Counterfactuals in quantum theory are briefly reviewed and it is argued that they are very different from counterfactuals considered in the general philosophical literature. The issue of time symmetry of quantum counterfactuals is considered and a novel timesymmetric definition of quantum counterfactuals is proposed. This definition is applied for analyzing several controversies related to quantum counterfactuals. 1 There are very many philosophical discussions on the concept of counterfactuals and especially on the time’s arrow in counterfactuals. There is also a considerable literature on counterfactual in quantum theory. In order to be a helpful tool in quantum theory counterfactuals have to be rigorously defined. Unfortunately, the concept of counterfactuals is vague 1 and this leads to several controversies. I, however, believe that since quantum counterfactuals appear in a much narrow context than in general discussions on counterfactuals, they can be defined unambiguously. I will briefly review counterfactuals in quantum theory and will propose a rigorous definition which can clarify several issues, in particular, those related to the timesymmetry of quantum counterfactuals.

A definition is proposed to give precise meaning to the counterfactual statements that often appear in discussions of the implications of quantum mechanics. Of particular interest are counterfactual statements which involve events occurring at spacelike separated points, which do not have an absolute time ordering. Some consequences of this definition are discussed. 1
