THE INFORMATION PROBLEM. “For a sub-system of a larger quantum system, its thermodynamic entropy is usually identified with its number of quantum degrees of freedom, i.e., the logarithm of the number of its quantum states, and corresponds to its maximum possible von Neumann entropy as part of a larger system. The assumption, called the “central dogma” that this is true for black holes is what leads to the black hole information problem.”
