Abstract

We investigate a communication scenario in which two inertial observers attempt to securely communicate quantum information via a noisy channel in the presence of a uniformly accelerating eavesdropper. Due to her acceleration, the eavesdropper is subject to Unruh noise which can potentially be exploited to design a secure communication protocol. This problem had previously been studied by Panangaden and co-authors for the special case in which the channel between the inertial observers is noiseless. In this article, we consider noise in the form of a lossy bosonic channel. Our calculations demonstrate that for a fixed acceleration, there is a secure communication protocol provided the noise is below a threshold value.
