Quantum entanglement is a phenomenon in which two or more particles become correlated in such a way that the state of one particle is intrinsically connected to the state of the others, regardless of the distance between them. While quantum entanglement is a fascinating concept, it is important to note that it does not provide a means for transmitting information faster than the speed of light.
Regarding black holes, the concept you mentioned about transmitting basic quantum information from a black hole is likely referring to the theoretical idea known as "black hole information paradox." This paradox arises due to the conflict between general relativity and quantum mechanics.
According to classical general relativity, when matter falls into a black hole, all information about that matter appears to be lost forever beyond the event horizon. However, quantum mechanics suggests that information is never truly lost and that it should always be conserved.
Quantum entanglement has been explored in the context of black holes as a potential mechanism for information preservation. The idea is that if an entangled particle falls into a black hole, the entanglement links the particle inside the black hole with its partner outside. This theoretical notion has led to studies on the possibility of extracting information from a black hole through the measurement of the entangled partner outside.
However, it's important to note that the study of black holes and their properties, including information loss and quantum entanglement, is an active area of research, and many questions remain unanswered. The nature of black holes and their behavior within the framework of quantum mechanics is still a topic of ongoing scientific investigation.
To summarize, while quantum entanglement is an intriguing concept, its relation to black holes and the preservation of information within them is still a subject of exploration and theoretical investigation. The full understanding of information preservation in the context of black holes requires the development of a theory that successfully combines general relativity and quantum mechanics, such as a theory of quantum gravity, which is an area of active research in theoretical physics.
