论文摘要
我们考虑在右侧林格楔块中均匀加速的发件人之间的连续变量量子传送方案，仅限于未来光锥的保形接收器和Minkowski真空吸尘器中的惯性观察者。使用非扰动量子电路模型，加速的观察者与田地的Rindler模式单位相互作用，从而将真空作为资源访问。我们发现，尽管惯性观察者的rindler倒置的Minkowski真空状态被加速观察者送达并传送，尽管惯性观察者的态度混合了，尽管经典方差降低了经典限制。这是一个令人惊讶的结果，因为直接从加速观察者传播的相同状态似乎是纯连贯的状态到惯性观察者。随着加速度的增加，状态的变质是由反对效应的相互作用引起的：输出状态中真空噪声的降低，从而获得了更强的纠缠资源，这受到由于存在UNRUH辐射而导致的热噪声的扩增。
We consider a continuous-variable quantum teleportation protocol between a uniformly accelerated sender in the right Rindler wedge, a conformal receiver restricted to the future light cone, and an inertial observer in the Minkowski vacuum. Using a non-perturbative quantum circuit model, the accelerated observer interacts unitarily with the Rindler modes of the field, thereby accessing entanglement of the vacuum as a resource. We find that a Rindler-displaced Minkowski vacuum state prepared and teleported by the accelerated observer appears mixed according to the inertial observer, despite a reduction of the quadrature variances below classical limits. This is a surprising result, since the same state transmitted directly from the accelerated observer appears as a pure coherent state to the inertial observer. The decoherence of the state is caused by an interplay of opposing effects as the acceleration increases: the reduction of vacuum noise in the output state for a stronger entanglement resource, constrained by the amplification of thermal noise due to the presence of Unruh radiation.
