Query: Quantum estimation of the Schwarzschild space-time parameters of the
  Earth   We propose a quantum experiment to measure with high precision the
Schwarzschild space-time parameters of the Earth. The scheme can also be
applied to measure distances by taking into account the curvature of the
Earth's space-time. As a wave-packet of (entangled) light is sent from the
Earth to a satellite it is red-shifted and deformed due to the curvature of
space-time. Measurements after the propagation enable the estimation of the
space-time parameters. We compare our results with the state of the art, which
involves classical measurement methods, and discuss what developments are
required in space-based quantum experiments to improve on the current
measurement of the Schwarzschild radius of the Earth.
