A black hole is an object whose gravity is so strong that nothing, not even light, can escape its grasp. However, applying quantum field theory on a black hole background, Stephen Hawking showed that black holes are not completely black. In fact, they seem to emit a form of radiation that was named the Hawking radiation. The Hawking radiation appears to be thermal and in a quantum state that is independent of the initial state that formed the black hole; instead, it solely depends on the black hole's total mass, spin, and electric charge. A problem arises when we consider an initial system that collapses, forms a black hole, and eventually the black hole evaporates completely through Hawking radiation. Since Hawking radiation depends solely on the black hole's total mass, spin, and electric charge, it implies that numerous distinct initial states could all lead to the same final state. Consequently, the intricate details of the initial state seem to be lost, which contradicts the unitarity of evolution of closed systems, a fundamental principle of quantum mechanics. The unitarity principle implies that closed systems evolv
