Robustness of entanglement in Hawking radiation for optical systems immersed in thermal baths
Ivan Agullo, Anthony J. Brady, Dimitrios Kranas
Entanglement is the quantum signature of Hawking's particle pair-creation from causal horizons, for gravitational and analog systems alike. Ambient thermal fluctuations, ubiquitous…
Symplectic circuits, entanglement, and stimulated Hawking radiation in analog gravity
Anthony J. Brady, Ivan Agullo, Dimitrios Kranas
We introduce a convenient set of analytical tools (the Gaussian formalism) and diagrams (symplectic circuits) to analyze multi-mode scattering events in analog gravity, such as pai…
Event horizons are tunable factories of quantum entanglement
Ivan Agullo, Anthony J. Brady, Dimitrios Kranas
That event horizons generate quantum correlations via the Hawking effect is well known. We argue, however, that the creation of entanglement can be modulated as desired, by appropr…
