Quantum information and quantum metrology can be used to study
gravitational effects such as gravitational waves and the universality of
the equivalence principle. On one hand, the possibility of carrying out
experiments to probe gravity using quantum systems opens an avenue to
deepen our understanding of the overlap of these theories. On the other
hand,  incorporating relativity in quantum technologies promises the
development of a new generation of relativistic quantum applications of
relevance in Earth-based and space-based setups. In this talk, I will

Quantum information and quantum metrology can be used to study
gravitational effects such as gravitational waves and the universality of
the equivalence principle. On one hand, the possibility of carrying out
experiments to probe gravity using quantum systems opens an avenue to
deepen our understanding of the overlap of these theories. On the other
hand,  incorporating relativity in quantum technologies promises the
development of a new generation of relativistic quantum applications of
relevance in Earth-based and space-based setups. In this talk, I will
introduce a framework for the application of quantum information and
quantum metrology techniques to relativistic quantum fields.  I will show
how, using this framework, we have been able to develop an accelerometer
and a gravitational wave detector that exploit both quantum and
relativistic effects. I will discuss some of my future research plans in
relativistic quantum metrology including ideas to estimate with high
precision spacetime parameters such as the Earth's Schwarzchild radius,
develop a new generation of gravimeters and study the effects of motion
and gravity on quantum clocks.
