摘要

摘要提出了一种利用非厄米运算增强振幅阻尼噪声下量子密集编码容量的新方法。在非厄米运算的帮助下,我们证明了量子密集编码的容量总是大于1的任何两个量子位态。特别是在退相干强度强的情况下,非厄米运算比退相干强度小的情况下能更有效地提高量子密集编码。我们的研究结果为量子环境中量子密集编码的保护提供了新的思路。

Improving the capacity of quantum dense coding via non-Hermitian operation
Abstract We propose a novel method to enhance the capacity of quantum dense coding under amplitude damping noise using non-Hermitian operations. With the assistance of non-Hermitian operations, we show that the capacity of quantum dense coding can always be larger than 1 for any two-qubit states. In particular, the non-Hermitian operation can improve quantum dense coding more efficiently in the case of strong decoherence strength than those with small decoherence strength. Our results shed new light on the protection of quantum dense coding in a quantum environment.
