Contextuality from the vacuum
Caroline Lima, MarÃa Rosa Preciado-Rivas, Sanchit Srivastava
Contextuality, a key resource for quantum advantage, describes systems in which the outcome of a measurement is not independent of other compatible measurements, in contrast to cla…
Harvesting Information Across the Horizon
S. Wang, M. R. Preciado Rivas, R. B. Mann
The effect of black holes on entanglement harvesting has been of considerable interest over the past decade. Research involving stationary Unruh-DeWitt (UDW) detectors near a (2+1)…
Deep in the knotted black hole
Massimiliano Spadafora, Manar Naeem, MarÃa R. Preciado-Rivas +2
We consider the transition rate of a freely falling Unruh-DeWitt detector, coupled linearly to a massless scalar quantum field prepared in the Hartle-Hawking-Israel state, as a pro…
Singular excitement beyond the horizon of a rotating black hole
Sijia Wang, MarÃa Rosa Preciado-Rivas, Massimiliano Spadafora +1
Previous studies have shown that an Unruh-DeWitt (UDW) detector, when coupled linearly to a massless scalar field and permitted to fall radially into certain black holes, will exhi…
Accelerated detector in a superposed spacetime
Lakshay Goel, Everett A. Patterson, MarÃa Rosa Preciado-Rivas +3
In pursuit of a full-fledged theory of quantum gravity, operational approaches offer insights into quantum-gravitational effects produced by quantum superposition of different spac…
More Excitement Across the Horizon
MarÃa R. Preciado-Rivas, Manar Naeem, Robert B. Mann +1
An Unruh-DeWitt (UDW) detector falling radially into a four-dimensional Schwarzschild black hole, coupled linearly to a massless scalar field that has been prepared in the Hartle-H…
