“…Moreover, the effect of gravity is believed to be locally equivalent to the effect of non-inertial motion of the observer. And as such can still lead to non-trivial consequences in the dynamics of quantum fields including decay rates of unstable particles [3]. Therefore a simpler approach to the effect of gravity on quantum fields has been developed.…”

We use the formalism of noisy Gaussian channels to derive explicit transformation laws describing how an arbitrary multimode Gaussian state of a scalar quantum field is perceived by a number of accelerating observers, each having access to at least one of the modes. Our work, which generalizes earlier results of Ahmadi, et al., Phys. Rev. D 93, 124031 (2016), is the next step torwards a better understanding of the effect of gravity on the states of quantum fields. arXiv:1804.08307v2 [quant-ph] 26 Apr 2018Upon the substitution, we have:

“…The effect of gravity can be taken into account as a curved dynamical background which modifies the equations of quantum field theory. This, has non-trivial effects even on fundamental phenomena such as the decay rate of unstable particles [13]. Furthermore, gravity is locally equivalent to non-inertial motion according to * Electronic address: robpierin@gmail.com the equivalence principle.…”

The domain of quantum technologies has been recently broaden to satellites orbiting the earth. Long distances communication protocols cannot ignore the presence of the gravitational field and its effects on the quantum states. Here, we provide a general method to investigate how gravity affects the performance of various quantum key distribution protocols for continuous variable states of localized wave packets. We show that the consequences of gravity strongly depend on the configuration and the cryptographic scheme used.
