Quantum Superposition of Black Holes Enhances Communication Protocols
The interplay between black holes and quantum information has revealed deep connections between gravity and quantum mechanics. For example, the classical spacetime geometry of a black hole has been shown to degrade quantum entanglement shared by nearby observers, one of whom is in free fall. Here, we examine how this picture changes when the black hole’s mass degrees of freedom are allowed to exist in a coherent quantum superposition, corresponding to a superposition of disti
The interplay between black holes and quantum information reveals that placing a black hole's mass in a quantum superposition can mitigate the loss of entanglement between nearby observers. This quantum coherence, corresponding to a superposition of distinct spacetime geometries, enhances the performance of quantum communication protocols operating near the black hole. Unlike classical black holes, which degrade entanglement, these quantum superpositions act as a resource to improve communication fidelity. This finding deepens our understanding of the connections between gravity and quantum mechanics, suggesting potential applications in quantum information science.
The finding that quantum superposition of black hole states can enhance quantum communication protocols offers new insights into the relationship between gravity and quantum mechanics, with potential applications in information science.
