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…
Generating entanglement between two-dimensional cavities in uniform acceleration
Bartosz Regula, Antony R. Lee, Andrzej Dragan +1
Moving cavities promise to be a suitable system for relativistic quantum information processing. It has been shown that an inertial and a uniformly accelerated one-dimensional cavi…
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…
Relativistic Motion with Superconducting Qubits
S. Felicetti, C. Sabín, I. Fuentes +3
We show how the dynamical modulation of the qubit-field coupling strength in a circuit quantum electrodynamics architecture mimics the motion of the qubit at relativistic speeds. T…
Quantum parameter estimation using multi-mode Gaussian states
Dominik Šafránek, Antony R. Lee, Ivette Fuentes
Gaussian states are of increasing interest in the estimation of physical parameters because they are easy to prepare and manipulate in experiments. In this article, we derive formu…
