    Sammanfattning : The black hole information paradox, which states that the evaporation of black holes due to Hawking radiation results in a violation of the conservation of quantum information, is arguably one of the most fundamental problems in all of modern physics. Through the equivalence principle, the essence of the problem can be understood and studied in the context of much simpler flat spacetime (described by the theory of special relativity); in this context the Hawking radiation takes the form of the so-called Unruh effect, a thermal effect in the vacuum of a Minkowski quantum field theory that can be measured by accelerated observers.

    Nyckelord :Black holes; quantum entanglement; entanglement; Hawking radiation; the black hole information paradox; information paradox; Svarta hål; kvantintrassling; kvantsammanflätning; kvantkorrelation; informationsparadoxen; svarta hål informationsparadoxen; Hawkingstrålning;

    Sammanfattning : The black hole information paradox arises when quantum mechanical effects are considered in the vicinity of the event horizon of a black hole. In this report we describe the fundamental properties of quantum mechanical systems and black holes that lead to the information paradox, with focus on quantum entanglement. LÄS MER
