  Treating macro-black hole as quantum states, and using Brown-York quaselocal
gravitational energy definition and Heisenberg uncertainty principle, we find
out the classical horizon with singularity spreads into a quantum horizon in
which the space-time is non-commutative and the spread range is determined
dynamically. A Quantum Field Theory (QFT) model in curved space with quantum
horizon is constructed. By using it, the black hole entropy and the Hawking
temperature are calculated successfully. The $\phi-$field mode number is
predicted and our quantum horizon model favors to support the Minimal
Super-symmetric Standard Model.
