Relativistic quantum information and black hole physics

Relativistic quantum information investigates how special and general relativity affect quantum information processing and how quantum technology can be used to test the fundamental physics.

Black holes are not only one of the most exciting objects in the Universe and an inexhaustible source of inspiration for sci-fi writers, but they are also the interface where the two most fundamental theories of physics --- quantum mechanics and general relativity – need to be combined.

What we do

We study effects of gravity on light propagation, what we can learn from its study and how relativity affects quantum communications on near-Earth orbits.

We study black holes and what it takes to the observed astrophysical black holes to have  the `actual’ black hole properties such as horizons, does this make a difference and if yes, how it can be detected.

Classification of the potential explanation of the compact objects. ɛ measures how close they are to black holes (mathematical or physical)

If the equipment to optically test the Einstein equivalence principle is put on the orbit of one of the satellites that communicate with Matera ground station in Italy, then the red line is the gravitational effect if the Einstein equivalence principle works exactly as we believe.
