Event horizons are tunable factories of quantum entanglement

Louisiana State University physicists have leveraged quantum information theory techniques to reveal a mechanism for amplifying, or "stimulating," the production of entanglement in the Hawking effect in a controlled manner. Furthermore, these scientists propose a protocol for testing this idea in the laboratory using artificially produced event horizons. These results have been recently published in Physical Review Letters, "Quantum aspects of stimulated Hawking radiation in an analog white-black hole pair," where Ivan Agullo, Anthony J. Brady and Dimitrios Kranas present these ideas and apply them to optical systems containing the analog of a pair white-black hole.

Stephen Hawking added more mystique to the character of black holes by showing that, once quantum effects are considered, a black hole isn't really black at all but, instead, emits radiation, as if it was a hot body, gradually losing mass in the so-called "Hawking evaporation process." Further, Hawking's calculations showed that the emitted radiation is quantum mechanically entangled with the bowels of the black hole itself. This entanglement is the quantum signature of the Hawking effect. This astounding result is difficult, if not impossible, to be tested on astrophysical black holes, since the faint Hawking radiation gets overshined by other sources of radiation in the cosmos.

On the other hand, in the 1980's, a seminal article by William Unruh established that the spontaneous production of entangled Hawking particles occurs in any system that can support an effective event horizon. Such systems generally fall under the umbrella of "analog gravity systems" and opened a window for testing Hawking's ideas in the laboratory.

In between my divorce and regaining my sanity I had a quantum entanglement with a tunable woman.

Good cast, terrible movie...

Every time they monkey around with this stuff another sock goes missing from my dryer.
