英文摘要	Dark energy is investigated from the perspective of quantum cosmology. It is found that, together with an appropriate normal ordering factor q, only when there is dark energy can the cosmological wave function be normalized. This interesting observation may require further attention. The accelerating expansion of our universe has presented a very challenging problem in theoretical physics as well as in cosmology [1,2]. We believe that the character of dark energy is deeply associated with the nature of quantum gravity. In fact, one of the authors showed that dark energy can be well described with the help of the holographic principle, a characteristic feature of any viable theory of quantum gravity. This holographic dark energy model [3] has become one of the most competitive and popular dark energy candidates, which also implies that a deep relation between dark energy and quantum gravity is well appreciated in the community. On the other hand, as an application of quantum physics to the dynamical systems describing closed universes, quantum cosmology is also tightly related to quantum gravity. In spite of some misgivings, interesting hints as regards fundamental mathematical and physical questions can be obtained from quantum cosmology. The studies on quantum cosmology as a generally covariant and highly interacting quantum theory may also provide answers to questions concerning the interplay of symmetries, discrete structures, and so forth. Having noticed the common connection between dark energy, quantum cosmology, and quantum gravity, a natural and interesting question to ask is whether there is a relation between dark energy and quantum cosmology. An answer to this problem may deepen our understanding of the dark energy and shed light on problems related to it.
