Abstract
We review aspects of black hole thermodynamics, and show how entanglement
of a quantum field between the inside and outside of a horizon can account for the areaproportionality
of black hole entropy, provided the field is in its ground state. We show that
the result continues to hold for Coherent States and Squeezed States, while for Excited States,
the entropy scales as a power of area less than unity. We also identify location of the degrees
of freedom which give rise to the above entropy.
