Additive models of probabilistic processes
We propose a new model of probabilistic processes. In this model, a probability is assigned to the action of a prefix and a probability …

Bisimulation indexes and their applications
Bisimulation expresses the equivalence of processes whose external actions are identical. Sometimes we may meet two processes which are …

Lattice-theoretic models of conjectures, hypotheses and consequences
Trillas, Cubillo and Castiñeira [Artificial Intelligence 117 (2000) 255–275] defined several interesting operators in orthocomplemented …

Universal and original-preserving quantum copying is impossible
We show that an arbitrary quantum state cannot be universally 1→2 copied keeping the original copy unchanged. Indeed, the density …

Universal quantum-copying machines: a sufficient and necessary condition
It was shown that the copying quality of the Wootters–Zurek quantum copying machine depends on the input states. So Buzek and Hillery …
