Bekenstein in "Spectroscopy of the quantum black hole". We propose an entanglement between the black hole information and the information of the Hawking pairs, giving rise to such entanglement entropies. We calculate the entanglement entropy of a black hole using the W state for k > 3 qubits and attempt to obtain the Page curve64 pagesen-USBRAC University thesis reports are protected by copyright.
