Quantum black hole: What is that?

In this paper we are trying to explain our point of view on what a quantum blade hole is. The ideas are based on the previous works by the author and his collaborators where the concrete models of quantum black holes were con structed. It is argued that the main feature of quantum black holes that wo uld allow us to distinguish them from other quantum object is some specific quantum radiation. Such a radiation in the quasiclassical limit is just th e Hawking evaporation if the change in the black hole mass due to radiation can be neglected.
