我们确定的量子通道对应的高斯量子态与一个已经形成的史瓦西黑洞的相互作用。利用单模玻色子高斯信道分类的最新进展,我们发现(有一个例外)黑洞高斯信道位于有损信道C(损耗),放大信道C(amp)和经典噪声信道B2的非纠缠破坏子集中。我们发现通道参数依赖于黑洞的质量和周围的势垒的属性it.This分类使我们能够计算的经典和量子容量的黑洞和估计的量子容量没有听话的量子容量表达式存在今天。我们讨论这些发现的光的黑洞量子信息损失问题。
We identify the quantum channels corresponding to the interaction of a Gaussian quantum state with an already formed Schwarzschild black hole. Using recent advances in the classification of one-mode bosonic Gaussian channels we find that (with one exception) the black hole Gaussian channels lie in the non-entanglement breaking subset of the lossy channels C(loss), amplifying channels C(amp) and classical-noise channels B2. We show that the channel parameters depend on the black hole mass and the properties of the potential barrier surrounding it. This classification enables us to calculate the classical and quantum capacity of the black hole and to estimate the quantum capacity where no tractable quantum capacity expression exists today. We discuss these findings in the light of the black hole quantum information loss problem.
