Lasers to Solve the Black Hole Information Paradox?
However, information cannot be copied perfectly in the quantum world (a concept known as the no-cloning theorem), “but it turns out that the spontaneous emission of radiation (the Hawking radiation of the black hole) conveniently prevents perfect cloning ...
Plugging the hole in Hawking's black hole theory
Ironically, it has been hiding in plain sight for years. Hawking's famous black hole radiation is an example of so-called spontaneous emission of radiation, but it is only part of the story. There must also be the possibility of stimulated emission ...
How To Build A Black Hole Laser
Indeed, Chinese physicists built just such an artificial black hole back in 2009 ... of radiation at a hole’s point of no return, called its event horizon. This spontaneous emission of radiation is a curious and complex phenomenon.
Viewpoint: Lasers of Pure Sound
prefer to call them, inspired by Star Trek’s fictional weapon: “phasers” (short for phonon amplification by stimulated emission of radiation). A number of questions remain to be addressed: How can the coherent acoustic beam be coupled to the outside ...
How Lasers Really Work
This process is called spontaneous emission." Believing that if just the ... short forMicrowave Amplification by Stimulated Emission of Radiation, which amplified microwaves. The Townes-Schawlow proposal stirred Theodore Maiman of the Hughes Research ...
