摘要: The search for a semantics higher-order quantum computation leads naturally to the study of categories normed cones. In first part this paper, we develop theory continuous cones, and prove some their basic properties, including Hahn-Banach style theorem. We then describe two different concrete -autonomous these is built from completely positive maps as in author’s first-order computation. second category reformulation Girard’s coherent spaces. also point out why ultimately, neither satisfactory model
