  In a recent paper [1], we proposed that the quantum states of black hole
responsible for the Bekenstein-Hawking entropy are given by Bell states of
Fermi quanta in the interior of black hole. In this paper, we include the
effect of tunneling on these entangled states and show that partial tunneling
of these Bell states of Fermi quanta give rises to the Page curve of Hawking
radiation. We also show that the entirety of information initially stored in
the black hole is returned to the outside via the Hawking radiation.
