论文摘要
讨论了使用最少数量的Qubits掩盖加速的两分Quibit系统的可能性。结果表明，该信息可以在纠缠的局部状态或非本地可分离状态中掩盖。我们检查这些状态的每个分区都满足掩盖条件。由于存在非本地分离分区，因此可以认为它是一种量子数据隐藏方案。在蒙版纠缠状态中编码的局部 /非本地信息与加速过程的脱碳是可靠的。随着初始纠缠值的增加，通过纠缠/可分离掩蔽状态估算加速度参数的可能性会增加。通过量化加速状态及其子系统的保真度来检查掩蔽过程的效率。结果表明，蒙版状态的保真度在小初始加速下最大，而最低保真度则超过$ 96 \％$。
The possibility of masking an accelerated two-qubit system by using a minimum number of qubits is discussed. It is shown that, the information may be masked in either entangled local states or product non-local separable states. We examine that each partition of these states satisfies the masking conditions. Due to the presence of non-local separable partition, one may consider that it is a type of quantum data hiding scheme. The local /non-local information encoded in the masked entangled state is robust against the decoherence of the acceleration process. The possibility of estimating the acceleration parameter via the entangled/separable masked state increases as the initial entanglement value increases. The efficiency of the masking process is examined by quantifying the fidelity of the accelerated state and its subsystems. It is shown that, the fidelity of the masked state is maximum at small initial acceleration, while the minimum fidelity is more than $96\%$.
