With the appearance of quantum theory, more and more people began to focus on this area, but it is so confusing that its education is very difficult. First, the article discussed a virtual laboratory system for quantum mechanics education. Second, the rule setting is also analyzed to provide us an effective proof system and correctness system to affirm virtual quantum laboratory. Third, And virtual laboratory is studied from its operational system, rule setting and semantics environment which includes the input and output of virtual laboratory. Last, some conclusions and future directions are given at the end of the paper.
