Quantum-metrology estimation of spacetime parameters of the Earth outperforming classical precision
Jan Kohlrus, David Edward Bruschi, Ivette Fuentes
We consider quantum communication schemes where quantum optical signals are exchanged between a source on Earth and a satellite. The background curved spacetime affects the quantum…
Wigner phase of photonic helicity states in the spacetime of the Earth
Jan Kohlrus, Jorma Louko, Ivette Fuentes +1
We study relativistic effects on polarised photons that travel in a curved spacetime. As a concrete application, we consider photons in the gravitational field of the Earth, on a c…
Quantum communications and quantum metrology in the spacetime of a rotating planet
Jan Kohlrus, David Edward Bruschi, Jorma Louko +1
We study how quantum systems that propagate in the spacetime of a rotating planet are affected by the curved background. Spacetime curvature affects wavepackets of photons propagat…
Ultimate precision: Gaussian parameter estimation in flat and curved spacetime
Dominik Šafránek, Jan Kohlrus, David Edward Bruschi +2
Relativistic quantum metrology provides an optimal strategy for the estimation of parameters encoded in quantum fields in flat and curved spacetime. These parameters usually corres…
Thermal noise in BEC-phononic gravitational wave detectors
Carlos Sabín, Jan Kohlrus, David Edward Bruschi +1
Quasiparticles in a Bose-Einstein condensate are sensitive to space-time distortions. Gravitational waves can induce transformations on the state of phonons that can be observed th…
