Gravitationally Induced Entanglement Between Particles in Harmonic Traps: Limits for Gaussian States
Julia Tokarska, Andrzej Dragan
Gravitationally induced entanglement has been proposed as a probe of the quantum nature of gravity. This work analyzes a system of two particles in harmonic traps interacting only…

The relativistic reason for quantum probability amplitudes
Karol Sajnok, Kacper Dębski, Andrzej Dragan
We show that the quantum-mechanical probability distribution involving complex probability amplitudes can be derived from three natural conditions imposed on a relativistically inv…

Detection of quantum entanglement across the event horizon
Patryk Michalski, Andrzej Dragan
We investigate the problem of distinguishing between separable and entangled states of two quantum wave packets, one of which falls into a black hole. Intuitively, one might expect…
