The black hole 1es 1927+654
A new discovery revealed that a spy hidden inside a black hole could obtain information about quantum objects abroad.
One presented two weeks ago at the Global Summit of Physics of the American Society of Physics in the USA, suggested that the Quantum espionage can work – even from the inside of a black hole.
Daine Danielsonfrom the University of Chicago, studied how the structure of spacetime influences quantum objects.
To explain their results, the researcher served a thought experience in which two people end up separated by one of the most extreme objects of spacetime.
Alice (Person 1) has a quantum object and places it in a “overlap” that combines two of its normal states in a way that can only exist in the quantum domain. Bob (Person 2), in turn, wants to secretly obtain information about this object of Alice.
“Bob doesn’t want to be caught, but It’s smart and realizes that you can hide inside a black hole“Explained Danielson, quoted by New Scientist.
Physicists know that information cannot escape a black hole, but Danielson tried to see if Bob could still achieve his goal.
As explained by New Scientist, quantum overlays are fragile. For this reason, external influences (such as simple environmental disturbances), can cause the overlap to a unique and un -mixed state.
This process is designated by decoration.
Using, the researchers mathematically proved that The information that Bob can obtain from the interior of the black hole corresponds exactly to the extent of the decoration that Alice would observe on its object abroad.
For example, if Bob hid in a ball made of normal matter instead of a black hole, the flow of information between him and Alice would be different.
For Daine Danielson, this discovery is a big step towards connecting the space-time structure to quantum information flow; and may mean that the spacetime structure is not fundamental, but a consequence of the laws governing the way quantum information can be exchanged.
“There is a hope that this can give us an idea how space and time can emerge from the principles of information theory,” the physicist said.
In New Scientist, Alex LupsascaFrom the University of Vanderbilt, he said that although it is already known that black holes were champions of extreme cosmic behavior, the new work points to “another way of being the best in everything they do.”
“Black holes can destroy overlays Quantum with its strong severity, and do it as quickly as possible, ”he praises.
