信息处理协议,包括相对论效应。

英文摘要:

In quantum secret sharing protocols, the usual presumption is that the distribution of quantum shares and players' collaboration are both performed inertially. Here we develop a quantum secret sharing protocol that relaxes these assumptions wherein we consider the effects due to the accelerating motion of the shares. Specifically, we solve the (2,3)-threshold continuous-variable quantum secret sharing in non-inertial frames. To this aim, we formulate the effect of relativistic motion on the quantum field inside a cavity as a bosonic quantum Gaussian channel. We investigate how the fidelity of quantum secret sharing is affected by non-uniform motion of the quantum shares. Furthermore, we fully characterize the canonical form of the Gaussian channel which can be utilized in quantum information processing protocols to include relativistic effects.
